SAFETY PRECAUTIONS

Preface

Safety precautions relating to the CNC unit (in the remainder of this manual, referred to simply as the NC unit) that is provided in this machine are explained below. Not only the persons who create programs, but also those who operate the machine must thoroughly understand the contents of this manual to ensure safe operation of the machine.

Read all these safety precautions, even if your NC model does not have the corresponding functions or optional units and a part of the precautions do not apply.

Rule

1. This section contains the precautions to be observed as to the working methods and states usually expected. Of course, however, unexpected operations and/or unexpected working states may take place at the user site. During daily operation of the machine, therefore, the user must pay extra careful attention to its own working safety as well as to observe the precautions described bel ow.

2. Although this manual contains as great an amount of information as it can, since it is not rare for the user to perform the operations that overstep the manufacturer-assumed ones, not all of “what the user cannot perform” or “what the user must not perform” can be fully covered in this manual with all such operations taken into consideration beforehand. It is to be understood, therefore, that functions not clearly written as “executable” are “inexecutable” functions.

SAFETY PRECAUTIONS

3. The meanings of our safety precautions to DANGER, WARNING, and CAUTION are as follows:

: Failure to follow these instructions could result in loss of life.

DANGER

: Failure to observe these instructions could result in serious harm to a human

life or body.

WARNING

: Failure to observe these instructions could result in minor injuries or serious

machine damage.

CAUTION

Basics

SAFETY PRECAUTIONS

! After turning power on, keep hands away from the keys, buttons, or switches of the

operating panel until an initial display has been made.

WARNING

! Before proceeding to the next operations, fully check that correct data has been entered

and/or set. If the operator performs operations without being aware of data errors, unexpected operation of the machine will result.

! Before machining workpieces, perform operational tests and make sure that the machine

operates correctly. No workpieces must be machined without confirmation of normal operation. Closely check the accuracy of programs by executing override, single-block, and other functions or by operating the machine at no load. Also, fully utilize tool path check, Virtual Machining, and other functions, if provided.

! Make sure that the appropriate feed rate and rotational speed are designated for the

particular machining requirements. Always understand that since the maximum usable fee d rate and rotational speed are determined by the specifications of the tool to be used, those of the workpiece to be machined, and various other factors, actual capabilities differ from the machine specifications listed in this manual. If an inappropriate feed rate or rotational speed is designated, the workpiece or the tool may abruptly move out from the machine.

! Before executing correction functions, fully check that the direction and amount of

correction are correct. Unexpected operation of the machine will result if a correction function is executed without its thorough understanding.

! Parameters are set to the optimum standard machining conditions prior to shipping of the

machine from the factory. In principle, these settings should not be modified. If it becomes absolutely necessary to modify the settings, perform modifications only after thoroughly understanding the functions of the corresponding parameters. Modifications usually affect any program. Unexpected operation of the machine will result if the settings are modified without a thorough understanding.

Remarks on the cutting conditions recommended by the NC

! Before using the following cutting conditions:

- Cutting conditions that are the result of the MAZATROL Automatic Cutting Conditions

WARNING

Determination Function

- Cutting conditions suggested by the Machining Navigation Function

- Cutting conditions for tools that are suggested to be used by the Machining Navigation

Function

Confirm that every necessary precaution in regards to safe machine setup has been taken – especially for workpiece fixturing/clamping and tool setup.

! Confirm that the machine door is securely closed before starting machining.

Failure to confirm safe machine setup may result in serious injury or death.

S-2

Programming

WARNING

SAFETY PRECAUTIONS

! Fully check that the settings of the coordinate systems are correct. Even if the designated

program data is correct, errors in the system settings may cause the machine to operate in unexpected places and the workpiece to abruptly move out from the machine in the event of contact with the tool.

! During surface velocity hold control, as the current workpiece coordinates of the surface

velocity hold control axes approach zeroes, the spindle speed increases significantly. For the lathe, the workpiece may even come off if the chucking force decreases. Safety speed limits must therefore be observed when designating spindle speeds.

! Even after inch/metric system selection, the units of the programs, tool information, or

parameters that have been registered until that time are not converted. Fully check these data units before operating the machine. If the machine is operated without checks being performed, even existing correct programs may cause the machine to operate differently from the way it did before.

! If a program is executed that includes the absolute data commands and relative data

commands taken in the reverse of their original meaning, totally unexpected operation of the machine will result. Recheck the command scheme before executing programs.

! If an incorrect plane selection command is issued for a machine action such as arc

interpolation or fixed-cycle machining, the tool may collide with the workpiece or part of the machine since the motions of the control axes assumed and those of actual ones will be interchanged. (This precaution applies only to NC units provided with EIA functions.)

