Explanation
- Operation explanation
This function calculates a vector at the tool tip position for the
three-dimensional cutter compensation function as described below.
(1) Convert the programmed coordinates from a programmed point
(pivot point) to a tool tip position (cutting point). Parameter No.
19632 is used to store the distance from the programmed point
(pivot point) to the tool tip position (cutting point).
(2) Calculate a three-dimensional cutter compensation vector at the
tool tip position (cutting point).
(3) Add the cutter compensation vector to the programmed point
(pivot point).
