Method for approximately reproducing the surface of a workpiece from CAD data in a multiple milling process, involves breaking down first approximation of the shape into smaller parts which are milled accordingly

摘要

Approximate reproduction of the surface of a workpiece by construction of its contours in a simple manner. According to the method in a first step the body is approximated as a whole. The starting body is then subdivided into a number of partial volumes, so that for reproduction of the workpiece in a second approximation step the partial volumes are selected for which a step involving an analytical reproduction of the milling volume which stretches from the filling cutter along a cover milling path is established. Independent claims are included for use of the method for multiple milling of a workpiece, especially for five milling steps, to a system for reproduction of a workpiece surface, a computer program and a computer for running the program.
