SAFETY PRECAUTIONS

The machine is equipped with safety devices which serve to protect personnel and the machine itself from hazards arising from unforeseen accidents. However, operators must not rely exclusively on these safety devices: they must also become fully familiar with the safety guidelines presented below to ensure accidentfree operation. This instruction manual and the warning signs attached to the machine cover only those hazards which Okuma can predict. Be aware that they do not cover all possible hazards.

1. Precautions Relating to Installation

(1) Please be noted about a primary power supply as follows.

• Do not draw the primary power supply from a distribution panel that also supplies a major

noise source (for example, an electric welder or electric discharge machine) since this could cause malfunction of the CNC unit.

• If possible, connect the machine to a ground not used by any other equipment. If there is

no choice but to use a common ground, the other equipment must not generate a large amount of noise (such as an electric welder or electric discharge machine).

(2) Installation Environment

Observe the following points when installing the control enclosure.

• Make sure that the CNC unit will not be subject to direct sunlight.

• Make sure that the control enclosure will not be splashed with chips, water, or oil.

• Make sure that the control enclosure and operation panel are not subject to excessive

vibrations or shock.

• The permissible ambient temperature range for the control enclosure is 5 to 40°C.

• The permissible ambient humidity range for the control enclosure is relative humidity 50%

or less at 40°C (no condensation).

• The maximum altitude at which the control enclosure can be used is 1000 m (3281ft.).

2. Points to Check before Turning on the Power

(1) Close all the doors of the control enclosure and operation panel to prevent the entry of water,

chips, and dust.

(2) Make absolutely sure that there is nobody near the moving parts of the machine, and that there

are no obstacles around the machine, before starting machine operation.

(3) When turning on the power, turn on the main power disconnect switch first, then the CONTROL

ON switch on the operation panel.

5262-E P-(ii)

SAFETY PRECAUTIONS

3. Precautions Relating to Manual/Continuous Operation

(1) Follow the instruction manual during operation.

(2) Do not operate the machine with the front cover, chuck cover, or another protective cover

removed.

(3) Close the front cover before starting the machine.

(4) When machining the initial workpiece, check for machine operations, run the machine under no

load to check for interference among components, cut the workpiece in the single block mode, and then start continuous operation.

(5) Ensure your safety before rotating the spindle or moving a machine part.

(6) Do not touch chips or workpiece while the spindle is rotating.

(7) Do not stop a rotating part with hand or another means.

(8) Check that the condition of hydraulic chuck jaws as mounted, operating pressure, and maxi-

mum permissible revolving speed.

(9) Check the condition and location of the cutting tool as mounted.

(10) Check the tool offset value.

(11) Check the zero offset value.

(12) Check that the SPINDLE OVERRIDE and FEEDRATE OVERRIDE dials on the NC operation

panel are set to 100%.

(13) When moving the turret, check the software limits for X- and Z-axes or the locations of limit

switch dogs to prevent interference with the chuck and tailstock.

(14) Check the location of the turret.

(15) Check the location of the tailstock.

(16) Cut workpieces with a transmitted power and torque within the permissible range.

(17) Chuck each workpiece firmly.

(18) Check that the coolant nozzle is properly located.

4. Precautions Relating to the ATC

(1) The tool clamps of the magazine, spindle, etc., are designed for reliability, but it is possible that

a tool could be released and fall in the event of an unforeseen accident, exposing you to danger: do not touch or approach the ATC mechanism during ATC operation.

(2) Always inspect and change tools in the magazine in the manual magazine interrupt mode.

(3) Remove chips adhering to the magazine at appropriate intervals since they can cause

misoperation. Do not use compressed air to remove these chips since it will only push the chips further in.

(4) If the ATC stops during operation for some reason and it has to be inspected without turning the

power off, do not touch the ATC since it may start moving suddenly.

5262-E P-(iii)

SAFETY PRECAUTIONS

5. On Finishing Work

(1) On finishing work, clean the vicinity of the machine.

