Generating spherical surfaces | Cutting Tool Engineering
Mar 01, 2013 · The spherical surface generation technique can produce a full sphere. A single-point cutting tool sweeps through a circle that has no thickness on one side of the cutting edge. If you think about how a ring of any size smaller than the spherical surface can lay in full contact with the sphere, you can visualize how the cutting action takes place.

Milling Finish: Complete Guide [ Tips, Techniques, and ...
Jan 23, 2019 · When it comes to area finishing, there are two schools of thought on tram and surface finish–either get your mill trammed near perfectly or put it out of tram just a little bit. The considerations are largely aesthetic. If your mill is well trammed, you’ll see equal tooling marks on both sides.
How to machine a hollow sphere - Practical Machinist
May 03, 2011 · Thanks for the interesting ideas. I posted a sketch of the hollow sphere on the OP. Dimensions are not correct, but the idea is there. The two tubes on each end are to be welded on after machining is done. Machining will be done on manual lathe and/or mill. The interior surface can be rough machined.
Surfacing Ball Endmills - Practical Machinist
Dec 19, 2011 · If your after a real good surface finish and you feel the part geometry needs to be surfaced with a ball endmill, a very good alternative is the "flat" ball from LMT Fette. It is basically a ball endmill with a very tiny flat cutting portion on the nose to avoid the zero surface feet at the tip, for example a 6mm dia ball has around a 1mm flat.
Sphere - Wikipedia
A sphere (from Greek σφαῖρα — sphaira, "globe, ball") is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball (viz., analogous to the circular objects in two dimensions, where a " circle " circumscribes its "disk" ). Like a circle in a two-dimensional space,...
