Hi,
I recently buy a new lathe with fanuc oitd,
the same program whit g71 roughing type 2 (undercut) :

runned on 0itc take 9,30 min

runned on 0itd take 11,30 min

take more time on 0itd because it going to cut air!

The lathe are quite similar and i use same cutting speed

Anyone have similar experiance???

Thanks all