(2) Return the ATC, APC and other equipment to the predetermined retraction position.

(3) Always turn off the power to the machine before leaving it.

(4) To turn off the power, turn off the CONTROL ON switch on the operation panel first, then the

main power disconnect switch.

6. Precautions during Maintenance Inspection and When Trouble Occurs

In order to prevent unforeseen accidents, damage to the machine, etc., it is essential to observe the following points when performing maintenance inspections or during checking when trouble has occurred.

(1) When trouble occurs, press the emergency stop button on the operation panel to stop the

machine.

(2) Consult the person responsible for maintenance to determine what corrective measures need

to be taken.

(3) If two or more persons must work together, establish signals so that they can communicate to

confirm safety before proceeding to each new step.

(4) Use only the specified replacement parts and fuses.

(5) Always turn the power off before starting inspection or changing parts.

(6) When parts are removed during inspection or repair work, always replace them as they were

and secure them properly with their screws, etc.

(7) When carrying out inspections in which measuring instruments are used - for example voltage

checks - make sure the instrument is properly calibrated.

(8) Do not keep combustible materials or metals inside the control enclosure or terminal box.

(9) Check that cables and wires are free of damage: damaged cables and wires will cause current

leakage and electric shocks.

(10) Maintenance inside the Control Enclosure

a. Switch the main power disconnect switch OFF before opening the control enclosure door.

b. Even when the main power disconnect switch is OFF, there may some residual charge in

the MCS drive unit (servo/spindle), and for this reason only service personnel are permitted to perform any work on this unit. Even then, they must observe the following precautions.

• MCS drive unit (servo/spindle)

The residual voltage discharges two minutes after the main switch is turned OFF.

c. The control enclosure contains the NC unit, and the NC unit has a printed circuit board

whose memory stores the machining programs, parameters, etc. In order to ensure that the contents of this memory will be retained even when the power is switched off, the memory is supplied with power by a battery. Depending on how the printed circuit boards are handled, the contents of the memory may be destroyed and for this reason only service personnel should handle these boards.

(11) Periodic Inspection of the Control Enclosure

a. Cleaning the cooling unit

The cooling unit in the door of the control enclosure serves to prevent excessive temperature rise inside the control enclosure and increase the reliability of the NC unit. Inspect the following points every three months.

• Is the fan motor inside the cooling unit working?

The motor is normal if there is a strong draft from the unit.

• Is the external air inlet blocked?

If it is blocked, clean it with compressed air.

7. General Precautions

SECTION 1 TURRET OPERATION

1. Overview

This section describes the functions and operations of the turrets installed in MACTURN and MULTUS series. MACTURN and MULTUS series can move its saddle in three directions X-axis, Y-axis, and Z-axis. The turret rotates around the Y-axis. The turret indexing function is available in two modes: “B-axis 1° indexing” by 1°, and “B-axis 1/ 1000° indexing” by 0.001°. However, only “B-axis 1/1000° indexing” is available in MULTUS series.

SECTION 1 TURRET OPERATION

2. Turret Indexing Control

Since the turret of MACTURN and MULTUS series rotates around the Y-axis, a single tool can be used on the front or on a side according to the direction the turret is indexed.

2-1. Turret Index Position

(1) Base cutting position

One of the basic indexing operations of the turret for MACTURN and MULTUS series machines is “base cutting position” indexing. The base cutting position means the state the tool attached faces the Z-axis direction. When a second spindle is equipped, the turret indexing position is 180 degrees shifted from the base cutting position.

(2) Vertical cutting position

The “vertical cutting position” is the state the B-axis is shifted 90 degrees from the base cutting position in the positive direction. In this position, the tool attached faces the X-axis direction.

