Need Help!- retract rates

[pcb-101]

i am trying to figure out how to control the retract rate on a Haas VF 2YT

I'm not sure about HAAS, but Mistubishi and other controllers do it through
their on-board system parameters.

My guess is that HAAS might have similar system level settings

What retract rate? From the bottom of a hole during canned cycles?

On a lathe?

Usually, the retraction is rapid in drilling cycles, at feedrate in boring cycles/tapping, and at multiples of feedrate (up to 20xF, depending on parameter settings) in rigid tapping. This is for Fanuc. On Haas also similar things might be there.

If you are meaning the tapping retract rate it is Setting 130 which can be 0 or 1 for a normal retract rate. 2, 3 etc retracts 2 or 3 times as fast. Alternatively you can have a Jvalue in the G84 command and this over-rides whatever is in Setting 130
