Abstract

A machine featuring a treatment tool that grinds a surface to a desired profile, imparts a desired roughness to that surface, and removes contamination from the surface, the machine configured to control multiple independent input variables simultaneously, the controllable variables selected from the group consisting of (i) velocity, (ii) rotation, and (iii) dither of the treatment tool, and (iv) pressure of the treatment tool against the surface. The machine can move the treatment tool with six degrees of freedom.

Claims (2)

1. A machine comprising a treatment tool that, in a single operation, grinds a surface to a desired figure, imparts a desired roughness to that surface, and removes contamination, said treatment tool comprising a contacting surface configured to contact the surface to be ground and roughened, said contacting surface (a) having a similar hardness as the surface to be ground and roughened, and (b) having a toroidal shape such that contact of said toroidal surface with a flat surface defines a circle, said machine further comprising a means for imparting dither to said treatment tool.

2. The machine of claim 1 , further comprising means for controlling at least one of amplitude and frequency of said dither.
