Rigid Tapping Feedout Speed

I was wondering if there was a way to create a UDE that would increase the spindle speed and synchronization feed of a rigid tapping cycle when reversing out of a hole. This could save a ton of time when tapping multiple deep holes at zero cost. 


Is there a way to do this and could you provide an example of a way to add this if it is possible?

Fom what I've seen this is controlled by the machine, unless you have a Siemens control, where you can SST1 to specify a retraction speed (param may change depending on exactly which Siemens control you have, and what version it is).

On Mazak machines I've seen you can specify H parameter on G84 (again, this may depend on machine/control version).

Other machines it is not controllable (at least not in the program, there may be a param you can set on the control to boost the retract speed)


I use a UDE to specify this value.

Well if its only on the machine control side I don't my current VMC is capable of this then.

This should be part of the cycle in the CNC control. You cna check the programming manual for a parameter for the cycle, but I doubt there is one. On some controls you can edit the subroutine for the cycle.
