Abstract:
A method for forming a layer element of material having a desired thickness, high thickness uniformity, and high surface integrity from a working layer element having thickness non-uniformities and thickness greater than the desired thickness, comprising the steps of:a) generating a first two-dimensional map of values of actual thickness of said working layer element; b) generating a second two-dimensional map of values of material to be removed from said working layer element by subtracting the value of said desired thickness from each of said actual thickness values; c) programming a magnetorheological finishing system with said map of values of material to be removed; d) mounting said working layer element onto said magnetorheological finishing system; e) indexing said working layer element to said system; and f) removing material by magnetorheological finishing from said working layer element in accordance with said map of values to leave said a residual layer element having said desired thickness, high thickness uniformity, high surface integrity.
