Abstract
A method for registering machine tool and profilometer coordinates, wherein the machine tool defines a C-axis having a zero position, C=0, comprises loading a sacrificial workpiece into the machine tool; cutting several first features in a surface of the sacrificial workpiece and producing a linear machine tool motion across the workpiece; determining the centroid of each first cut feature; fitting a line to the centroids of the first cut features; and measuring angle θof the line relative to the C-axis zero position. The angle θis the departure in profilometer coordinates from the C=0 line. The method includes moving the machine tool to a fixed radius; cutting several second features in a surface of the sacrificial workpiece and producing a circular machine tool motion across the workpiece; determining the centroid of each second cut feature; fitting a circle to the centroids of the second cut features; and determining a center of the circle. The center of the circle is the machine tool center in profilometer coordinates.
