Abstract

paper, and the author is glad to be able to report preliminary investigations along this line under way. Such investigations are steps along the path toward the eventual goal mentioned by Mr. Lucht, and shared by the author, of placing the prediction of machinabilit.y and the design of cutting tools on a sound mathematical and engineering basis.Mr. Oldacre questions the mechanism of chip formation dis-AS cussed in the paper. However, his conclusion that -must J J ' AX approach infinity because AX approaches ze…
