Replicapro, if your email will accept a 2 or 3Mb PDF file, I'd be pleased to send you an e-book I have written on rotary 4th axis milling and scanning. You wanna do a human head? I did an entire archbishop. Managing undercuts and other hidden surfaces is covered by multiple cuts, using only 3 axes (X-Rotary-Z) simultaneously, but adopting fresh Y locations to cut again and again using fresh toolpaths from fresh scan data. Actually easier than it sounds. Regards,
