Hi ! Here is the scenario :Im in a LATHE environment and I have a 250mm 9.84inch) long bar with a 30mm (1,18inch) diameter that i would like to clamp short in order to face and center drill (1ST OPERATION (G54) ) and after that unclamp and stick it out 200mm (7.87inch) and use a tailstock center to sustain the extreme side and then starting the turning of the bar with a new WCS (G55) (2ND OPERATION).

To cut it short,IN MASTERCAM LATHE , HOW CAN I USE TWO DIFFERENTS WCS ( G54 and G55) in one setup?
