4.3.4 Operations involving with manual operation

Except the automatic operations that can be performed with programs, it is possible to conduct the following manual operations with switches.

4.3.4.1 Jog feed

Jog feed enables the machine to move.

1) Set the selection mode switch to JOG position.

2) Select a motion axis so that the machine travels in the selected direction.

Note 1 2 axes may be concurrently controlled by manual operation.

Note 2 After power on, the selected axis of the machine will not immediately move even the

SELECTION MODE switch is set to JOG position. Now it is necessary to reselect an axis.

3) Selecting Jog feedrate

Note 1: The numerical values listed in the above table vary with different machines.

Note 2: The allowable deviation of the feedrates listed in the above table is approximately ±3%.

4) Rapid traverse

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

Note 1: The feedrate, time constant and acceleration/deceleration mode for manual rapid traverse are

the same as the rapid traverse under G00 program instruction.

Note 2: When the machine has a memory type travel limit selecting function, it shall be provided with an

axis with the function of returning to the reference point. When the RAPID button is pressed after power on or emergency stop, its feedrate will not change into rapid feed but maintain at Jog feedrate provided that the function of returning to the reference point is not executed.

This is because memory type travel limit dose not function before the manual return to the reference point, thereby preventing the machine from quickly reaching the end of run.

4.3.4.2 MPG feed

Make accurate adjustment for the feed of the machine with a manual impulse generator as follows.

(1) Set the SELECTION MODE switch to MPG position.

(2) Select a motion axis.

(3) Turn the handwheel of manual impulse generator.

Clockwise…………………..+ direction

Counterclockwise……… - direction

(The rotating direction depends on the settings of manufacturers)

(4) Amount of travel: Some of the operation panels are provided with the following selector

switches: ×10 means multiplying amount of travel by 10 while ×100 by 100.

Input system

×1 ×10 ×100

The amount of travel each step

Input in metric system 0.001mm 0.01mm 0.1mm

Input in inch system 0.0001inch 0.001inch 0.01inch

Note 1: If the handwheel rotates at a speed over 5 turns per second, the amount of the rotation of the

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

handwheel will differ from the travel distance of the machine. Hence do not rotate the handwheel

too quickly.

Note 2: When ×100 override is selected and the handwheel is turned at quick speed or the workbench

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

selection automatic acceleration/deceleration function is also valid for manual feed, thereby

reducing mechanical shock.

4.3.4.3 Manual absolute

If the switch is set to ON, the manual-operated travel amount will be added to the coordinate axes.

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

(2) MANUAL ABSOLUTE switch OFF: Coordinates do not change.

(Example) For example, in the following blocks:

…

G01 G90 X100.0 Y100.0 F010；①

X200.0 Y150.0 ；②

X300.0 Y200.0 ；③

…

a) The above block has been executed while block is only executed after manual ①②

operation (travel by 20.0 in X direction and 100.0 in Y direction).

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

b) Press the FEED HOLD button in the execution of the block . After manual operation ②

(Y+75.0), press the CYCLE START button so as to cancel the hold mode and continue the execution.

c) Press the FEED HOLD button in the execution of the block . Reset the machine after ②

manual operation (Y+75.0). The block restarts inputting. ②

d) When manual operation is followed by a single-axis instruction, then only the instructed axis

returns to the programmed absolute position of the axis.

N1 G01 G90 X100.0 Y100.0 F5000； N2 X200.0；

N3 Y160.0；

e) When manual operation is followed by an incremental instruction, then the position that the

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

axis moves to is identical with that is instructed while the MANUAL ABSOLUTE switch is set to OFF.

Note 1: Insert manual operations when tool radius compensation C offsets. Now the actual motion path

of the tool is as follows:

(1) MANUAL ABSOLUTE switch OFF

When tool radius compensation C is enabled：If MANUAL ABSOLUTE switch is switched off for

manual operation when tool radius compensation C is enabled, the path of the automatic tool

motion will translate in parallel by the offset of the inserted manual operation.