(3) ATC position

MACTURN and MULTUS series are generally equipped with an ATC. To mount a tool to the turret using an ATC, the saddle must be moved to the position where the tool can be replaced, and the turret must be indexed to the ATC position in advance. On MACTURN and MULTUS series machines, the ATC position and the turret indexing angle to the base cutting position are the same. Although physical turret indexing is the same, the control mode may be different.

2-2. Turret Number Assignment

A general turret, for example an octagonal turret, is indexed with index numbers 1 to 8. The turret for MACTURN and MULTUS series machines, on the other hand, can use a single tool in two different indexing positions, which means both the H1 turrets are internally controlled as square turrets in the NC. With a regular turret indexing command (such as T0100 and T0300), the turret number NC has internally assigned will be indexed to the base cutting position.

H1 turret numbers Although only one tool can be attached to the H1 turret, turret numbers 1 to 3 are assigned to it. The turret can, therefore, be indexed as shown below with a T command, but to which direction the tool will be faced will generally be directed.

5262-E P-3

SECTION 1 TURRET OPERATION

LE32114R0400300040001

2-3. Turret Indexing Turret Control

The H1 turret cannot make a full turn because of the structure of the turret, and moves like a turret within a specific range as shown below. In a machine with a turret indexing single-direction positioning function (*) for turret control, an error will occur if an overshoot in a single direction is in the turret indexing prohibition range.

* Such a machine positions the B-axis from the B-axis negative direction to the positive direction,

irrespective of the position of the target point. With a command of positioning to a smaller angle than the current one, the B-axis will move to -10 degrees and then in the positive direction to the target point.

H1 turret

The MACTURN series can rotate the H1 turret between -15° and +195° and MULTUS series machine can rotate between -30° and +195° with the base cutting position set at 0°. It will be indexed in the order of T1 → T2 → T3 → T2 → T1 → T2... with the manual turret swing button.

3. Turret B-axis Positioning Control

When “B-axis one-degree indexing mode” or “B-axis 1/1000-degree pitch indexing mode” is selected, the B-axis can be positioned to any set angle. This B-axis positioning control function is available for machining inclined faces.

3-1. B-axis Positioning

The B-axis can be positioned with only an MDI command or program command. To perform manual operation with the B-axis positioned, the B-axis must be positioned in advance by MDI operation. For specific B-axis positioning commands, see 5. “Turret B-axis Positioning Commands”.

3-2. Movable Range of the B-axis

In B-axis positioning, the angular reference for the B-axis angle command is different depending on the turret Indexed state. Basically, the increment in the B-axis angle from the turret indexing position as the reference is directed. Depending on the turret indexing position, an error will occur if he B-axis positioning angle is out of the movable range. Set the movable range with the mechanical system parameters “turret boundary angle” and “turret angle range.”

5262-E P-5

SECTION 1 TURRET OPERATION

H1 turret

Assuming that the indexed angle of the B-axis with T1 as the base cutting position is 0.000°, the Baxis positioning command range for MACTURN series is between -30° and +195° and MULTUS series is -30° and +195°.

LE32114R0400300080001

LE32114R0400300080002

3-3. Precautions for B-axis positioning control

(1) The B-axis positioning data just after software installation is 0 degrees.

(2) Issue a B-axis angle data command in the “BA=” format.

(3) A B-axis positioning command must be set in the same block as a turret indexing command.

(4) “BA = 0” will be considered directed when only a turret indexing command is issued.

(5) After the operation mode is switched from automatic or MFI operation to manual operation, the

angle data for the B-axis positioning command remains valid. The B-axis angle data is backed up in real time and will be retained even after the power is turned OFF.

(6) The B-axis positioning angle data is displayed as current position data. However, if there is a

difference of more than 0.5 degrees between the directed B-axis position and the angle of the B-axis actually positioned, the current position will be displayed as “.” In this case, the current position will be displayed in the normal manner by swinging the turret again.

