DIAGNOSIS OF TOOL WEAR WITH A MICROCONTROLLER

Tool wear monitoring is very important for economical reasons. In this paper a very economical solution is presented. The idea is to use easily available microcontroller based hardware, which is very cheap due to mass production. The cheap hardware is combined together with sophisticated software. The use of regression analysis techniques together with fuzzy logic in order to overcome the challenges in tool wear monitoring forms the basis of the developed approach. The proposed approach is tested with data from drilling tests.
