Abstract:
A method of processing a workpiece using a rotary tool, comprising the steps of:causing the rotary tool to enter a processing surface of the workpiece, the workpiece having a length in an X direction, a width in a Y direction, and a thickness in a Z direction, by moving the rotary tool and the workpiece relative to each other in the X direction, the Y direction, and the Z direction, so that the rotary tool obliquely enters the processing surface along an initial X, Y, and Z moving direction to a depth in the Z direction; carving the workpiece to produce a carved region by a series of iterative cutting paths by first moving the rotary tool and the workpiece relative to each other in a direction opposite to the initial X and Y moving direction during the entering step while keeping the depth constant, wherein each of said cutting paths in said series of iterative cutting paths is a curved path; and moving the rotary tool and the workpiece relative to each other incrementally to a position for a next iteration of said iterative cutting paths.