(7) The direction of the B-axis coordinates generally depends on the direction of the Y-axis coordi-

nates. MACTURN and MULTUS series machines, however, always treat the counterclockwise direction as the B-axis positive direction. This direction will not be affected by Y-axis mirror images that will be described later. On machines equipped with a sub-spindle, the clockwise direction viewed from the turret is the B-axis positive direction when the coordinate system for the second spindle mode is selected.

5-6. Turret Rotary Position Offset Command in B-axis Positioning

(G52)

When performing machining by issuing the BA command after locating the turret in a specified position, regular tool offset is no more effective. The tool edge position must be offset by dividing the edge position into the X direction component and the Z direction component using the turret rotation axis as the center. The T, TL, and OG commands are used to index the turret, but they do not perform tool offset when the B-axis is located in cutting position. To calculate the edge position when the BA command is executed, execute the G52 command. By doing this, the edge position will be internally calculated using various parameters such as turret center offset, edge position offset, turret number, and tool offset, allowing you to set correct offset positions.

(1) Okuma reference point

The offset reference point is factory-set at the point where the motor rotary axis intersects with the motor end face when the B-axis angle is set to 0°.

(2) Turret center offset

The positional relation between the Okuma reference point and the turret rotation center can be set. Normally, this offset is already set before a machine is shipped. This value affects the calculation of the turret rotary position offset command.

(3) Edge position offset

The offset from the Okuma reference point to the user reference point set by a user can be set.

6. Manual Turret Indexing Operation

Although the turret for MACTURN and MULTUS series machines is the H1 turret in appearance, it is internally controlled so that 90-degree indexing is possible. For turrets that are not designed to continuously swing due to the structure of the turret, turret control is performed instead.

6-1. Turret Indexing Position

There are three turret indexing positions: the base cutting position, the vertical cutting position, and the ATC position. On MACTURN and MULTUS series machines, the base cutting position and the ATC position are identical, but because the purpose of operation is different between them, for which purpose indexing will be performed must be selected with “turret indexing” on the ATC operation panel.

6-2. H1 Turret

The H1 turret cannot continuously swing. For this reason, the order of indexing to the cutting position is as shown below. Additionally, since only one tool can be attached to the turret, the turret does not operate even if the turret swing button is pressed after the tool has been indexed to the ATC position as long as “ATC position” indexing is selected.

5262-E P-15

SECTION 1 TURRET OPERATION

6-2-1. Indexing the turret to the cutting position

The turret is indexed in the order shown below. However, when the B-axis positioning command (BA command) is set, the axis will be positioned to the position offset by the angle.

6-2-2. Indexing the turret to the ATC position

T1 is indexed directly to the ATC position, irrespective of the indexed state of the turret. However, by clicking the turret button in the state of T3, the turret suspends swinging in the state of T2. Holding down the button indexes the turret directly to the ATC position.

6-2-3. Turret swing conditions

LE32114R0400300310001

• Either the X-axis or Z-axis is positioned on the positive variable limit.

• On a machine equipped with a sub-spindle, the X-axis is positioned on the positive variable

limit.

• The saddle is positioned in the ATC tool replacement position.

The turret can swing when any one of the above conditions is met.

7. Manual B-axis Positioning Operation

When the “B-axis one-degree pitch indexing” function or “B-axis 1/1000-degree pitch indexing” function is selected, the turret swing can be not only positioned but also positioned as the B-axis. This section describes B-axis positioning. Since only the difference between one-degree pitch indexing function and 1/1000-degree pitch indexing is the minimum command unit, note that only the command values must be replaced with the appropriate ones when reading the text.

7-1. Positioning the B-axis

The B-axis cannot be positioned in manual operation. To position it in a specific position, executed the BA command in advance in MDI operation mode or automatic operation mode. Once the BA command has been executed, it remains valid until the next command is executed. It will be kept stored even if the machine is reset or the power is turned OFF. The issued BA command pairs up with a turret number. To index the turret for which the BA command has been executed when the turret swing button is pressed in manual operation mode, the turret will be positioned to the position the BA command is reflected. B-axis positioning described above cannot be performed until “cutting position” is selected for turret indexing on the ATC operation panel.

