(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

GSK983T Turning CNC System User Manual

Fig.4-8

Amount of move: X 1 means move is multiplied by 1; while ×10 is by 10; while ×100 is by

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.

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.

4.3.6.7 Skipping over optional blocks

Fig.4-23 Skip block

This function is used to make the control to skip over the block headed with “/”.

Fig.4-24

When the “/” is defined to be followed by a numeral, and the BLOCK SKIP SWITCH on the operator panel of machine is set to “ON”, in the memorizer working, the information is ignored which is contained in the block /n corresponding to the specified BLOCK SKIP number n.

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 )

4.3.6.10 Machine Lock

Fig.4-27 Machine lock

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.

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

if hand disk is rotated in positive direction