(2) MANUAL ABSOLUTE switch ON

When tool radius compensation C is enabled：If MANUAL ABSOLUTE switch is switched on for

manual operation when tool radius compensation C is enabled, the path of the tool under

absolute instruction after restart is as follows. The tool path for the blocks after manual operation

runs parallel to the vectors of the origin of the next block.

Tool path is determined by the vectors between the next block and the block that follow. For the angle

machining with the intervention of manual operation, its tool path is identical with the above.

If a program consists of incremental instructions rather than absolute instructions, its tool path is

identical with that when the MANUAL ABSOLUTE switch is set to OFF.

(a) Performing manual operations during execution of a block

Example 1: In the following programmed path (PA→PB→PC→PD), assuming the point PH

between PA and PB is moved to point PH′ by manual operation after pressing the FEED

HOLD button, the end point PB of the current block translates to point PB’ due to the offset

as a result of manual operation and the vectors VB1 and VB2 of the original point PB also

translate to V’B1 and V’B2.

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

The vectors between the next block (tool path from PB to PC) and the one that follows (from

PC to PD) do not need compensation. The new vectors (VC1′, VC2′) with compensation

results from the relationship between the two blocks (programmed paths from PB′ and PC to

PD and from PC to PD). Since vector VB2′ coincides with VB2, however, the section of path

between PB’ and PC as a result of tool offset is not accurately performed. But for the block

after point PC, tool offset can be precisely performed.

Example 2: If manual operation is inserted in angle machining in the case of tool radius

compensation, the feed path after manual operation will be determined by the same method

as Example 1. That is, the vectors VA2′, VB1′ and VB2′ in the figure below are determined by

translating the vectors VA2, VB1 and VB2 by an amount of manual travel and the new

vectors result from V

′ and VC2′. The block after point PC will be precisely performed by the

tool offset compensation C.

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

(b) If manual operation is inserted after the execution of single block function, the vectors VB1

and VB2 for the end points of the current block will be moved in parallel and the method for determining the following feed path will be identical with (a). MDI operation may be inserted after the execution of a block with single block function. The feed path after MDI operation coincides with tat after the insertion of a manual operation.

4.3.5 Manually returning to reference point (reference position)

The machine may return to the reference point by manual operations:

1) Set the SELECTION MODE to JOG.

2) Press the MACHINE ZERO key.

3) Move all axes toward the reference point by Jog feed.

The machine rapidly traverses to the deceleration point and then to the reference point at FL

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

speed. Rapid traverse override is still active during traversing.

4) The machine stops at the reference point and the indicator indicating the end of the return to the reference point is lit.

Note 1: The indicator is lit after the return to the reference point. If the switch for returning to the

reference point is set to ON position, the machine cannot translate in Jog mode.

Note 2: The following procedures may extinguish the indicator: (1) Move the machine away from the

reference point; (2) Press the EMERGENCY STOP button.

Note 3: For the distance to the reference point, refer to the manual supplied by the manufacturer of the

machine.

4.3.6 Operations on automatic running

The machine may automatically run by programs.

4.3.6.1 Start of automatic operation

Procedures for starting the program stored in memory:

(a) Select the program number. See Section 4.4.16 “Program number search”.

(b) Select AUTO mode.

button is pressed and at the same time the CYCLE START indicator is lit.

Note 1: The programs read in are loaded when the CYCLE START button is pressed in EDIT mode. The

loading mode is the same as that when the INPUT button is pressed for parameter setting.

