INFRARED TEMPERATURE-MEASUREMENT ON DIAMOND-COATED TOOLS DURING MACHINING

In the presented paper a measuring technique is described which can be used to measure the cutting temperature of CVD diamond coated tools i n continuous machining. This technique is to be used in researching th e correlations between cutting parameters, temperature distribution in the zone of cutting and machined workpiece surface. The optical prope rties of the coating are tested using infrared spectroscopy; those of the measuring probe are tested using black-body techniques. The emissi on spectra are qualitatively recorded in the machining of several work piece materials. Optimizing the mechanical and optical properties of t he measuring probe, the aim is for further research to set up the cutt ing parameters for machining Fe-based alloys, so that the real tempera tures in the zone of cutting are below the critical diffusion temperat ure of diamond.
