Abstract:
A method of guiding a tool having a working portion, to machine a work piece of a prescribed shape from a material block, comprising the steps of:moving the working portion of the tool along a first guide path extending along an essentially planar guide surface of said block; intersecting said first guide path at a first point on an axis of the tool during said moving step, such that said axis is at an orientation with respect to said guide surface; and moving a second point on said axis of said tool, which is located at a predetermined distance from said first guide path, along a prescribed second guide path; and wherein said first point is moved along said first guide path at a uniform speed, and wherein said second guide path is represented by an assembly of approximation curves that approximate a portion of the prescribed shape such that the third derivative of said second guide path with respect to time is defined.
