14.17 CONTROL POINT COMPENSATION OF TOOL LENGTH
COMPENSATION ALONG TOOL AXIS
Normally, the control point of tool length compensation along the tool
axis is the point of intersection of the centers of two rotation axes. The
machine coordinates also indicate this control point.
This section explains the compensation that is performed when the
centers of the two rotation axes do not intersect and also explains how
to place the control point at a convenient position on the machine.
- Compensation of the rotation centers of two rotation axes
Compensation is performed when the rotation centers of two rotation
axes do not match.
The length from the tool mounting position to the first rotation axis
center is set as the tool holder offset value in parameter No. 7548.
The vector from the first rotation axis center to the second rotation axis
center is set as the rotation center compensation vector in parameter No.
7519. Since parameter No. 7519 is an axis type parameter, the
compensation amount for three axes (X, Y, and Z) can be set in this
