Generating spherical surfaces | Cutting Tool Engineering

When the tool is set at an angle other than the axis of the rotary table and the part is rotated under the tool, a spherical surface is generated. The boring head is tipped at an angle that represents the chord of the desired spherical segment. A single-point cutting tool is applied and, depending on whether the form is concave or convex, the ...

An Introduction to the Optics Manufacturing Process

Loose abrasive grinding uses inverse spheres of the same radii ground together so that the hills and valleys on the optics will wear away to produce a true sphere. Slurry flows in between the blocked parts and the spherical tool to keep the parts cool and wash away debris created during the grinding process. Polishing
