Cyclic dwell time with FUNCTION FEED DWELL
Application
FUNCTION FEED DWELL allows you to program a cyclic dwell time in seconds, such as for forcing chip breaking.

Description of function
The FUNCTION FEED DWELL function is not effective with rapid traverse movements and probing motions.
Use FUNCTION FEED DWELL RESET to reset the recurring dwell time.
The control automatically resets the FUNCTION FEED DWELL function at the end of a program.
Program FUNCTION FEED DWELL immediately prior to the operation you wish to run with chip breaking. Reset the dwell time immediately following the machining with chip breaking.
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.
