Abstract:
1. A method for registering machine tool and profilometer coordinates, said machine tool defining a C-axis having a zero position, said method comprising the steps of: 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 said centroids of said first cut features; measuring angle θ 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 said centroids of said second cut features; and determining a center of the circle, said center being the machine tool center in profilometer coordinates.
