Volume Ⅱ Chapter 4 Operation

(3) Select the moving axis

Press the direction key corresponding to this axis, the tool moves in the selected direction.

Fig.4-6 Select the moving axis

Note1: Two axes can be controlled simultaneously by Manual operation. Note2: After power on, if the tool don’t move by the selected axis even the Mode selection is preset to

“MANUAL” position with an axis selected. Now it is necessary to reselect an axis.

(4) Rapid traverse

An axis rapidly traverses in the selected direction when this key is pressed.

Fig.4-7 Rapid traverse

Note 1: The time constant and acceleration/deceleration mode for JOG rapid traverse are the same as

that of by G00 code ( it is set by machine tool manufacturer ).

Note 2: The federate of JOG rapid traverse can be set as 0.25 times ,0.5 times or 1 time of the speed

specified by G00. F0 is set by system parameter NO.113 ( it is set by machine tool manufacturer ).

Note 3: When the machine has a storage type travel limit selecting function (parameter No.9.0 ISOT ), for

an axis with the function of reference point return, if the [RAPID] key is pressed after power on or emergency stop, the feedrate will not change into rapid rate but maintain at a Jog feedrate

provided that the reference point return is not performed. This is because storage type travel limit does not take effect before the manual reference point return, thereby preventing the machine from quickly reaching the end of travel.

4.3.4.2 MPG

Accurate adjustment for the rate of the machine feed and move can be done with a manual pulse

generator(MPG).

(1) Select the MPG mode; (2) Select a move amount

Page 10

GSK983T Turning CNC System User Manual

(3) Select a move axis: press X or Z axis move key (either + or - direction) (4) Turn the handwheel of the manual pulse generator.

Clockwise……………….+ direction

Counter clockwise………- direction

(The rotating direction depends on the settings of the machine builders)

Note 1; If the MPG rotates at a speed over 5 turns per second, the amount of the rotation of the MPG will

differ from the move distance of the machine. Hence do not rotate the MPG too quickly. Note 2: Incremental feed function is not required if MPG is fixed on the machine. Note 3: When ×100 override is selected and the MPG is turned at quick speed to make the tools or work table

move at “rapid traverse” rate, the machine will be subject to impact if it is stopped abruptly. The

selection automatic acceleration/deceleration function is also active for JOG feed, thereby it may

reduce mechanical shock. Note 4: See section 4.3.7 for the MPG insertion function.

4.3.4.3 MANUAL ABSOLUTE ON/OFF

MANUAL ABSOLUTE ON/OFF is used to define whether the move amount because of JOG operation is added to the automatic axis coordinate. When it is ON, the move amount is added to the coordinate system, or else, not.

(1) MANUAL ABSOLUTE switch ON : Coordinates vary with the manual operation.

Page 11

Volume Ⅱ Chapter 4 Operation

(E) Manual operation during tool nose radius compensation When the next block is an incremental command, then the action is identical with that is

commanded while the MANUAL ABSOLUTE switch is set to ON or OFF.

(F) Manual operation during tool nose radius compensation If MANUAL ABSOLUTE switch is switched OFF:

If manual operation is executed when MANUAL ABSOLUTE switch is switched off during tool radius compensation, the tool will move along the tool path wihich parallel to that without manual operation in the restarting auto mode. The parallel space equals to the move amount in manual operation.

If MANUAL ABSOLUTE switch is switched ON:

If MANUAL ABSOLUTE switch is set for ON for manual operation in the tool nose radius compensation mode, the automatic running path of the tool by absolute command after restart is as follows. The vectors set in the rest of the block and the origin of the next block will be offset parallelly.

Tool path is determined by the vector between the next block and the block that follows as well as the move amount generated by manual operation. This is also applicable for the case by manual operation during corner.

Fig.4-15

When the BLOCK SKIP SWITCH on the operator panel of machine is set to “OFF”, the information of the block specified by /n is active. That means the operater can determine whether to skip over the block containing /n.

The 1 in the character /1 can be ignored. However, if two or more BLOCK SKIP SWITCH are used for one block,it can not be ignored.

Example:

( incorrect ) ( correct )

//3G100×10.0； /1/3G00×10.0；

The function is ignored when the program is inputed into the memory, and the block containing

/n is stored into it regardless of the setting of BLOCK SKIP SWITCH.

