6.5 “ O9101” - WORKPIECE CHANGE-OVER WITH PARTING OFF, WITHOUT EXTRACTION
This is a sub-program that manages the workpiece change-over between spindles working from a bar, for
this reason the cut is made with a parting off tool. This sub-program is used when, working on a bar, the
workpiece is taken onto the back spindle to work on the second part. At the end of the cycle, the push bar
conveyor or the back spindle is used to extract the workpiece with a useful length for machining