5262-E P-16

SECTION 1 TURRET OPERATION

7-2. Canceling B-axis positioning

To cancel B-axis positioning in manual turret indexing, index the turret to the base cutting position or vertical cutting position in MDI operation mode or automatic operation mode. When no BA command is attached, [BA = 0] is considered in the NC directed and the B-axis angle data is deemed cleared.

7-3. BA Angle Data Display

The BA data after B-axis positioning will be displayed as [BA] of the current position. When the Baxis one-degree pitch indexing function is used, decimals are not displayed. If there is a difference between the BA command and the actual B-axis positioning angle, **** (asterisks) will be displayed.

It is possible to feed the saddle in slanted directions (X-axis - Z-axis contouring) by manual pulse handle feed or JOG feed.

8-1. Designating a Slant Feed Direction

Procedure :

1 Select parameter setting mode.

2 Using [DISPLAY CHANGE], [ITEM], etc., have the “B-AXIS USER PARAMETER” screen dis-

played.

8-2. Selecting Slant Feed, Feed Operation

To perform slant feed by manual operation, the “SLANT FEED” key on the auxiliary operation panel to select slant feed mode. During slant feed selection, the LED on the panel remains lit. During slant feed selection, the X-axis feed key and the Z-axis feed key are available, or pulse hand X-axis/Y-axis selection becomes valid for the X’-axis and the Z’-axis. Other operations relating to the Y-axis and the C-axis are the same as the regular operations.

[Supplement]

• If two or more of the X-axis, Y-axis, Z-axis, and C-axis JOG keys on the operation panel are

pressed at the same time when the “SLANT FEED” LED is lit, none of all of the feed axes will move.

• Slant feed can be selected only in “manual operation mode or manual intervention mode” and

“Y-axis control mode.”

(1) Manual slant feed speed, slant feed distance

Manual slant feed using the JOG keys is performed at the X-axis or Z-axis manual feed unit rate set in the axis data file, whichever is slower. The manual feed acceleration unit rate increases or decreases with the manual feed acceleration unit rate for the axis whose manual feed unit rate has been adopted. The feed distance in pulse handle feed is the travel distance in the manual slant feed direction designated by the pulse handle. During slant feed selection, the Y-axis command is a radius value command as Y-axis control mode is selected.

(2) Control when the axis has reached the variable limit

The X-axis or Z-axis setting position is valid as the variable limit even during manual slant feed selection. When either the X-axis or Z-axis, which is in manual slant feed in the X’-axis or Z’axis, has reached the variable limit, all axis feed operations will stop, and the X’-axis or Z’-axis will not move in the direction beyond the variable limit.

5262-E P-20

SECTION 1 TURRET OPERATION

8-3. Caution on Recovering from Manual Intervention

[Supplement]

If slant feed is performed and the SEQUENCE RETURN key is pressed during manual intervention, the X-axis and the Y-axis independently travel to the sequence restart position and will not linearly move back in the slant feed direction. Each axis returns at the manual feed speed. Before pressing the SEQUENCE RESTART key, move the axes closer to the return position in advance to minimize the axis travel distance to return.

8-4. Relationship with the Slant Compound Fixed Cycle Function

The slant angle command value, which is issued simultaneously with the slant machining mode ON command (G127), is automatically set in “SLANT FEED ANGLE” on the B-AXIS USER PARAMETER screen. Before manually using the slant feed function, confirm that the feed angle set in “SLANT FEED ANGLE” is the appropriate value.

8-5. Others

Since the turret B-axis positioning angle and the coordinate conversion angle around the Y-axis specified in “SLANT FEED ANGLE” are independently handled, pay attention to both angle data when drilling a slant face.

