I would enjoy, given the opportunity, attempting to set up LCNC on a turning center with a main spindle, subspindle, and multiple turrets. These are very efficient machines for making turned parts (and generally have live tooling as well). I believe one typical way of controlling these is with a separate G-code program for each turret, with interlock M-codes to synchronize when doing things like pinch turning. With an upper turret and a lower turret, either turret can work on either spindle, but you have to decide which operations will be performed by which turret. So in the CAM software you drag your operations around to try to balance the machining time for each turret, and get the syncs correct so you grab your part with the subspindle before you cut it off, then move it off and machine the back side with one turret while starting on the face of the next part with the other turret.
Don't know which kind of multispindle machine you were thinking of... -- Ralph ________________________________________ From: andy pugh [bodge...@gmail.com] Sent: Tuesday, May 24, 2016 1:59 PM To: Enhanced Machine Controller (EMC) Subject: [Emc-users] Multi-spindle machines Has anyone here ever wanted multi-spindle support in LinuxCNC?
