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.
Input
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Change the following contents as needed:
- Tools
- Cutting parameters
- Feed rates
- Clearance height or safe position
- Machine-specific positions (e.g., with M91)
- Paths of program calls
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