SECTION 1 TURRET OPERATION

9. Tool Index Function

The H1 turret for MACTURN and MULTUS series machines has the same attachment structure for both cutting tools and rotary tools. The edge of even a cutting tool can be set at any desired angle by means of an M-axis indexing function. Making effective use of this structure and turning the edge 180 degrees make it possible to use tool for other purposes. The tool index function is intended to index a tool and select its data.

9-3. Relation between Tool Index Command and Tool Compensation

When a tool index command is specified, the graphic display of the tool shape changes automatically. However, the tool compensation data is not changed. It is, therefore, necessary to specify the tool compensation data again after indexing the tool. Description below is the mechanism of a machine equipped with a “tool compensation multi-system function.” A machine equipped with a tool compensation multi-system function has a tool compensation data table for each of the base position, the vertical position and positions A/B (a machine having a subspindle has eight data tables in all). Upon execution of a tool index command, the tool offset, nose R compensation, and nose R compensation direction numbers switch to those shown in the opposite position table. That is, each compensation number remains unchanged, but the compensation values specified by these compensation numbers are changed as the table itself is changed.

Position A

Tool offset

Nose R compensation

Nose R direction

For example, when the dot-meshed compensation of No. 2 is selected in position A, the compensation switches to No. 2 in the table under Position B upon execution of tool indexing. Since the tables are independent, the compensation values are different between them.

The following M codes are used to index an M-tool spindle: M602: Command for indexing the M-tool spindle at 0° position and clamping it. M603: Command for indexing the M-tool spindle at 180° position and clamping it.

Position B

LE32114R0400300470001

9-5. Relation between Rotary Tool and Tool Index Commands

The tool index command can be specified even if a rotary tool is mounted. Since the rotary tool can be used for turning as well as milling, it is necessary to specify the tool index command according to the purpose of use. As described in 9-3. “Relation between Tool Index Command and Tool Compensation”, if the tool offset multi-system is provided, the tool offset table changes upon designation of a tool index command even when using a rotary tool for milling. Set the tool offset data used only for milling in position A, and after specifying the tool index command, return the tool to position A before performing milling.

10. Parameter Settings

Setting range : -9999.999 to 9999.999

Initial value : 0.000

10-2. B-axis System Parameters

5262-E P-23

SECTION 1 TURRET OPERATION

(1) Turret center offset

The positional relation between the Okuma reference point and the turret rotation center can be set. Normally, this offset is already set before a machine is shipped.

Setting unit : 1 mm

Setting range : -9999.999 to 9999.999

Initial value : 0.000

10-3. Turret Position Error Compensation

Turret position error compensation in the reference cutting position is the same as general turret position error compensation. However, turret position error compensation in the vertical cutting position becomes valid only when the “B-axis one-degree pitch indexing function” and the “B-axis 1/ 1000-degree pitch indexing function” are not provided. The turret compensation number is selected based on only the turret number. For example, the compensation value for “turret No. 2 in the vertical cutting position” is used for the turret position error compensation value for machining with the tool attached to turret No. 1 in the vertical cutting position.

Setting unit : 1 mm

Setting range : -9999.999 - 9999.999

Initial value : 0.000

10-4. B-axis Indexing Angles

This parameter is displayed only when the B-axis one-degree pitch indexing function is selected. Set the indexing position of each B-axis corresponding to the B-axis positioning command.

Setting unit : 0.001 degrees

Setting range : 0.000 degrees - 359.000 degrees

Initial value : Set for each point according to the following rule:

Initial value = (Point number - 1) x 1.000 degree

10-5. M-axis Orientation

This parameter becomes valid only when the M-axis fixed position stop function and the B-axis control function are selected. Set M-axis orientation when the M-axis is indexed to the base cutting position, and that when it is indexed to the ATC position for each turret number.

Setting unit : 1 degree

Setting range : 0.000 - 359.999

Initial value : 0.000

10-6. System Parameters

When the machine is equipped with an H1 turret and an inductosyn detection function or pitch error compensation function, the following “origin offset” parameter will be added to the system parameter T-axis. Detector offset, backlash, in-position, detector, and connection compensation are the same as the regular parameters.

