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 maximum 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.
5262-E P-(iv)
SAFETY PRECAUTIONS
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
(1)Keep the vicinity of the machine clean and tidy.
(2)Wear appropriate clothing while working, and follow the instructions of someone with sufficient training.
(3)Make sure that your clothes and hair cannot become entangled in the machine. Machine operators must wear safety equipment such as safety shoes and goggles.
(4)Machine operators must read the instruction manual carefully and make sure of the correct procedure before operating the machine.
(5)Memorize the position of the emergency stop button so that you can press it immediately at any time and from any position.
(6)Do not access the inside of the control panel, transformer, motor, etc., since they contain highvoltage terminals and other components which are extremely dangerous.
(7)If two or more persons must work together, establish signals so that they can communicate to confirm safety before proceeding to each new step.

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.

SECTION 1 TURRET OPERATION
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.

SECTION 1 TURRET OPERATION
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.

SECTION 1 TURRET OPERATION
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.”
H1 turret
Assuming that the indexed angle of the B-axis with T1 as the base cutting position is 0.000°, the B- axis positioning command range for MACTURN series is between -30° and +195° and MULTUS series is -30° and +195°.

SECTION 1 TURRET OPERATION
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 coordinates. 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.

In general, the tool compensation number, nose R compensation number or tool diameter compensation number is specified by setting the compensation number together with a turret indexing command. However, by using this function, these compensation numbers can independently be set without using a turret indexing command.
[Command format]
OF = oo
OF = ooo Number of tool life control sets: 200
This command can change the currently valid tool compensation number or nose R compensation number.
•An error will occur if the OF command is set in the same block as the T, TL, and OG commands.

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.
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
•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.
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.