Page 20

GSK983T Turning CNC System User Manual

The block stored in the memory can be outputed regardless of the setting of BLOCK SKIP

SWITCH. The BLOCK SKIP is active even in the operation of sequence search.

The number of BLOCK SKIP SWITCH on the operator panenl is different for different machines,

for the details, please see the machine user manual. The BLOCK SKIP on the operator panle is

generally set to be BLOCK SKIP 1.

Volume Ⅱ Chapter 4 Operation

When the MACHINE LOCK switch on the frame is set to be “ON” or that on operator panel is active, the move command pluse will be repressed. Therefor, the position display of feed cycle start or manual operation will be refreshed by the command inputed, however, the carriage doesn’t move in the program execution, and the machine coordinates don’t change either. This function is used to check program.

Note 1: When G27, G28 or G30 command is set, the machine will not return to the reference point. Hence the

indicator light for reference return is not lit up.

Note 2; M, S, T functions are performed.

4.3.6.11 Auxiliary Lock

Fig.4-27 Auxiliary Lock

When the AUXILIARY LOCK is ON, the machine carriage moves normally, but the M,S,T function is not performed, this function is used to check program.

4.3.6.12 Rapid Override

Fig.4-28 Rapid Override

The rapid overrides F0, 50%, 100% are available on the operation panel of the machine. If the rapid rate is 10m/min, and the override is 50%, then the rate becomes to be 5m/min. F0 is a fixed speed (feedrate) specified by the machine builder.

This override applies to the following conditions:

(1) Determine the rapid rate of G00;

(2) Determine the rapid rate in canned cycles;

(3) Determine the rapid rate in G27, G28, G29 and G30 modes;

(4) Determine Jog rapid rate;

(5) Determine the rapid rate in manual reference point return.

4.3.7 MPG Interruption

GSK983T Turning CNC System User Manual

Fig. 4-29

4.3.7.1 Summary

For the specific axis (set by parameter No.314.0 和 No.314.1) in auto running, it may be moved

manually by handwheel (MPG) to overlap the path in the auto running.

4.3.7.2 MPG (manual pulse generator) interruption

Manual interruption can be performed by turning the manual pulse generator in the following

conditions.

（1） Auto mode or MDI mode. （2） Operating state: Manual insertion is possible during auto running and linear interpolation, arc

interpolation.

However, the following conditions are excluded:

（Ⅰ）When an alarm is being given; （Ⅱ）When machine lock is active; （Ⅲ）When positioning is valid; （Ⅳ）When interlocking is valid; （Ⅴ）No move command.

（3） Manual axis selection signal

Manual axis selection signals (HX , HZ) are powered up (contacts making) for the axis to perform

manual insertion.

4.3.7.3 Movement of manual insertion

（1）Amount of move

The amount of move by manual insertion is identical with that of the MPG feed. The amount of move depends on the scale of the manual pulse generator and manual feed overrides (X1, X10 and X100) and is added to that of automatic running.

Page 23

Volume Ⅱ Chapter 4 Operation

（2）Move speed:

The axial speed for manual insertion is the result of the addition of the move speed of auto

running to that by manual insertion. Therefore, axial speed will be limited to rapid traverse rate (parameter #92（RPDFX）and #93（RPDFX）) in the event that axial speed exceeds rapid traverse rate.

Because the distance whose speed exceeds the rapid traverse rate is lost, the scale value displayed on the MPG is invalid. （3）The relations of manual insertion to various signals are as the following table:

Table 4-6

（4）The relations of manual insertion to various signals are as following table:

It is affected, that is, the tool does not move if the

machine is set to ON

It is affected, that is, the relative coordinate does

not change if the display is locked

It is not affected, that is, machine moves positively

Also in above figure, if the start point locates at the tool nose tip, and it needs to be set at a point of X=120.0(diameter),Z=70.0, while it actually locates at X=121.0 (diameter), Z=69.0, key in the offset value of the workpiece coordinate system:

X=1.0 Z=－1.0

The desired coordinate system may be obtained.

The actual offset may be simply set by the direct offset input method for workpiece coordinate system in section 5.12.5.

