10.4.9 Designation Direction Tool Length Compensation
Overview
In a five-axis machine tool having three basic axes and two rotation
axes for turning the tool, tool length compensation can be applied in the
direction of the tool axis.
The tool axis direction is specified with I, J, and K; a move command
for the rotation axes is not specified directly. When I, J, and K are
specified in designation direction tool length compensation mode, the
following operation is performed automatically:
- The two rotation axes operate so that the tool axis is oriented in
the direction specified by I, J, and K. (This specifications manual
explains this operation.)
