Fanuc-18T G73 Cycle definition

[jdr1961]

When defining the part profile for the G73 Pattern Repeat cycle, is it okay to use the angle, chamfer and radius addresses (,A ,C ,R) or must it be done using G1, G2 and G3?

The machine is a Hardinge GT-27 lathe with Fanuc-18T control.

Thank you for any help!

According to the 18T-B manual, you can use chamfering and/or corner rounding, just not in the last block of the definition.

On 0i control, it is not permitted. I was under the impression that the standard G-codes work the same way in all control versions. At least in this case, there is difference (or do we have to again interpret the language of Fanuc manuals!). From 0i TC Operator's Manual (Section 13.2.8, page 158):
8. The blocks between the sequence number specified by P and Q on the multiple repetitive cycle must not be programmed by using "Direct Drawing Dimensions Programming" or "Chamfering and Corner R".
