Parameter Description
Linear infeed/
Degressive infeed
This function key is used to switch between "linear infeed" and "degressive infeed". "Linear
infeed" means that roughing always takes place at a constant depth of cut, and the internal
infeed calculation is designed so that the value for the "max. infeed depth" (m1) is not
exceeded during the entire thread cutting operation. "Degressive infeed" on the other hand
means that the volume of cut is kept constant throughout the entire thread cutting operation.
In this case too, the value for "max. infeed depth" (m1) is observed throughout the entire
operation.
Number of thread starts The number of thread starts is defined here.
Softkey
This softkey is used to select remachining or thread recutting (thread repair).
Thread cutting
The machining sequence is as follows:
1. Starting from the current axis position, the start position for the thread (d1/z0) is
approached in rapid traverse.
2. This is followed by infeed by the first depth of cut.
3. The controller then waits for the next zero mark from the spindle encoder in order to start
the axis movements (longitudinal axis and/or transverse axis) (depending on the thread
geometry).
4. Once the end position for the thread has been reached in both axes, the tool is withdrawn
from the workpiece in rapid traverse.
5. The start position for the thread is then approached in the longitudinal and transverse
axis in rapid traverse, observing a clearance distance.
6. Infeed to the next depth of cut.
7. Wait for the next marker pulse from the spindle encoder to start the axes...
This process continues until all cuts have been completed. An additional finishing cut to
smooth the thread is then performed and the start position for the thread is approached in
the longitudinal and transverse axes.
8. There is now a choice of 2 options:
– Machining is now complete and the "Execute" screen can be closed with the "Abort"
softkey.
– If you wish to continue machining the thread, e.g. if thread finishing is required, press
NC Start again.
