Method and apparatus for creating tool path data for a numerically controlled cutter to create incised carvings

摘要

A 2-dimensional drawing of closed shapes and/or letters is processed for incised carving with a conical tool. Each closed shape is processed independently to generate a plurality of connected cutter paths. While carving each path it is necessary to change the tool depth so that the edge of the tool at the surface of work remains tangent to two sides at all times. A recursive process is used to handle parts of the work where the cutting path splits.
