I use Dolphin Partmaster for mill but hardly for lathe, for lathe most of what I do I can get by with using the wizards in Mach 3.
These will be updated shortly so you can add to them, i.e stack them up so you can do a face operation, then turn, then screwcut.

Ron Ginger who's in charge of Wizards reckons he'll have them done for the CNC show in the US in June or July.

Partmaster is a two part program, CAD and CAM. CAD absolutely sucks, it's terrible and not intuitive at all. CAM is very good and if you bring files in as DXF's it works well.
