MEASUREMENT AND SENSING OF CUTTING TOOL WEAR

M. Murugan, V. Radhakrishnan

Abstract

Measurement of cutting tool wear is critical in metal cutting operations. In automated manufacturing, sensing of tool wear is of interest. In single point cutting tools, wear parameters are expressed in terms of wear land width and crater depth, which may not be the ideal or effective parameters to explain the wear related phenomenon in metal cutting. This paper deals with the measurement of wear by considering the three dimensional nature of the wear phenomenon. For this a special relocating fixture was designed and realized and the land and crater wear profiles were plotted in a single setup. From these profiles it was possible to compute other parameters, which could be used for wear quantification. For sensing tool wear, a pneumatic method of wear monitoring has been attempted. This paper gives the details of the measurement set-ups, measurement procedures, new parameter evaluation and their relationship with standard parameters as well as other wear related effects in metal cutting.
