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 below.

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.

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

SAFETY PRECAUTIONS

Basics

! 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, solid check, 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 feed 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 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.

SAFETY PRECAUTIONS

Programming

!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. (This precaution applies only to the M640MT/MT 5X/T/T NEXUS/TN and M640M Pro/MT Pro.)

!The system of G-code and M-code commands differs between the machines equipped with M640M Pro (e-Series such as the INTGEREX e-410, e-650 and e-1060) and the machines equipped with M640MT/MT 5X/T/T NEXUS/TN/MT Pro (such as the INTGEREX non e- Series, the SQT Series, the MPX Series and the QTN Series).

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.

!For the machines equipped with M640M Pro (e-Series such as the INTGEREX e-410, e- 650 and e-1060), 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 solid check 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.

SAFETY PRECAUTIONS

! 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.

CAUTION

!If the machine employs sliding surface structure, lubrication may prove to be insufficient during continuous microfeed machining (see Note 1 below), and in the worst case, seizure of the sliding surface could result. For these reasons, the sliding surface needs to be maintained in a well-lubricated condition during such machining by, for example, inserting an oil-film forming program (see Note 2 below).

List of applicable models and intended axes (Models that employ sliding surface structure)

For further details and more specific examples, refer to the relevant Machine Operating Manual, Part 4, Section 1-2, “Precautions for Microfeed Machining (Models that Employ Sliding Surface Structure)”.

Note 1: Continuous microfeed machining refers to the operation in which the movement of the intended feed axis through strokes shorter than those required for lubrication is continuously repeated.

Note 2: The oil-film forming program refers to a program that creates an oil film on the sliding surface by moving the intended machining axis over a long stroke during machining.

SAFETY PRECAUTIONS

Operations

!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 for the active program.

!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 100 times and the handle operated inadvertently, axial movement will become faster than that expected.

OPERATIONAL WARRANTY FOR THE NC UNIT

The warranty of the manufacturer does not cover any trouble arising if the NC unit is used for its non-intended purpose. Take notice of this when operating the unit.

Examples of the trouble arising if the NC unit is used for its non-intended purpose are listed below.

1.Trouble associated with and caused by the use of any commercially available software products (including user-created ones)

2.Trouble associated with and caused by the use of any Windows operating systems

3.Trouble associated with and caused by the use of any commercially available computer equipment

Operating Environment

1.Ambient temperature

During machine operation: 5° to 40°C (41° to 104°F)

Note: When power is turned on, if the thermal sensor detects an ambient temperature under 5°C, the hard disk warm-up status indicator lamp will light up and the NC unit will not start operating at once. After automatic heating of the hard disk by its internal heater, the lamp will go out and the NC unit will start. It takes about 20 minutes for temperature to increase from 0 to 5°C in order to avoid condensation due to sudden changes in temperature.

2.Relative humidity

During machine operation: 30 to 75 % (without bedewing)

Note: As humidity increases, insulation deteriorates causing electrical component parts to deteriorate quickly.

Programming in the MAZATROL language uses an interactive method that allows the system to be operated in accordance with the messages displayed on the CRT monitor. Thus, even a user who is to operate the system for the first time can readily create and edit programs.

Carefully read this manual and the Operating Manual to correctly operate the MAZATROL FUSION 640M system and use its capabilities to their maximum.

NOTE:

The MAZATROL FUSION 640M controls the machining center by digital calculation, but it is possible that the machining cannot be performed because of the processing of a calculation error. Before proceeding with automatic operation therefore, do not fail to inspect the path of the tool on the display in order to verify that the machining is being done correctly.

Organization of this manual

The following outlines the organization of this manual:

PART 1

MAZATROL PROGRAMMING

PROCEDURES

Part 1 describes the architecture of MAZATROL programs, coordinate systems, the keys to be used for programming, and simplified programming procedures.

CONTENTS

1 MAZATROL PROGRAM

The machining MAZATROL program of a workpiece consists in principle of the following four units:

1.Common unit

This concerns a unit which is obligatorily entered in the program head. It specifies the common data to a program assembly such as the material, the initial point, the machining of several workpieces, etc.

2.Basic coordinates system unit

Use to specify the value of the coordinates (basic coordinates) of the workpiece zero point in the machine coordinates system.

3.Machining unit

Use to specify the data concerning the machining method and the machining form. The machining unit is available in the following three types:

Moreover, the necessary data are specified in the following two sequences:

1 MAZATROL PROGRAM

4.End unit

Unit created at the end of program.

Also, the following units are entered when necessary.

5.Auxiliary coordinates system unit

Use to specify the auxiliary coordinates system (OFFSET).

6.Special mode unit

There are the following special mode units. It is possible that these units marked with an asterisk

(*) can not be used or executed in certain machine models.

