Departure function DEP LCT

Application

With the NC function DEP LCT, 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 Cartesian 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.
