Mori SL-25 programing

[mschmitz88]

I am running an mori sl-25 with a yasnac I80L controll. I am getting an error "Faults in finished shape" with this program below once it gets to the G71. Thanks for any help

Done.

Just curious... what does this part look like? Can you share a drawing?

It looks to me like X has both decreasing and increasing diameters within the finish shape definition. If this is true, you need an R1 in the G71 block to specify a type II shape. Also, the shape definition looks "strange".

making it a type II canned cycle may help make it run but the profile seems very wrong to me.
if this is an OD turning operation the tool moves like this....

G0 X2.6 Z0 (rapid)
G1 X-.03 F.015 (face cut)
G0 X2.65 Z.1 (rapid)
G1 Z-1.35 F.015 (feed to Z-1.35)
X-.02 (feed to ~center)
X2.355 F.004 (feed to X2.355)
G3 X2.45 Z-1.39 R.04 (CCW radius to X2.45 Z-1.39)
G1 X2.48 Z-1.44 F.003 (feed to X2.84 Z-1.44)

when the tool is at Z-1.35 it then goes to X-0.02 which will part off the job when the G70 runs (using a WNMG insert!)
assuming it even gets that far with the tool still in one piece. the roughing won't work with that profile.