Note 2: The CYCLE START button is inactive in the following conditions：

(a) When the FEED HOLD button is pressed;

(b) When the EMERGENCY STOP button is pressed;

(d) When the SELECTION MODE switch is set to a wrong position (other than AUTO or EDIT

mode);

(e) When it is search a sequence number;

(f) When an alarm is given;

(g) When automatic operation is selected;

(h) When the NC system is not ready

4.3.6.2 Suspension of automatic operation

Press the FEED HOLD button

The FEED HOLD indicator illuminates and the CYCLE START indicator goes out when the FEED HOLD button is pressed. And now,

(a) If the machine is moving, the feed slows down and stops;

(b) If the machine is in hold state, the hold state will interrupt even in FEED HOLD mode;

4.3.6.3 Single block

If the SINGLE switch is turned to ON position, the control only executes a block each time and

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

stops when the CYCLE START button is pressed.

The control only executes a block each time and stops when the SINGLE switch is turned on. When the CYCLE START button is pressed, the control stops after the execution of the next block.

Note 1: In G28, G29 or G30 mode, the tool stops at the intermediate point if the SINGLE function is used. Note 2: For fixed circular processing, the tool stops at the end point of the circular path ①, or of the ②⑥

fixed cycle (see the figure below) if the SINGLE function is active.

When the result of the fixed circular calculation is not 1, the FEED HOLD indicator illuminates except the block of the final cycle. The FEED HOLD indicator illuminates whenever block ⑥ ① or stops.②

Note 3: For the blocks of M98P—, M99 and G65, G66 or G67, the stop of the single block is invalid.

However, it is valid if the instructions in M98 or M99 block are of the addresses other than O, N, L and P.

4.3.6.4 Restart after feed hold or stop

(1) Select the AUTO mode;

(2) Press the CYCLE START button. The FEED HOLD indicator goes out when the CYCLE

START button is pressed.

4.3.6.5 The manual operations in automatic run

(1) In automatic run, suspend the operation by pressing the FEED HOLD button on the

operation panel or bring the SINGLE switch to ON position.

(2) Record the coordinates of the stop position displayed by the location display unit.

(3) Perform JOG operation (see Section 4.3.4.3).

(4) Return the tool to the recorded coordinates (the origin of JOG operation).

(5) Set the SELECTION MODE switch to the position before JOG operation so as to restart

automatic run.

(6) Press the CYCLE START button.

4.3.6.6 The MDI operations in automatic run

(1) Set the SINGLE switch to ON position.

(2) Select MDI operation mode.

(3) Perform MDI operation.

(4) To restart automatic operation, return to the original operation mode and press the CYCLE

START button on the operation panel.

Note 1: The modal data reserved in cycle movement is under influence when MDI instruction is used.

Note 2: The modal data instructed by MDI is still valid for automatic MDI operation.

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

Note 3: Too radius compensation C is not performed during MDI operation.

Note 4: MDI operation is disabled in feed hold state.

4.3.6.7 Skipping over optional blocks

When some block contains “/n”(n=1 to 9), the function allows the control to skip over the block. Switches correspond to the 19 numbers respectively.

Note: While blocks are being read in the buffer from storage, the validity of function of skipping over optional blocks is judged. Therefore the function is invalid for the blocks read in buffer register.

4.3.6.8 Feedrate override

For the feedrate set by F function, it is possible to set an override in the range of 10% to 200%. An override of 10% increment is recommended.

4.3.6.9 Dry run

If the switch is set to ON position in the cycle operation instructed by storage or MDI, the F function does not work and the machine travels at the following speeds.

RAPID button ON/OFF In rapid traverse In cutting feed RAPID button ON Rapid traverse Maximum Jog feedrate RAPID button OFF Jog feedrate (see Note) Jog feedrate

Note: The dry run of rapid traverse may be disabled or enabled by parameter setting.

4.3.6.10 Machine lock

When the MACHINE LOCK switch is set to ON, the movement instruction pulse is inhibited. Therefore the position indication for circular feed start or JOG operation is continuously updated according to input instructions. But the machine does not move itself. The function is used to check procedures.

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

Hence the indicator for returning to the reference point is not lit.

Note 2: M, S, T and B functions are performed.

