Programmed Run-In And Run-Out Path (Dits, Dite) - Siemens Sinumerik 840D sl Programming Manual

10.10.2

Programmed run-in and run-out path (DITS, DITE):

The DITS and DITE commands can be used to program the path ramp for acceleration and
braking, providing a means of adapting the feedrate accordingly if the tool run-in/run-out is too
short:
● Run-in path too short
Due to the collar on the thread runin, little room is left for the tool start ramp. This must
therefore be specified shorter via DITS.
● Run-out path too short
Because of the shoulder at the thread run-out, there is not much room for the tool braking
ramp, introducing a risk of collision between the workpiece and the tool cutting edge.
The tool braking ramp can be specified shorter using DITE. However, there is still a risk of
collision.
Run-out: Program a shorter thread, reduce the spindle speed.
