ABSTRACT:
A system and method of tool path processing is taught which offsets a tool path from a given geometric sequence, avoiding tool interference and accounting for coincident tool paths. It guides a numerically-controlled machine tool in the manufacturing process. In accordance with the present invention, a computer-aided-manufacturing system defines or allows definition of a pattern to be machined by a tool having an offset, analyzes the pattern for points of intersection, breaks down the pattern into contiguous segments between points of intersection, structures a list of the segments, ordered between intersection points, defines tool path chains, responsive to the list; validates the tool path chains to define valid tool paths, and, guides the movement of the tool along a valid tool path.
