G71 type I and type II cycles
Earlier, there was only type I cycle (I think so). Type II cycle was introduced to take care of undercuts or pockets along the length of the job. The control identifies these two cycles on the basis of whether only X is programmed in the P block, or both X and Z are programmed. Earlier, Z was not allowed in the P block (in type I cycle). My question is that, if we program both X and Z in the P block, for a job which has monotonic increase in both X and Z (i.e., has no undercuts, hence suitable for type I cycle), what will happen?
radius compensation in Type II G71 turning
Fanuc 0i manual says in G71 type II section:
"The offset of the tool tip radius is not added to finishing allowances. In turning, the offset of the tool tip radius is assumed to be zero."
Does it mean that radius compensation (G41/42) is not possible in type II turning?
