Abstract
This report is only the introduction of the project to establish the machining standards for various important metals specified by the Japanese Standard. The major items of the test are selection of carbide grade, tool shape, speeds, and feed for turning typical five grades of plain carbon steels, and close investigation of the tool life from the viewpoint of both flank wear and crater.
According to the test result, crater wear is the most serious problem in turning the carbon steels. Therefore, every effort should be made to control crater wear in selecting the best carbide grade, tool shape, cutting conditions, etc.