! The mirror image, if made valid, changes subsequent machine actions significantly. Use

the mirror image function only after thoroughly understanding the above. (This precaution applies only to NC units provided with EIA functions.)

! If machine coordinate system commands or reference position returning commands are

issued with a correction function remaining made valid, correction may become invalid temporarily. If this is not thoroughly understood, the machine may appear as if it would operate against the expectations of the operator. Execute the above commands only after making the corresponding correction function invalid. (This precaution applies only to NC units provided with EIA functions.)

! The barrier function performs interference checks based on designated tool data. Enter the

tool information that matches the tools to be actually used. Otherwise, the barrier function will not work correctly.

! The system of G-code and M-code commands differs, especially for turning, between the

machines of INTEGREX e-Series and the other turning machines. Issuance of the wrong G-code or M-code command results in totally non-intended machine operation. Thoroughly understand the system of G-code and M-code commands before using this system.

Sample program Machines of INTEGREX e-Series Turning machines

S1000M3 S1000M203

The milling spindle rotates at 1000 min–1. The turning spindle rotates at 1000 min–1. The turning spindle rotates at 1000 min–1. The milling spindle rotates at 1000 min–1.

S-3

SAFETY PRECAUTIONS

! For the machines of INTEGREX e-Series, programmed coordinates can be rotated using

an index unit of the MAZATROL program and a G68 command (coordinate rotate command) of the EIA program. However, for example, when the B-axis is rotated through 180 degrees around the Y-axis to implement machining with the turning spindle No. 2, the plus side of the X-axis in the programmed coordinate system faces downward and if the program is created ignoring this fact, the resulting movement of the tool to unexpected positions may incite collisions. To create the program with the plus side of the X-axis oriented in an upward direction, use the mirror function of the WPC shift unit or the mirror imaging function of G-code command (G50.1, G51.1).

! After modifying the tool data specified in the program, be sure to perform the tool path

check function, the Virtual Machining function, and other functions, and confirm that the program operates properly. The modification of tool data may cause even a field-proven machining program to change in operational status. If the user operates the machine without being aware of any changes in program status, interference with the workpiece could arise from unexpected operation. For example, if the cutting edge of the tool during the start of automatic operation is present inside the clearance-including blank (unmachined workpiece) specified in the common unit of the MAZATROL program, care is required since the tool will directly move from that position to the approach point because of no obstructions being judged to be present on this path. For this reason, before starting automatic operation, make sure that the cutting edge of the tool during the start of automatic operation is present outside the clearance-including workpiece specified in the common unit of the MAZATROL program.

CAUTION

! If axis-by-axis independent positioning is selected and simultaneously rapid feed selected

for each axis, movements to the ending point will not usually become linear. Before using these functions, therefore, make sure that no obstructions are present on the path.

S-4

Operations

WARNING

SAFETY PRECAUTIONS

! Single-block, feed hold, and override functions can be made invalid using system variables

#3003 and #3004. Execution of this means the important modification that makes the corresponding operations invalid. Before using these variables, therefore, give thorough notification to related persons. Also, the operator must check the settings of the system variables before starting the above operations.

! If manual intervention during automatic operation, machine locking, the mirror image

function, or other functions are executed, the workpiece coordinate systems will usually be shifted. When making machine restart after manual intervention, machine locking, the mirror image function, or other functions, consider the resulting amounts of shift and take the appropriate measures. If operation is restarted without any appropriate measures being taken, collision with the tool or workpiece may occur.

! Use the dry run function to check the machine for normal operation at no load. Since the

feed rate at this time becomes a dry run rate different from the program-designated feed rate, the axes may move at a feed rate higher than the programmed value.

! After operation has been stopped temporarily and insertion, deletion, updating, or other

commands executed for the active program, unexpected operation of the machine may result if that program is restarted. No such commands should, in principle, be issued fo r the active program.

CAUTION

! During manual operation, fully check the directions and speeds of axial movement. ! For a machine that requires manual homing, perform manual homing operations after

turning power on. Since the software-controlled stroke limits will remain ineffective until manual homing is completed, the machine will not stop even if it oversteps the limit area. As a result, serious machine damage will result.

! Do not designate an incorrect pulse multiplier when performing manual pulse handle feed

operations. If the multiplier is set to 1000 times and the handle operated inadvertently, axial movement will become faster than that expected.

S-5

1 INTRODUCTION

Three-dimensional machining functions are automatic programming functions used for 3dimensional curved-surface machining which presents difficulties for line- or face-machining programs.

Automatic programming functions in the easy-to-understand MAZATROL language (human language) enable 3-dimensional curved surfaces to be machined by performing simple operations.

