Spindle speed variation ssv for chatter control was created by snujcnc

I want to know
Linux CNC can control spindle rpm during operation
Ssv spindle speed variation

This type of function require to control chatter during turning operation

If we rotate spindle 1000 rpm and we program variation 150 rpm then during auto mode running spindle rpm variation should be 1150 to 850 continuous

Any idea how to implement this functionality

If it is CSS or Constant Surface Speed, basically changing the spindle speed based on the perimeter of the material, here is everything on the LinuxCNC site about it:

You should be able to use the siggen component to apply a sine wave offset to your spindle speeds.

Yes. Siggen set up to output a sine wave with low frequency. Maybe the amplitude and frequency adjustable with a pyvcp panel. Use sum2 to add it to your spindle speed command.
