Abstract
It is well known that grooving wear which is formed on the end cutting edge is extremely harmful to surface finish in turning. Although much effort has been devoted hitherto to clarify the mechanism of grooving wear and to prevent it, no appreciable solution or remedy has been found. In this report, the influence of gaseous environment and the physico-chemical properties of tool and work materials on the grooving wear have been analyzed experimentally, and the findings are as follows:
(1) The gaseous media have a remarkable effect on the wear process.
(2) The groove formation is accelerated with an easily oxidiable tool material.
(3) The grooving wear is little formed with a tool material on which a stable oxide film is formed during cutting.
In other words, the major cause of grooving wear is the chemical reactions on the tool face, and from this a practically acceptable remedy against grooving wear has been deduced.
