Abstract
Two dimensional (2D) orthogonal cutting experiments using diamond-coated tools were conducted with forces and tool-tip temperatures measured by dynamometry and infrared thermography, respectively. The objective of this study was to analyze cutting parameter effects on process behavior in diamond-coated tool machining. Special cutting tools and workpieces were prepared to realize orthogonal cutting. The specific cutting energy and the ratio of forces in the normal and cutting directions increased with decreasing uncut chip thickness. The tool temperatures generally increase with the uncut chip thickness. The specific cutting energy decreases slightly with the increase of the cutting speed. The tool temperatures increase significantly with the cutting speed, but level off at a higher cutting speed, 5 m/s. The effect of increasing the edge radius was to increase the specific cutting energy and the force ratio. The tool temperatures were lowest at the middle edge radius value and increase at both the smaller and larger edge radii.