4.3.6.11 Display lock

When the DISPLAY LOCK switch is activated, the coordinates indicated by the location display unit are locked. For instance, when the coordinate system is moved as a result of JOG operation, the use of this switch prevents the indicated values from changing by manual movement.

Note: The function is optional.

4.3.6.12 Mirror image

Once the mirror image switches of axes X and Y as well as the 4th axis are activated in automatic operation, the axes move reversely. The reference point is returned to by JOG or automatic operation, the movement between the intermediate point and the reference point does not inverse and position display depends on the actual movement of the tool. This may be achieved by setting parameters with MDI unit (see Section 4.4.7).

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

4.3.6.13 Rapid traverse override

It is possible to set the rapid traverse override switch of optional overrides 100%, 50%, 20% and F0 on the operation panel of the machine.

When the feed speed is 10m/min and the switch is set to 50% position, the actual feed speed will be 5m/min.

F0 is a fixed speed (feedrate) provided by the manufacturer of the machine. The function applies to the following conditions:

(1) The rapid traverse specified by G00;

(2) The rapid traverse in fixed cycles;

4.3.6.14 External workpiece number search function

Select a workpiece number to be processed with the switch on the operation panel of the machine (No example of the operation panel is given in this user manual). (Machining programs are pre-stored in the part program storage.) Press the START button. Now the system automatically executes the program corresponding to the workpiece number. By using the function, operator does not need to search the stored program numbers so as to reduce dry run time and errors.

(1) Preparation for the program: In the situations using the function, the numbers assigned to

programs shall correspond to the workpieces to be processed. That is, a number among 01 to 31 shall be designated for each workpiece to be processed. The relevant program number is expressed as follows:

0(:) 0 0

They are stored in the part program memory. As shown in the following examples, each program shall be started by the address 0 followed by a program number and ended by M02, M30 or M99.

In addition, the storage of the programs irrespective of workpiece number is allowable.

0 0001； N 0001 G00…； The program corresponding to workpiece No. 01

……………………

N 120 M02； 0 0002； N 0001 G00…； The program corresponding to workpiece No. 02 ……………………

…………………… N 300 M30； 0 0004； N 001 G00……… ………………………

………………………

□ □ (0 for EIA and : for ISO)

Workpiece number (01 to 31) Optional workpiece number

The program corresponding to workpiece No. 04

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

N 080 M02；

0 6247； N 001 G00……… ……………………… Programs irrespective of workpiece number ……………………… N 034 M99；

Note 1: Each program shall be started by the address 0 followed by a program number and ended by

M02, M30 or M99. However, M02, M30 and M99 cannot be specified in the middle of the program. If one of them is specified in the middle section, the program that follows will regarded as another program segment (the block following M02, M30 or M99 is immediately numbered as a program when the program is stored in memory).

Note 2: The allowable quantity of workpiece numbers depends on factory setting (see the manual of

the machine).

Note 3: For the machine system provided with external workpiece number search function A, the

allowable maximum workpiece number is 31. Now the first two digits of the program number corresponding to a workpiece number must be 00.

(1) Operating procedures

Operating procedures vary with different manufacturers of machine. The operating procedures described below are general. Refer to the manual supplied by manufacturer of the machine for specific operating procedures.

Note 1: Select the automatic mode and then set the program (01 to 31) corresponding to the workpiece

number with the rotary switch on the operation panel on the machine side. When the START button is pressed, the program corresponding to the set workpiece number will be searched out and machining performed with the start of the program.

Note 2: When a workpiece number is set to 00, the corresponding program will not be searched if the

START button is pressed. The execution starts from executable section of the current program. For the situations that starts in the midway of the program or that the executing program is independent of workpiece number, it is necessary to set the workpiece number to 00 and press the START button after sequence number search or program number search.

Note 3: The function does not apply to MDI operation but automatic operation.

Note 4: If a program number corresponding to the workpiece number is not stored in the memory, an

alarm (No. 59) will be given once the START button is pressed.