(1) Origin offset

This parameter is used to compensate for the detector offset when it is not 0.000 degrees due to Inductosyn connection or for some other reason although the offset was set so that the mechanical coordinates would be 0.000 degrees by indexing turret No. 1 to the base cutting position.

Setting unit : 1 degree

Setting range : -0.999 - +0.999

Initial value : 0.000

5262-E P-24

SECTION 1 TURRET OPERATION

10-7. Optional Parameters

This parameter becomes valid when the tool compensation multi-system function is selected.

(1) Vertical position command SP

This parameter enables a machine with the tool compensation multi-system function to switch the tool compensation table to be used according to the turret indexing state (for base position and vertical position). On a machine equipped with a B-axis positioning function, the physical state of the turret is the same when base cutting position indexing BA = 90 is executed and when vertical position indexing is performed. However, the tool compensation data of the table for the base position is used for the former, and that of the table for the vertical position for the latter. With this parameter, whether base position or vertical position tool compensation will be used when base cutting position indexing BA = 90 is executed can be selected.

INVALID : The base position tool compensation data will be used.

EFFECT : The vertical position tool compensation data will be used.

Initial value : INVALID

(2) Tool offset automatic calculation

A machine with the tool compensation multi-system function has a tool compensation table for each system. However, it uses the same tools in principle, and it is, therefore, possible to roughly calculate the tool offset data on the other tools by internal operation if the tool offset data on any one of the tools is obtained. This automatic calculation function becomes valid at tool offset measurement with a touch sensor. Automatic calculation will not be performed in manually setting, adding or calculating the tool offset. With this parameter, whether the data on other systems will be automatically calculated can be selected.

INVALID : Automatic calculation will not be performed.

EFFECT : Automatic calculation will be performed.

Initial value : EFFECT

This parameter sets the turret index prohibition area in turret index control. The turret index prohibition area is specified with the angle position of the boundary the turret must not enter and the angle width of the prohibition area. To disable turret index control, set “0.000” in the field of “Turret index prohibition width.”

(1) Turret index boundary angle

Set the negative side angle of the prohibition area.

Setting unit : 1 degree

Setting range : 0.000 - 359.999

Initial value : 0.000

(2) Turret index prohibition width

Set the angle width that defines the boundary the turret must not enter.

Setting unit : 1 degree

Setting range : 0.000 - 359.999

Initial value : 0.000

11. Tool Data Setting

11-1. Tool Shape Data

The TOOL SHAPE screen displayed in tool data setting mode is used to set the graphic data on the tools to be used for machining simulation. The B-axis control turret is indexed to the base cutting position and the vertical cutting position and thereby ensures machining in two ways. The tool shape data is set for the base cutting position and for the vertical cutting position, and the data is switched according to the command.

(1) Setting the tool shape data

For how to set tool shape data, see the operation manual as the procedure is the same as the standard setting. To display the base cutting position tool shape screen or vertical cutting position tool shape screen, press the function key [F4] (CUTTING POSITION). Each time the function key is pressed, [BASE] and [VERTICAL] are switched alternately.

11-2. Tool Compensation

This section describes the basic concept of tool compensation on MACTURN and MULTUS series machines. As shown in the figures below, the table of tool offset, nose R compensation, and nose R direction is common to base cutting position and vertical cutting position indexing. For this reason, the same tool compensation number cannot be used for base cutting position indexing and vertical cutting position indexing. Although “base position” and “vertical position” tool shape codes are available for graphic drawing, tool shape data is shared.

11-3. Tool Life Management (Special Function)

The OG command issued by the tool life management function is to specify which number of tool compensation value in the tool compensation group set for the tool in tool data setting mode to use. Some tools attached to the H1 turret machines perform cutting in both the base cutting position and the vertical cutting position, but the same tool compensation number cannot be used for two cutting positions because the edge positions are different. The tool group number and offset group number for tool life management can, therefore, be used for the “base position” and the “vertical position” respectively. A tool information table for tool life management is available for each cutting position, and three sets of offset group numbers can be selected as in general tool life management.

