Thank you for your reply. With this I am able to move the stock keeping the left chuck active, but I am unable to specify the right chuck clamp location. Any idea how to do that? EDIT: I just stumbled upon the "Chuck" option in the lathe toolpath menu. I am now able to do what I wanted to. I will ask again if I need any help. Thank you so much!

Hello guys, This is my first time posting here, and I am a real beginner when it comes to Mastercam. I'll try to make it as easy to understand as possible. First, some basic info: Software : Mastercam X6 (Japanese Lang.) OS : Windows 7 SP1 (64bit) Machine : Nakamura Tome Lathe (Dual spindle, dual upper turrets) Contoller : FANUC POST : Custom-made at the time of software introduction The part to be machined: A long cylindrical bar, which may be 500 to 2000mm long. It is to be machined first by holding in the left chuck only, and then it is pulled out little-by-little and machined whilst holding between both the chucks. Finally, it is held by the right chuck only and completed. The machining process includes face turning, center drilling, OD turning, and multiple grooving operations. What I tried: I was able to do the first stock advance, and the corresponding processing. When I tried to do the stock transfer, the active spindle automatically changes from left to right. How can I stop this changing of the active spindle at every stock transfer, and have it change only at the last transfer? *I could not find anything in the settings dialog (my understanding limited by my level of Japanese). I'd be extremely grateful for any guidance Loading gif
