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 is 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 normal vs. cutting force ratio increase with the decrease of the 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 levels off at a higher cutting speed, 5 m/s. The effect of increasing the edge radius is to increase the specific cutting energy and the force ratio. The tool temperatures are lowest at the middle edge radius value and increase at both the smaller and larger edge radii.
