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

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.
