Advantages of the CCD camera measurements for profile and wear of cutting tools

Abstract

In our paper we prepared an evaluating study of which conclusions draw mainly two directions for our fields of research. On the one hand, this means the measuring of fix, standing workpieces, on the other hand this means geometrical measurement of moving tools. The first case seems to be solved in many respects (in general cases), but the second one is not completely worked out according to the relevant literature. The monitoring of tool wear, the determination of geometrical parameters (this is mainly in case of gear-generating tools) is not really widespread yet, mainly, if optical parameters have influence on the evaluating procedure (e.g. examination of profiles of grinding wheels). We show the elaboration of a process for the practical application of measuring techniques performed by image processing CCD cameras on the basis of wearing criteria of different cutting tools (drilling tool, turning tool). We have made a profile and cutting tool wear measuring program. © 2005 IOP Publishing Ltd.
