1. A method of processing a work item, the method comprising:
- configuring a first finishing surface of a processing machine using a conditioning tool having a second finishing surface;
measuring a contour of the first finishing surface;
using the second finishing surface to process the first finishing surface to reduce a difference between the measured contour and a desired contour for the first finishing surface; and
using the first finishing surface to process a work item to cause the work item to have a surface contour that is equal to or approximates a specified surface contour.

Abstract
A lapping or polishing machine includes a material having a first finishing surface to process a surface of a work item, a measuring tool to measure a contour of the first finishing surface, and a conditioning tool having a second finishing surface to process the first finishing surface to reduce a difference between the measured contour and a desired contour of the first finishing surface.

13. A method comprising:
-
moving a measurement object across a finishing surface of a material of a processing machine for processing surface contours of work items, the material having grooves that cause discontinuities in the finishing surface, the measurement object having a dimension that is larger than a maximum width of the grooves; measuring positions of the measurement object; and determining, using a computer, a contour of the finishing surface based on the measurements of the positions of the measurement object. - View Dependent Claims (14, 15, 16, 17)
