12.6.2 Control Point Compensation of Tool Length Compensation
Along Tool Axis
Overview
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 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.
Explanation
- Compensation of the rotation centers of two rotation axes
Compensation when the rotation centers of two rotation axes do not
match is performed.
The length from the tool mounting position to the first rotation axis
center is set as the tool holder offset value in parameter No. 19666.
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. 19661. Since parameter No. 19661 is an axis type
parameter, the compensation amount for three axes (X, Y, and Z) can
be set in this parameter.
