三次元NC工具研削により創成されるフルート断面形状の解析

抄録

It is difficult to theoretically obtain three-dimensional flute configuration, as well as cutting edges of cutting tools such as endmills and drills, which are produced by disk or cup grinding wheels, because the configuration is an envelope generated by three-dimensional motion of the wheel. This paper deals with a theoretical analysis concerning this problem. For this purpose, a vector analysis which makes use of the rotational transformation tensor was adopted. The results of the simulation analysis carried out here yield a clue for improving the NC programming for tool grinding. The results of the analysis were also proved valid by some experiments.
