1. General
For machines having multiple rotation axes for freely controlling the orientation of a
tool axis, this function calculates a tool vector from the positions of these rotation
axes. The function then calculates a compensation vector in a plane (compensation
plane) perpendicular to the tool vector and performs cutter compensation for 5-axis
machining.
This function is applicable to the following machine configurations. (See Fig.1.1.)
<1> Tool rotation type machine controlled with two rotary tool axes
<2> Table rotation type machine controlled with two rotary table axes
<3> Mixed-type machine controlled with one rotary tool axis and one rotary axis
