Abstract

High speed dry turning is one of the most important themes in ecological manufacturing. But in conventional turning style, it is difficult to reduce cutting temperature because the cutting edge is contacted to the workpiece continuously. Then in mill-turning, high speed face milling is applied for machining of cylindrical parts, and it is possible to reduce cutting temperature by using high speed-interrupted-small depth cutting method so as high speed end milling. In this study, we have made clear the ability of mill-turning, and optimum cutting conditions for tool life. So we developed the prototype cutters for mill-turning, and tested their performance.

Key words: high speed turning, dry turning, mill-turning, multi-tasking machine
