A bit of both!
All my lathe stuff up til now I've just done manually, so having to use a CAM is new to me and proving to be a bit challenging/frustrating.
Also if I'm reading you right all your wanting to do is surface the face and Pocket some holes.? . . . Or are you trying to replicate what's in the picture with the steps etc.?
If you want to email me the Model and what you want done exactly then I can knock you some code to try and compare.
Regards best Package then out of all you've mentioned then I'd go with dolphin. I've Got BobCad and it's Ok but Dolphin easily matches it and is better for Lathes I think.! . . . I don't have Lathe for Bobcad.
I'm Using Solid Cam now and it blows anything I've used before out the water but it should really for the price plus don't have Lathe portion for that either has I don't have CNC Lathe that works at minute.

I managed to bodge it in CamBam by using the same MOPs as the image in my first post produced, then by adding three polyline rectangles and pocketing them out to final depth starting at the depth the waterline MOPs stopped.
However machining it is proving to be another challenge, as I've discovered the mill doesn't have enough power to spin a 6mm HSS endmill at a high enough feed rate to stop it burning up or stalling, and the figures produced by FSWizard and CNCcalc are widely high so 4mm end mills burn up near instantly, and dropping them to manually calculated acceptable figures makes things painfully slow.
So I need to get some carbide end mills ordered, and try again.
I've attached the solidworks and stl file - Attachment 11010
I'm only interested in the bottom (the pic above has it spun upside down) with the ridge and notch, and spiralling a couple mm into the bolt holes to get a good location for drilling them to depth manually.Last edited by m_c; 15-12-2013 at 10:18 PM.
