6.4 “O9100” - WORKPIECE EXCHANGE WITH PARTING OFF
This is a sub-program that manages the workpiece change-over between spindles machining from bars.
For this reason the cutting is performed with a parting off tool. This sub-program is used when, machining
the bar, the workpiece is taken up on the back spindle to machine the second part. At the end of the cycle
the workpiece with the useful length will remain on the main spindle .
