Abstract: A method and system for generating a path to be followed by a cutting tool i n a milling situation. Using a novel geometric concept suited to a milling situation called "focal areas," a toolpath is generated in which the cutting tool remains in constan t contact with material to be cut, thus minimizing wear and shock loading of the tool. In addition, the toolpath is optimized so as to trace a short path, thereby minimizing cuttin g time. The toolpath generator is particularly useful in high speed milling applications .
