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 m achine 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 cont ains the precautions t o b e obs er ve d as to the working methods and s tates usually expected. Of course, however, unexpec ted operations and/or un expected 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 c ontains as great an amount of information as it can, since it is not rare for the user to perfor m the operations that ov erstep the manufactur er-assumed ones, not all of “what the user ca nnot perform” or “what the us er must not perform” c an 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 obs erve t hese instructi ons could r esult in ser ious harm to a hum an

life or body.

WARNING

: Failure to obs erve these instructions could result in m inor injuries or serious

machine damage.

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 th e next operations, full y check that correct data has b een 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 m ake 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 b y operating the machine at no load. Also, full y 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 spe ed are det er mined by the specificat ions of the to ol to b e us ed , th os e of the workpiece to be m achined, and various ot her factors, actual c apabilities diff er from the machine specif ications listed in this manual. If an inappropriate fee d rate or rotationa l 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.

Param eters are set to the optim um standard m achining conditi ons prior to sh ipping of the

machine from the fac tor y. In princ iple, these settings s houl d not be m odif ied. If it b ecom es absolutely necessary to modify the settings, perform modifications only after thoroughly understanding the func tions of the correspondin g parameters . Modifications us ually aff ect any program. Unexpected oper ation of the machine will resu lt 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

Function

Confirm that every necessary precaution in regards to safe machine setup has been taken – especially for workpiec e fixt uring /c lamping 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

! Full y check that the s ettings of the c oordinate s ystem s are c orrect. Even if th e des ignated

program data is correct, errors i n the s ystem s ettings m a y cause the m ac hine to operate in unexpected places a nd the work piece to abruptl y m ove out fr om the m achine in the e vent of contact with the tool.

! During surface velocit y hold control, as the current work piece coordinates of the surf ace

velocity hold contr ol axes appr oach zeroes , the spind le speed inc reases signif icantly. F or the lathe, the work piece m ay even c om e off if the chuc k ing forc e decreas es. 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 register ed until that t ime are not c onverted. Full y check these data units before operating the machine. If the machine is oper ated without checks being performed, even exis ting correct programs may cause the machine to oper ate 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 r everse of their origin al meaning, totall y 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-cyc le m ac hini ng, the too l may collide with the work piece or part of the machine since the m otions of the control axes assum ed 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 subse quent machine actions si gnificantly. Use

the mirror image f unction only after th oroughly unders tanding the abo ve. (This pr ecaution 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 ex pectations of the oper ator. Execute the above com mands only af ter making the correspondin g correction functio n invalid. (This precaution a pplies only to NC units provided with EIA functio ns .)

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

tool information that m atches the tools t o be actual ly used. Other wise, the barr ier 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 eSeries, 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.

Sample program Machine with M640M Pro

S1000M3 S1000M203

SAFETY PRECAUTIONS

! For the machines equi pped with M640M Pro (e-Ser ies 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 ex ample, when the B-axis is rota ted 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 fac t, the resulting movement of the tool to unexpected posit ions may incite collisions. To create the progr am with the plus sid e of the X - ax is or ie nted in an upward directio n, us e 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 so lid check f unction, an d other f unctions , and conf irm that the program operates properly. T he m odification of tool dat a ma y cause even a f ield-pro ven m achining program to change in operational status. If the user operates the machine without be ing aware of an y 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- i nclu din g blank (unmachined wor kpiece) specified in t he c ommon unit of the MAZATROL program, care is required since the tool will directly move from that position to the approac h point because of no obstructions being judged to be pr esent 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

SAFETY PRECAUTIONS

! If axis -by-axis independ ent positionin g is selecte d and simultaneous ly rapid f eed selected

for each axis, movem ents to the ending point wi ll not usually bec ome linear. Before using these functions, therefore, make sure that no obstructions are present on the path.

If the machine employs sl iding surface structure, lubr ication may prove to be insuff icient

during continuous m icrof eed mac hining ( see Note 1 belo w), an d in the worst cas e, se izure of the sliding surface could result. For these reasons, the sliding surface needs to be maintained in a wel l-lubricated con dition during s uch machining by, for exam ple, inserting an oil-film forming program (see Note 2 below).

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 re lated persons. Also, the operator must check the s ettings of the system variables before starting the above operations.

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

function, or other functions ar e execut ed, t he work piece coor dinat e system s will usua ll y be shifted. When making machine restart after manual intervention, machine locking, the mirror image f unction, or other functions , consider the resu lting 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 f unction to check the machine for norm al operation at no load . Since the

feed rate at this tim e becomes a dry run r ate 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.

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 ar ea. As a result, serious machine damage will result.

Do not design ate an incorrect puls e multiplier when performing m anual pulse handle f eed

operations. If the m ultip lier is se t to 100 t im es and the han dle op erated i nadver tent ly, axia l movement will become faster than that expected.

Introduction

This manual describes only programming based on the MAZATROL language of the MAZATROL FUSION 640M system. The description given in this manual assumes that the readers have already read the relevant Operating Manual and thoroughly understood its contents.

Programming in the MAZATROL langua ge uses an inter ac ti ve 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.

H735P0A011E

NOTE:

The MAZATROL FUSIO N 640M controls the m achining center by digital calculat ion, but it is possible that the m achining cannot be perf ormed because of the process ing of a calculation error. Before proceed ing with autom atic operat ion therefore, do not fail to ins pect the path of the tool on the display in order to verify that the machining is being done correctly.

2 SYSTEM OF COORDINATES

(

)

–Y–

–

(

)

In the preparation of the pr ogram, a system of c oordinates is used for introduci ng th e pos it ion of the machining and the form of the machining.

The system of coordinat es of the machining cen ter consists of thr ee axes of coordinat es 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

SYSTEM OF COORDINATES

X axis

Fig. 2-1 Coordinates system

2-1 Machine Coordinates System

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

Generally, the machine coordin ates 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.

SYSTEM OF COORDINATES

2-2 Workpiece Coordinates System

If the program is prepared on the bas is of the m achine 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

100

Zero point of the workpiece to be taken

M8 tapped holes

(4 places)

10-mm diameter drilled hole

100

145 150

- When the dim ensions are entered of the configuration on the basis of the ab ove 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: Workpiece zero point = ( 0, 0, 0)

P1 = (150, 0, 0) P2 = (150, 100, 0) P3 = ( 0, 100, 0)

The adoption of the work piece zero point facilitates the enter ing of the machining dimensions and therefore the programming.

SYSTEM OF COORDINATES

2-3 Machine Coordinates System and Workpiece Coordinates System

The relationship bet ween the machine coordinates s ystem and workpiece coord inates system when workpiece has been mounted on the table of a machine is shown below.

The above relationship may slightly differ according to the type of machine being used.

Note:

NM210-00513

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 coord inates is entered by utilizing the coord inates measurement function

after the workpiece is placed on the machine.

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

As the figure above s hows, positions P1 and P2 ar e entered as follows by off setting 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. Cancellation of auxiliary coordinates

The system of auxiliary coordinates is voided in the following cases: A. The system of aux iliary coordi nates specif ied in a sub- program is void ed at the t ime of the

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

B. The system of auxiliar y coordinates is voided when a new s ystem 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 retur n to the main program has the effect of voiding the s ystem of auxiliar y coordinates of the main program.)
