US 6,591,159 B2 · Method of making tool path

Abstract

A method of making a tool path, wherein a shape to which an object surface is to be processed and processing conditions are inputted, and a processing region is designated on the processing region, and a tool path on the processing region is calculated on the basis of the reference lines. When the number of the processing region is one, a tool escaping expansion region is added to a terminal end in the picking direction of the processing region, or a tool approaching expansion region is added to a starting end in the picking direction of the processing region. When the number of the processing regions is not smaller than two, a tool escaping expansion region is added to a final end in the picking direction of the processing region precedingly, and a tool approaching expansion region to a starting end in the picking direction of the processing region posteriorly.

A method of making a tool path, comprising the steps of:

designating processing regions on a surface to be processed;
designating reference lines on the processing regions;
calculating on the basis of the reference lines a plurality of tool paths on the processing regions;
selecting at least one of the adding of a tool approaching expansion region of which a distance measured from the surface to be processed becomes larger as the expansion region gets away from the processing region to a starting end in the picking direction of the processing region, and the adding of a tool escaping expansion region of which a distance measured from the surface to be processed becomes larger as this expansion region gets away from the processing region to a terminal end in the picking direction of the processing region;
and
calculating the tool path on the expanded region.
