Abstract
Technology for milling selected portions of a workpiece by a cutting tool of a numerical control machine is described. The described technology provides methods and apparatuses for milling areas of a part so that more aggressive machining parameters can be used in the toolpath, thereby resulting in reduced machining time and load. The technology creates a series of toolpath contours where arcs in the toolpath contours are non-concentric with arcs in other toolpath contours. The selected portions of the workpiece are milled by moving the cutting tool in accordance with the toolpath.

1-9. (canceled)
A method for milling selected portions of a workpiece by a cutting tool of a numerical control machine, the numerical control machine having associated therewith a processor and a memory, the method comprising:
- receiving one or more chains of curves inside a workpiece representing a toolpath for milling selected portions of a workpiece;
- replacing at least one circular arc in the toolpath with a sequence of curves containing a new circular arc closer to the boundary of the workpiece;
- and
- milling the selected portions of the workpiece by moving the cutting tool in accordance with the toolpath.
