Departure function DEP PLCT
Application
With the NC function DEP PLCT, the control departs from the contour on a circular path, followed by a tangential straight line to the last contour element.
The coordinates of the end point PN are programmed with polar coordinates.

Requirement
- Pole CC
You must define a pole CC before programming with polar coordinates.
Description of function
This NC function encompasses the following steps:
- On a circular path from the last contour point PE to the auxiliary point PH
The auxiliary point PH is determined based on the last contour point PE, the radius R and the end point PN.
- On a straight line from the auxiliary point PH to the end point PN
If you program the Z coordinate in the departure function, then the tool moves simultaneously in three axes from the auxiliary point PH to the end point PN.