7.Manual program mode unit

This unit is entered to establish a program corresponding to the EIA/ISO program using the G and M codes which permits performing minute movement or a movement other than machining.

8.MMS unit

Automatic measurement of a basic coordinates system (WPC). MMS unit cannot be used for certain machines or will not be performed even if programmed.

2 SYSTEM OF COORDINATES

In the preparation of the program, a system of coordinates is used for introducing the position of the machining and the form of the machining.

The system of coordinates of the machining center consists of three axes of coordinates which each cross the reference zero point at right angles.

An arbitrary point found in this system of coordinates can be defined by the value of the coordinates in the 3 axes (X, Y and Z).

There are two types of systems of coordinates:

—Machine coordinates system

—Workpiece coordinates system

Z axis

M3P001

Fig. 2-1 Coordinates system

2-1 Machine Coordinates System

The machine actually moves in its own system of coordinates called the machine coordinates system. A point of reference in this system of coordinates is known as machine zero point.

Generally, the machine coordinates system has the machining zone on the side of the minus (negative) direction from the machine zero point.

Note: The following figure represents the case of vertical machining center.

Table

NM210-00510

Fig. 2-2 Machine coordinates system

2-2 Workpiece Coordinates System

If the program is prepared on the basis of the machine coordinates system, the entering of the machining position and of the form of machining is very complex, tedious and inflexible.

Consequently, a temporary reference point is taken in the machine coodinates system for preparing the program.

The point thus taken is called the workpiece zero point, and the system of coordinates taking this point as reference is called the workpiece coordinates system.

Example:

Plan of the workpiece

M3P002

—When the dimensions are entered of the configuration on the basis of the above plan of the workpiece, the bottom left hand corner is taken as the workpiece zero point.

—In this case, the value of the coordinates of the configuration is the following:

The adoption of the workpiece zero point facilitates the entering of the machining dimensions and therefore the programming.

2-3 Machine Coordinates System and Workpiece Coordinates System

The relationship between the machine coordinates system and workpiece coordinates system when workpiece has been mounted on the table of a machine is shown below.

Machine coordinates system

Machine coordinates system

Machine coordinates system

The machine moves in the machine coordinates system whilst the program is prepared depending on the workpiece coordinates system.

It is necessary therefore to enter in the program, the position relation between the machine coordinates system and the workpiece coordinates system.

The unit of entry is called the basic coordinates unit.

The basic coordinates are entered as values of the coordinates of the workpiece zero point in the machine coordinates system.

The unit of the basic coordinates is entered by utilizing the coordinates measurement function after the workpiece is placed on the machine.

Fig. 2-4 Basic coordinates

Example of entering of the basic coordinates unit:

2-5 Auxiliary Coordinates

The auxiliary coordinates are used for offsetting the workpiece zero point to any position in order to further facilitate the preparation of the program.

The auxiliary coordinates unit (OFFSET) is entered as a value of offsetting in the workpiece zero point.

SYSTEM OF COORDINATES 2

1.Example of entering of auxiliary coordinates

+y0

Workpiece zero point

M3P003

In this example, the entering of the position of hole P1 requires a very complicated calculation.

However, the use of auxiliary coordinates permits performing this entering easily.

+y1

+x1

P1

30°

Zero point offset in auxiliary

coordinates mode

M3P004

As the figure above shows, positions P1 and P2 are entered as follows by offsetting the workpiece zero point to R1.

P1 = (50, 0)

P2 = (50, 20)

In this case, the auxiliary coordinates unit to be programmed is as follows:

2 SYSTEM OF COORDINATES

2.Cancellation of auxiliary coordinates

The system of auxiliary coordinates is voided in the following cases:

A.The system of auxiliary coordinates specified in a sub-program is voided at the time of the return on the main program.

When the main program contains a system of auxiliary coordinates, the return is made to this system of auxiliary coordinates.

B.The system of auxiliary coordinates is voided when a new system of basic coordinates is introduced. In this case, the state without a system of auxiliary coordinates is assumed. (When the system of basic coordinates was specified in the sub-program as shown in Figure 2-5, the return to the main program has the effect of voiding the system of auxiliary coordinates of the main program.)

WPC is a code that signifies the basic coordinates system.

Machining [2] is performed under the coordinates system of WPC-2.

4 PROCEDURE BEFORE PERFORMING THE MACHINING

4-1 Diagram of Preparation for the Machining

To machine a workpiece, it is essential to coordinate the programming and the preparations for the tool and the workpiece. The following diagram shows the general procedure to be followed before performing the machining.

Note 1: It is possible to monitor the path of the tool even if the tool is not recorded in the tool data. (The path of the tool is laid out by taking the diameter of the tool = the nominal diameter and the length of the tool = 0).

Note 2: Automatic operation can not be performed if the tool used is not recorded in the tool data.
