<p>A method of eliminating surface gouging in computer-aided control of cutter paths, comprising the steps of: (a) generating three-dimensional computer images of a surface (22) to be emulated and of a revolving cutter head; (b) imposing an x-y coordinate grid work onto each image and assigning a z coordinate to the cutter depth and surface height for each grid; (c) while digitally moving the cutter head (21) over the emulated surface (23,24), determining the highest sum of z coordinates for each grid within the superimposed area; and (d) using such highest sum as the lowest z coordinate for a cutter reference point at each such digital position of the cutter, the highest sum being adjusted for any difference between the reference point and cutter depth at such highest sum grid. u</p> |
