Patent ID: 8880212

Claim:
A method performed by a milling device for milling selected portions of a workpiece using a cutting tool of a numerical control machine, the numerical control machine having associated therewith a processor and a memory, the method comprising: receiving a main toolpath, the main toolpath comprising two or more cuts; computing one or more transition toolpaths, each transition toolpath defining a transition area intersecting one or more of the cuts of the main toolpath; connecting the completion of one cut to the beginning of the next cut with one or more connecting moves such that each connecting move is substantially inside one or more of the transition areas wherein the cutting tool is substantially disengaged from the workpiece during the connecting move within the transition areas; and milling the selected portions of the workpiece by moving the cutting tool in accordance with the cuts, transition toolpaths, and connecting moves, wherein the milling includes removing material from a portion of at least one of the transition areas corresponding to one of the computed transition toolpaths.
