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?
