Chapter 7 Tool Offset & Tool Setting

Operation
(16) The tool is cut along surface B1;
(17) When X axis is not moved, the tool is retracted along Z axis and the spindle is stopped
revolving;
(18) Measure the distance " αˊ " （ assume αˊ ＝ 14.5 ） ;
(19) Press software key to enter the measuring input page, and input X
＝
14.5 on
the input page , and software key is pressed, the tool offset value or
the wearing value of X axis is set into the corresponding offset number;
(20) Other tools can also be set by repeatedly executing the steps 11
～
19.
The measuring input method is to set the differential value between the tool reference position
(such as, the tool nose position) and the tool nose position of the tool actual used during machining
as the tool offset value. For example, when the coordinate value of face B is 50.0, the actual
measured
α =49.0, so the tool offset value in X direction of this tool offset is 1.0.
Note: After the tool setting with the machine zero, G50 can’t be commanded for setting the workpiece
coordinate system.
7.4 Position Record
When the parameter PRC
（
NO.5005#2
）
is set as 1, the position record button on the machine
operation panel is valid.
The method of tool setting with position record:
1
）
The excircle or the end face of the workpiece is cut in Manual mode.
2
）
After pressing button on the operation panel on the machine side, the workpiece
coordinate values of X axis (three basic axes) and Z axis (three basic axes) are recorded into CNC.
3 ） And then, the tool is retracted, if it is in the excircle direction, the diameter should be measured.
After press , input X+ measured value in the tool compensation number corresponding
to the tool offset, and then press enter. On the end face, measure the length off the reference face,
(the reference face is assumed as Z=0), and press software key, input Z+ measured
value in the tool compensation number corresponding to the tool offset, and then press enter.
Note 1: If button is pressed for many times, CNC only records the coordinate position when
button is pressed at the last time.
Note 2: During the tool setting in the fixed position, the position record is also used: After setting the