Note 5: It is not always necessary to select the relevant program even a workpiece number is selected

with the dial. Refer to the manual supplied with the machine for the procedures for selecting a program. When workpiece number search function A is selected, program search is performed after the NC system starts automatic operation in reset mode.

4.3.7 JOG feed at any angle

Set an angle and feedrate in the plane of X and Y and then press the START button. In this way the machine may feed at any set angle by JOG operation.

(1) Set the SELECTION MODE switch to the mode of JOG feed at any angle

(2) Set an angle with the angle setting dial. The position of an angle is selected among 0-71 with a

2-digit BCD code. 0 ~71 correspond to 0 ~360° respectively (in 5° increment).

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

For angle setting, make sure to switch on angle strobe pulse. If angle strobe pulse is switched on, the formerly set angle will remain valid.

As shown in the above figure, the + direction of Axis X is 0° and that of Axis Y is 90°.

(3) Select a feedrate (speed in tangential direction) with the Jog feed dial.

(4) Press the START button in the mode of JOG feed at any angle. Then the machine moves at

the selected feedrate in the set direction.

If the JOG RAPID button is pressed, the machine will feed at the maximum Jog feedrate. The machine feeds when the JOG RAPID TRAVERSE button is switched off and stops feed when it is switched off.

Note 1: If axes X and Y are interlocked, both axes will slow down and stop. They will restart once the

interlocking is disabled.

Note 2: In automatic operation, it is possible to insert JOG feed at any angle when the machine is stop

in feed hold mode.

Note 3: For the situation with external deceleration selection, JOG feed at any angle is also active.

Now the tangential feed is equal to the external decelerating rate.

Note 4: The automatic acceleration and deceleration for cutting feed also apply to the JOG feed at any

angle.

Note 5: JOG feedrate at any angle does not change with Jog feedrate even during the switching

between metric and inch systems.

4.3.8 Manual insertion

For the specific axis (fixed by parameter) in automatic operation, the movements operated with handwheel may be performed in addition to the self-motion of the axis.

4.3.8.1 Inserting operations by MPG(manual pulse generator/handwheel)

Manual insertion is possible by turning the manual pulse generator in the following conditions.

(1) Mode: automatic mode or MDI mode

(2) Operating state: Manual insertion is possible during linear interpolation, arc interpolation, spiral

interpolation or sine-curve interpolation.

However, the following conditions are excluded:

(I) When an alarm is given;

(II) When any axis does not move;

(III) When positioning is valid;

(IV) When interlocking is active;

(V) In the absence of travel instruction.

GSK983M Milling CNC System Operation Manual (Volume II: Operations)

(3) Manual axis selection signal

Manual axis selection signals (HX, HY, HZ, H4 and H5) are switched on (contacts close) for the axes to perform manual insertion.

4.3.8.2 Manual inserting movement by MPG

(1) Amount of travel: The amount of travel to be inserted by manual shall be identical with that

during JOG feed. The amount of travel depends on the scale of the manual pulse generator and JOG feed overrides (X1, X10 and X100) and is added to that of automatic operation.

(2) Traverse speed: The axial speed for JOG insertion is the result of the addition of the travel speed

of automatic operation to that inserted by manual. Therefore, axial speed is limited to rapid traverse speed (Parameter HR) in the event that axial speed exceeds rapid traverse speed. Displacement mismatches the indicated value of the manual pulse generator.

(3) The correspondence between manual-inserted travel and all signals is as follows:

Signal Travel

Machine is locked Display is locked. Mirror image of Axis X

(4) The correspondence between manual-inserted travel and position indications is as follows:

Affected: The tool does not move when MACHINE LOCK is enabled.

Affected: Relative coordinates remain unchanged when display is locked.

Not affected: The machine moves forward when the handwheel is turned clockwise.

Indication Travel

Absolute coordinates Relative coordinates Mechanical coordinates

Not affected: Manual-inserted pulse is not added to absolute coordinates

Affected: Manual-inserted pulse is added to relative coordinates