Page 45

Volume Ⅱ Chapter 4 Operation

Note 1: The offset of the workpiece coordinate system takes effect immediately after the offset value is set. Note 2: After the offset value is set , then set coordinate system by G50, the offset doesn’t take effect. e.g. Whatever the offset is, the current tool start point X=100.0 Z=80.0 is set for the new

coordinate system if the point G50 X=100.0 Z=80.0 is set.

Note 3: When performing the manual reference return after the offset value is set, once the automatic

coordinate system is set, the offset takes effect immediately, and the set coordinate system will be offset right away.

Note 4: The offset in X axis by diameter or by radius is specified by the diameter or radius value in part

program.

4.4.12.5 Direct measured value input of workpiece coordinate system offsetting

If there are deviation between the coordinate system used in programming and the coordinate system actually commanded by G50 and automatic coordinate system, offset the coordinate system by direct measured values as follows:

4.4.18 Sequence number search (functional key PROGRAM )

Sequence number search is usually used to search a sequence number in a program and start

or restart the program from the block whose sequence number is searched. Its skipping over blocks exert no influence on the NC system. Namely when skipping over blocks, the coordinates of the blocks skipped over, M, S, T or G codes do not change the coordinates and modal values of the NC. When a user macro program is supplied, sequence number will not be displayed in searching.

Therefore, necessary M, S, T, G codes and coordinate system should be set for the blocks to be

started or restarted according to sequence number search. This block searched is usually a breaking point in a process. If it needs to restart from the block searched in program, the present state of the machine and NC system must be checked by specifying M, S, T, G codes and coordinate system etc. with MDI.

GO is correct and if the tool contacts workpiece when the tool moves to the machining restarting

position. Press the CYCLE START key after manually moves the tool to a position that the

following tool move does not contact the workpiece. Now the tool moves to the restarting position by dry run in the sequence of the Z, X axis, and restart machining.

(2) Restart machining (Q type) after the occurrence of the following conditions:

(a) Switch off the power. (b) Press the EMERGENCY STOP button. (c) The machine immediately stops due to storage type travel limit alarm. (d) The coordinate system changes after the last automatic operation.

Example:

(Ⅰ) Specify G50 command through MDI. (Ⅱ) Move the coordinate system. (Ⅲ) Set the automatic coordinate system after reference point returning. (Ⅳ) Reset the coordinates.

(a) After power on or the releases of emergency stop and travel limit alarm, the machine

performs the reference point return prior to the restart (see the notes below).

(b) The tool is manually moved to the programmed start point of machining and set modal data

and coordinate system which are identical with that of the the machine restart.

(d) Set the PROG RESTART key on the operation panel of the machine to ON.

(e) Display the program by pressing the PROGRAM key. Search the required program when

it is not available.

(f) Return to the the program start point. (Press the cursor ∧ key in Auto mode). (g) Keying in the Q key and the sequence number, cursor ∨ key , the page switch to the

program restart automatically.

Search the sequence number that the block restarts.

When the same sequence number appears for many times during searching, the higher four digits are specified as the times of sequence number appearances and the lower four digits as its sequence number.

(h) Perform the same operations as (f),(g), (h) steps of P type. (i) When the tool moves to the machining restarting position, check that the tool does not contact

workpiece. If necessary, manually move the tool to a position that does not contact the workpiece.

(j) Check if the distance indicated by the DISTANCE TO Go is adequate.

(k) Return to the Auto mode and press the CYCLE START key. Now the tool moves to the

restarting position by dry run in the sequence of the Z, X axis, and restart machining.

Note 1: In the following conditions, pressing the P key, the sequence number and the cursor ∨ key, it

does not restart the program.

(Ⅰ) After power on, no automatic operation is performed.

(Ⅱ) Automatic operation is not performed after the release of emergency stop or storage travel limit

alarm.

(Ⅲ) The automatic operation is not performed after the coordinate system is established, changed or

moved.

The (Ⅰ), (Ⅱ) above or 94, 96, 97 alarm reset causes P/S 97 alarm.

P/S 94 alarm is issued by the establishment of a coordinate system.

P/S 96 alarm is issued by the move of a coordinate system.

The block for the restartable machining is one of the many blocks. The block follows the block when

the coordinate system is last set or changed before the interruption of machining. Note 2: In P or Q type, the tool moves to the machining restarting position by one axis each time. The stop of

Page 55

Volume Ⅱ Chapter 4 Operation

a single block is possible after the motion of the 1 operation can be inserted. The returned axes cannot move.

