Abstract
A method of evaluating flatness of a two-dimensional area of a surface of an unfinished workpiece prior to performance of a process step in which a prescribed operation is performed on the surface by a tool. A flatness value for the surface is calculated and used either to allow or to disallow the prescribed operation to proceed, and when allowed, uses the flatness value for parameter adjustment.
