Abstract
The present invention provides a method and apparatus for the automated machining of three dimensional objects of complex and unique geometry. A computer acquires data describing an object and its surroundings and then guides a milling machine in the fabrication of the reproduction. The present invention discloses a method for preventing tool paths generated in a computer from erroneously intersecting with surface patches representing an object to be machined. The present invention also discloses methods for optimizing tool path step lengths, machine tool commands, and tool path scallop heights. In addition, the present invention discloses a method for fixturing a workpiece material to be shaped into a reproduction of a object.