This Programming Manual describes the programming procedures for machining 3-D curved surfaces with the MAZATROL MATRIX.

Read through this manual carefully in order to make the most of the 3-D machining functions available with the MAZATROL MATRIX.

In addition to this manual, reference should also be made to the Programming Manual and the Operating Manual.

1 INTRODUCTION

- NOTE -

1-2

2 GENERAL

2-1 General

The 3-dimensional machining functions enable 3-dimensional curved surfaces, which are difficult to machine with line- or face-machining programs, to be handled with relative ease.

Programs with a greater degree of flexibility can be prepared when these functions are used in conjunction with the line- and face-machining units.

The features of these 3-D machining functions are listed below:

1. Easy-to-understand MAZATROL language Programming uses the MAZATROL language which allows programs to be created with the same kind of ease which characterizes ordinary MAZATROL programs. As a result, 3-D programming, which presented difficulties before, can now be handled with ease.

2. Simple representation of curved surfaces Wire-frame models that can be defined with figure lines and guide lines are used so that the 3-dimensional curved surfaces can be set as easily as possible. In addition, GL (guide line) and FL (figure line) figures can be input using methods similar to those for line- or facemachining.

GENERAL 2

3. Creation of wide variety of curved surfaces A wide variety of complex curved surfaces can be handled by selecting any of the 11 types of units in accordance with the curved surface to be machined.

4. Automatic determination of tool paths for rough machining and finish machining Simply by defining the final curved-surface figures, the tool paths for both rough machining and finish machining can be determined automatically.

5. Outstanding graphic check functions Not merely the tool path and trace display but also the defined curved-surface figures can be displayed in wire-frame format, and this makes it easier to understand and check the defined curved-surface figures.

2-2 Creation of Curved-Surface Figures

A curved surface is formed when a curved line on a given plane is moved through 3-dimensional space.

A variety of curved-surface figures can be created by defining the following conditions.

- Movement of a constant curved line

- Movement of a changing curved line

The curved-surface figures thus defined are then shaped with a 3-D machining unit.

2-1

2 GENERAL

2-3 Movement of a Constant Curved Line

The movement of a curved line through 3-dimentional space is restricted to the following.

Rotation Parallel displacement Normal displacement

Furthermore, a curved-surface figure can be created by smoothly connecting a multiple number of curved lines on given planeｓ within 3-dimensional space (ruled surface).

2-4 Changing Conditions of a Curved Line

A curved line that is moved through 3-dimensional space is referred to as the FL (figure line). Usually, one FL is defined as the starting curved line or two FLs are defined as the starting and ending curved lines. A GL (guide line) which is used to guide the defined FL is also defined.

The desired curved-surface figure is created by moving and changing the starting figure line (FL1) into the ending figure line (FL2) according to the above conditions and the guid e line (GL).

The X-Z plane moves in the Y-axis direction. (In this case, the reference plane moves 50 mm in the positive direction.)

Note: These distance data have the same significance as those of SHIFT-X, SHIFT-Y and

SHIFT-Z (in [5]). This can be better understood by first setting 0 as the DISTANCE data

and then moving the plane in parallel using the

SHIFT-X/Y/Z.

4. ROT.-X, ROT.-Y, ROT.-Z

Set the angle of inclination of the plane containing the curved line with respect to the base plane as the angle of rotation around the axis in question. In accordance with this angle, the reference plane rotates around the designated axis as its center. (Set 0 for an axis around which no rotation is intended.)

In this case, the reference plane rotates 30° counterclockwise (po sitive value) a round the X-axis.

Note 1: The rotational direction around each axis must be designated with a positive value for

counterclockwise rotation when viewed from the positive (+) side of the rotating axis. For clockwise rotation, set a negative value.

Note 2: If rotational angles are set for a multiple number of axes, the reference plane will rotate

around the axes in the order of X, Y and Z.

5. SHIFT-X, SHIFT-Y, SHIFT-Z

Set the distance between the plane containing the curved line and the reference plane. The reference plane now moves in parallel with the specified axis. (Set 0 for an axis along which no movement is intended.)

4-9-1 Coordinate axes for defining FL in NORMAL units

In NORMAL units, the direction of the coordinate axes used to define figure lines (FLs) differs according to the direction of the guide line (GL).

With a change of the coordinate axes, the coordinates of the figure lines (FLs) cha nge eve n if the FLs appear to be the same. Proceed carefully with the programming so that they will not be confused with those for other units.

1. Selection of coordinate axes

The coordinate axes are selected here using the left-hand rule. This method is directly related to the movement direction of the guide line (GL) and the plane on which GL is defined, and so each axis and its direction (+, –) can be fixed.