Press the function key [F4] (CUTTING POSITION) on the second page of functions to switch the tool life management table for the base cutting position or vertical cutting position.

SECTION 1 TURRET OPERATION

12. Tool Compensation Multi-System Function

A table containing general information about tools (compensation data, shape data) is prepared base on the turret. So, the same offset number cannot be used when tools having two or more coordinate systems, such as sub-spindles, are used or when the same tool is used for different indexing operations like MACTURN and MULTUS series machines. The tool compensation multi-system function divides the purposes of use of tools in a systematic manner and makes independent offset numbers available for each system.

12-1. Combinations of Compensation Systems

The following are the functions that are available for system combinations according to the purposes of use of tools:

• H1 turret function

• Tool compensation multi-system function

• Tool index function

This manual describes the sub-spindle model because it covers all the machine models. In the case of single spindle model, regard it as the machine equipped only with the first spindle.

In the following table, the dot-shaded fields show a table. For example, if the dot-shaded field on the line of tool offset, nose R compensation, and nose R direction is across the columns of first spindle base position, first spindle vertical position, second spindle vertical position, and second spindle base position, the tool compensation table is shared by the systems. Divided dot-shaded fields on the same line indicate that different tables are used for the systems.

“Position A” and “Position B” in the tables above are position A and position B of the tool index function. “A/B automatic switching” in the tables means that the shape code automatically changes when position A or position B is switched to the other by tool indexing.

* By selecting the tool compensation multi-system control function, the handling of the tool group

and offset group greatly varies between tool compensation (tool offset, nose R compensation, nose R direction) and tool life management. An independent compensation table for tool compensation is provided for each system, whereas the information tables for tool life management are common to the systems. However, the tool compensation data indirectly connected by an offset group is independently available for each system, and it does not actually cause any problem in common information tables.

12-4. Tool Life Management Tool Information Screen for the Tool Com-

pensation Multi-system Function

There are three tool life management information screens: A (number of workpieces machined), B (machining time), and C (wear amount). Each information screen is common to all systems.

12-5. System Variables

When the tool compensation multi-system function is selected, it means that there are two or more tool compensation tables. Up to eight tool compensation tables exist, including machines equipped with a sub-spindle and the tool index function. System variables are available for each system to refer to or set compensation data for each system from the program.

13. Other Functions

13-1. Tool Compensation Automatic Calculation Function

A machine with the tool compensation multi-system function has a tool compensation table for each system. However, it uses the same tools in principle, and it is, therefore, possible to roughly calculate the tool offset data on the other tools by internal operation if the tool offset data on any one of the tools is obtained. This automatic calculation function is applicable to the data on the tool number in the field (tool offset or nose R compensation (including compensation direction)) in which the cursor is placed. The tool compensation system currently selected is the basis for calculation. Pressing the function key [AUTO CAL] activates the automatic calculation function.

13-2. Turret Coolant Interlock

The turret coolant can be output only when the turret is performing cutting position indexing. When the turret is performing ATC position indexing or has not completed indexing, it will not be output even if the coolant operation switch on the operation panel is turned ON. Perform a coolant operation after cutting position indexing has been completed. Additionally, the turret coolant will not be output as long as the shutter of the ATC is open.

5262-E P-34

13-3. Data Input/Output Function

The H1 turret machine switches base position indexing or vertical position indexing to the other according to the purpose, and has a tool compensation table for each system. The tool compensation data structure is different depending on whether the “tool compensation multi-system control function” is selected. The following table summarizes the data structures. For the operation of the data input/output function, see the “Operation Manual.” The data input/output procedure for turret B of a two-saddle machine is the same as general data input/output. See the “Operation Manual.”
