Abstract:
A method for processing the surface of a workpiece by removal of material with a tool, wherein the tool is led along paths over the workpiece, whereby material getting into a cutting range of the tool is removed for generating a desired surface, said method comprising the steps of:repeatedly calculating an inclination and a tilting angle for the tool along the paths of the tool under the conditions that: (a) the cutting range at the inclination and tilting angle contacts the desired surface of the workpiece at two points (b) an area of tolerance exists being defined as a continuous area within which a distance between the desired surface and the cutting range of the tool lies within a given acceptable mismatch, wherein the inclination and tilting angles are calculated for each of a plurality of locations on the paths by numerically varying a position of at least one of the points until a width of the area of tolerance reaches a maximum value while keeping the distance within the given acceptable mismatch, and positioning said tool along the paths using the calculated inclination and tilting angles.
