GSK928TEⅡ Turning CNC System User Manual

Ⅲ. Safety Suggestions for Programming

1）Setting a coordinate system

Incorrect coordinate system may cause the machine not to work as expected even if the

program is correct, which may injure the operator, and damage the machine as well as its

tool and workpiece.

2) Rapid traverse (positioning)

When G00 rapid traverse performs the positioning( nonlinear motion to position between

its starting point and end point), make sure that the path for the tool is safe before

programming. The positioning is to perform the rapid traverse, and when the tool and the

workpiece are interfered, the tool, the machine and the workpiece may be damaged, and

even the operator injured.

3) Applicability of user manual

The manual introduces in detail all functions of the system, including optional functions

and max. controllable ranges, which are subject to change with the machine. If there is

any doubt, please read the instruction for the machine。

4) Functions of CNC system and machine

CNC machines depend on CNC systems, but also power voltage cabinets, servo systems,

CNC and the operator panels. It is hard to explain all the integrated functions,

programming and operation. Do not use integrated instructions not included in the manual

until they have been tested successfully.

Safety Warning

Ⅳ. Notes and Safety Suggestions for Operating Machine

1）Test the machine without workpieces or tools. Make sure that the machine runs well before

it starts to work.

2）Check the input data of the system carefully before operating the machine. Incorrect input

data may cause the machine to work improperly, so as to damage the workpiece and the

tool, as well injure the operator.

3）Make sure that the input feedrate of the system is suitable for the expected operation.

Feedrate has a maximum for each machine, and the amount of the feed rate is subject to

change with operation. Choose the maximum according to the instructions of the machine.

Improper feedrate leads the machine to work wrongly, so as to damage the workpiece and

the tool, as well injure the operator.

4 ） When tool compensation is needed, check the direction and the amount of the

compensation. Improper compensation causes the machine to work wrongly, so as to

damage the workpiece and the tool, as well injure the operator.

5）If the machine is to run in Manual mode, check the current position of the tool and the

workpiece, and correctly specify the moving axis, moving direction and the feedrate.

MPG(Handwheel) control with great override, such as 100, may damage the machine and

its tool, even injure the operator.

6）If the tool is return to the reference point, make sure that the machine has been equipped

with the device to detect the reference point, otherwise, the tool can not reach the

reference point, which may damage the machine and its tool, and even injure the operator.

4.3.3 Inputting/Editing Content of Part Program

CNC machining is defined that the system automatically completes the machining of workpiece

according to the part program sequence input by user. Each program is composed of many

blocks and each block consists of a block number, codes and data. Start the machine and gain

the standard workpiece after inputting the part program content according to the technology flow.

EDIT mode of CNC system uses the full-screen and part programs are employed with the file management mode.

4.3.3.1 Automatically Creating a Block Number

Each part program contains many blocks and each block begins with the block number“ N**** ”;

After a new program is created, the system will automatically generate the first block

number“ N0000 ”; After one block is input and

is pressed, the system will generate the

next block number. In the course of input, the increment of block number is defined by P23. When a block is inserted, the system will automatically consider the 1/4 integer value of P23 as the increment to generate the block number. When M98, M97, M91, M92, M93, M94 and others codes related with the block number are executed, there are no repetitive block numbers in the program, otherwise the system will alarm. If the above codes are not executed, the block number can be repeated.

See Fig. 8 for a program generation and inserting a block number in a block (P23 value is 10).

4.3.3.2 Inputting Content of Program

EDIT mode of the CNC system is employed with the full screen. Inputting content of program is

executed in EDIT mode.

(1) Create a new program according to the creating method of new part program.

(2) After the block number N0000 is displayed, input the content of one block by keyboard.

(3) Input completely one block and then press . (4) The system will generate the sequence number of next block and the content of program

should be input continuously.

(5) Input completely the last block and press

to end the input of content of program.

(6) The cursor rapidly moves in the block.

Press

once, and the cursor will point to the head of word; press it again，and the

cursor points to the head of block, and the above steps are executed circularly.

Press

once, the cursor points to the end of block.

(7) Insert a block in the first block.

Move the cursor to the head of the first block and then press .

Note: There are 255 characters at most in one block. When the characters exceed the screen,

pressing

displays one character left.

4.3.3.3 Inserting a Block

Insert one or more blocks between two blocks.

GSK928TEⅡ Turning CNC System User Manual

(1) Press to move the cursor to the first one of two blocks.

(2) Press

to move the cursor to the behind of last character, or press to move

directly the cursor to the behind of last character.

(3) Press , and the system will generate a new block number between two blocks (the

increment of sequence number is 1/4 integral value of P23, and if there is not enough, the block number of the next block is rewritten.) and blank one block.

(4) Input the content of required block.

(5) After the content is input,

is pressed to insert blocks. When only one block is inserted,

the operation is not executed.

(6) The inserting is completed.

(7) If the block is inserted before the first block,

is pressed to move the cursor to the

under “N” of the first block, and the system will generate a new block number before the first

block after is pressed.

Note

：

After one block is inserted behind the last block and is pressed, the system will

automatically generate the next block number.

Example：Insert a new block M3 between N0020 and N0030 in Fig. 8 as follows:

(1) Press to move the cursor to N0020 , and press to move the

cursor to the behind of Z0.0.

(2) Press

， and the system will automatically generate one block number and blank a

block to display N0022 as Fig. 9. The cursor points to the first input character of the new

block.