Note 3: When input signals, offsets and other conditions are different from the past in searching, the tool

cannot return to the machining starting position. i.e. the single block switch is set to ON or switch to Auto/TAPE mode for continuous search operation.

Note 4: When feed hold is active during search or reset operation is performed in or after search, make sure

to carry out program restarting operation from the beginning. After the search, however, the reset

state in MDI mode is defined by parameter 006 CLER. Note 5: Cycle start can be ignored provided that the program restart switch is set to ON. Note 6: Always set the manual absolute switch to ON position for manual operation no matter it is before or

after machining.

When a program restarting operation instead of resetting is performed after manual operation or

when manual operation is performed along the axis that has not returned to the machining restarting

position, the motion concerned is assumed to be performed as the manual absolute switch is set to

ON position regardless the manual absolute switch is at ON or OFF position. Note 7: In principle, the tool cannot return to the correct position in the following cases:

(a) When the manual absolute switch is set to OFF for manual operation.

(b) When the tool is moved in the lock state of the machine.

(d) When the coordinate system is not set at the beginning of incremental programming.

(e) When program mirror image function is used.

(f) When manual operation is inserted during the returning of an axis.

(g) When machine lock is disabled after the program restart is commanded in machine lock state.

(h) When program restart command is given during the execution of the cutting blocks with skip or

before the block with absolute command being executed.

(i) When the program restart is commanded in the blocks of the compound canned cycle.

(j) When coordinate system and offset are established after search. Nevertheless, in the condition of

switching. In this case, interruption in the mirror image remains the same. In addition the P type

return of the tool in the condition of (e) is also available.

Note 8: When the specified block only includes M98, M99, macro program calling command (M65, G66 and

G77) or macro program statement, or block not specified is searched, No.60 alarm will be given. Note 9: When program restarting operation is commanded and G28 is detected without returning to the

reference point after power on, release of emergency stop or travel limit alarm (immediate stop), P/S

alarm (98) will be issued. Note 10: After the search, P/S alarm (99) is given when a move command is executed through MDI

operations before axis motion. Note 11: After the program restart is commanded, “RSTR” blinks at the bottom of the LCD screen before the

return of the last axis (Z).

Note that no alarm is given in above case!

A word comprises an address and the numeral that follows. For user macro program, however, the concept of word is indefinite. Hence the concept of “edit unit” is adopted. Edit unit serves as the object of alteration and deletion in a single operation. Move the cursor to the edit unit beginning in a single pass. For data insertion, the data is inserted behind the edit unit. Definition of edit unit (1)From one address to the next one; (2)Address:character, IF, WHILE, GOTO, END, DO, =, ; (EOB) According to the definition, a word is also an edit unit. On the basis of the following explanations about edit, strictly speaking, word shall be called “edit

unit”.

Note 2: During program execution, machining is temporarily suspended by single block stop, feed hold and

other functions. Nevertheless, continuing to execute a program is not allowed after program alteration, insertion and deletion; otherwise the program cannot be correctly executed. Program is displayed on the LCD after subsequent machining.To alter stored data in Edit mode, they must be altered in reset condition before program execution or when resetting operation is performed after editing.

Note 2: If the power supply is switched off after the stop of automatic operation, a time error up to 6

minutes may be caused after power on again.

Note 3: When necessary, time can be preset through setting operations. See section 4.4.8, the data

number is 57, 58, 59.

4.4.24 Menu switch function

It is possible to enable or disable the switch function of the CNC memory using the LCD instead of the machine operation panel. With this function, the number of switches on the operation panel can be reduced.

The signals that may be switched on or off through the LCD are as follows:

（1） SINGLE BLOCK

（2） MACHINE LOCK

（3） DRY RUN

（4） BLOCK SKIP1～9

（5） X MIRROR IMAGE，Z MIRROR IMAGE

（6） DISPLAY LOCK

（7） AUX FUNC LOCK

（8） MANUAL ABSOLUTE

Once the switch signal data set on the LCD is stored into magnetic memory, these switch data remains unchanged even the power is cut off.

These signals are not completely determined by those displayed on the LCD.

These signals are deemed to be switched on no matter whether the machine panel signals or the signals set on the LCD are switched on.

Therefore, these signals can be switched on or off through the LCD if they are cancelled through the operation panel or disconnected with the signal cables.

