Hi,
I would like to know if there is a way to use radius compensation in cycles like G71 G72, my machine ignores the compensation only works with G70.
Thanks

According to the Fanuc 21iT-B Operator's Manual:
11. Tool nose radius compensation cannot be applied to G71, G72, G73,
G74, G75, G76, or G78.
Compensation is often okay with G70, the finishing cycle, so one way to do it is have U and W values that leave on enough material in the G71/72 for a compensated finishing cut.
An open mind is a virtue...so long as all the common sense has not leaked out.
You are not alone.
I use a Haas lathe which is similar to Fanuc and I finished up doing the roughing for a profile using G72 with the tool radius approximated in my code. Then I wrote code for the correct profile and ran two separate finishing cuts using compensation but not using any canned cycle. Tedious but it worked.
