15. COMPENSATION FUNCTION
G92 Z760.0 X1100.0 ; Sets a workpiece coordinate system with
respect to the programmed absolute zero point.
G00 G90 X850.0 ; Moves the tool to X850.0.
That is the tool is moved to a position that is a
specified distance from the measurement
position along the Z–axis.
H01 ; Specifies offset number 1.
G37 Z200.0 ; Moves the tool to the measurement position.
G00 Z204.0 ; Retracts the tool a small distance along the
For example, if the tool reaches the measurement position with Z198.0;,
the compensation value must be corrected. Because the correct
measurement position is at a distance of 200 mm, the compensation value
is lessened by 2.0 mm (198.0 – 200.0 = –2.0).