Refer to machine manual for signals on/off by MDI/LCD switch.

Fig. 4-77

The maximum graphic range shown in above figure covers 144mm horizontally, 108mm vertically. If the drawing scope is over this range, the scale that ranges from 0.01 to 100.00 may be used. Usually the scale is defined by following factors:

SCALE=smaller one of H, or V

SCALE H =

SCALE V =

length path programmed horizontal

length path programmed upright

: 144mm (by radius )

288mm (by diameter)

β: 108mm (by radius )

When the tool path is out of the center, the tool path may exceed the drawing range. Then it may

use the following 4 parameters: RANGE X (MAX): RANGE X (MIN): RANGE Z (MAX): RANGE Z (MIN):

So the graphic center (GCX,GCZ) may be calculated by following formula:

GCX=[X(MAX)+X(MIN)]/2 GCZ=[Z(MAX)+Z(MIN)]/2

Note 2: Even X axis is specified by diameter in programming, X (MAX),or X (MIN) is specified by radius.

Volume Ⅱ Chapter 4 Operation

The values are determined by input unit 0.001mm or 0.0001 inch. In addition, it turns into

0.0001mm, 0.00001inch if “insertion unit 1/10” is selected.

Once these parameters are set, they remain active till T key is pressed in Graphic page.

Even the workpiece coordinate origin is changed, the graphic origin and center is not changed on

screen. That is, workpiece coordinate origin always coincides with the graphic origin.

4.5 Display on Position Displayer (Optional)

The position displayer shows the current position. There is an axes position reset key on position displayer, when this key is pressed, the

corresponding axis position is cleared and this point will be taken as the origin.

When a coordinate system (G50) is set by parameter (PPD), or by program, or by MDI panel, its

coordinates can be set into the position displayer.

Note 1: If the displayer lock switch is set to ON, the move in this state is equivalent to no moving in

position displayer. So there is a difference between the actual moving amount and the value displayed.

Note 2: Position is displayed by inch unit when inputing by inch; and millimeter unit when inputting by

millimeter. Press RESET key to clear the displayer when switching between millimeter and inch

units. Either of the switching between millimeter and inch units does not change the data displayed, but change the decimal point position.

Note 3: The displayer doesn’t show the mechanical compensation such as backlash compensation.

In automatic acceleration and deceleration, thread cutting, it may result in the incorrect δ1,δ2

lead as Fig.4.1, so δ1,δ2 allowance should be given in programming.

δ2=T1·V (mm)……………………………………………(A-1) Unit: T1: s, V: mm/s V is defined by thread lead L and spindle speed R.

·R(r/min)·L(mm)

O The servo time constant T1(s)is usually calculated by T1=0.033.

If a is confirmed, the time t for precision is decided by formula (3), put t value into (2) to

get δ1. And the V,T1,T2 are decided by the same method as that of δ2.

Because δ1 is hard to get by calculation, it may be got by the following figure, see the

explanation.

First get the thread precision a at (1) according to the thread grade and lead, then get δ1 for V=100mm/s at (2) by the acceleration and deceleration time constants in machining. Thus δ1 at other velocity can be got according to the thread cutting feedrate at (3).

D4.3 Radial error for arc cutting

There is an error between the output shaft and input shaft due to the motor lag when using DC servo motor. In linear interpolation, no error occur in the commanded linear path by the tool, but in circular interpolation, especially in high speed arc cutting, there is a radial error. This error may be obtained by the following procedures:

Programmed path

Actual path

Select the Manual mode, connects ZRN signal (to +0N), the machine moving parts will traverse by feeding to reference point by Manual key. It decelerates and moves at a certain low speed after touching the deceleration limit switch(sending *DCX.*DCZ signals for

reference point return), then the feeding stops at the 1

grid of the limit switch resetting and the reference return finish signals ZPX,ZPZ are sent. The direction for returning to reference point may be set dependently for each axis. Once the reference return is finished and ZPX,ZPZ signals are sent out, JOG feed command fails before ZRN signal is cut off.

(2) Reference return by magnet switch

The so-called reference return by magnet switch means that in actions of (1), feeding stops after the front edge of ZDX,ZDZ signal substituting the grid signal is given, and it sends out reference return finish signal ZPX,ZPZ. In addition the reference return detection can’t be done by G27.
