Tool-Workpiece Temperature for Continuous and Interrupted Cutting of ASSAB 760 Steel with Dry Machining Process

Abstract

Temperature generated on the tool-workpiece has significant effect on the cutting performance. This paper present the tool-workpiece temperature result recorded by thermal imaging camera with various cutting parameter applied. The machining was done on ASSAB 720 steel workpiece for continuous and interrupted cutting. Generally, as the cutting speed, feed rate and depth of cut increases, the tool-workpiece temperature for both continuous and interrupted cutting will increase. Specifically, cutting speed increase from 250m/min to 350 m/min, tool-workpiece temperature increase about 25% at each increment level. The tool-workpiece temperature increase about 16% when the feed rate increases from 0.1 mm/rev to 0.2mm/rev. While, 27% increment was recorded when feed rate increase to 0.4 mm/rev. With the increase of depth of cut, the tool-workpiece temperature recorded an increment between 50oC to 65oC for both continuous and interrupted cutting.
