Generating spherical surfaces | Cutting Tool Engineering

01/03/2013· A unique manual milling method is available for generating geometrically true spherical surfaces. This technique can be used to machine convex and concave spherical surfaces. Other than the milling machine, the only tools needed are a boring head and a rotary table. If you have a CNC lathe or mill, this is really just an academic exercise. The technique is interesting in that it is self-correcting and self-proving, which is not true of CNC equipment. If you don’t have any CNC ...
