14.16 THREE-DIMENSIONAL CUTTER COMPENSATION FOR
ROTARY TABLE
This function allows three-dimensional cutter compensation to be
performed on a 5-axis machine having a rotary table and a rotation tool
axis, such as that shown in the figure below.
The machine example shown in the figure below is a 5-axis machine
having the tool axis A about the X-axis (the orientation of the tool axis
being on the Z-axis) and the table rotation axis C about the Z-axis.
Three-dimensional cutter compensation can be performed on such a
machine.
