Abstract

The importance of surface and edge quality of cemented tungsten carbide inserts to increase tool life motivates a detailed study of the influence of grinding parameters on these factors. The reduction of friction through more regular surfaces and the strengthening of the edge by the decrease of chipping contribute to reduced forces, wear and to an increase in tool life. Within this context, surface roughness and edge chipping obtained after grinding cemented tungsten carbide inserts with different process conditions (cutting speed, feed rate, dressing feed, abrasive grain size and wheel binder) will be assessed. Due to the large number of variables to be analyzed, a 2k factorial design will be developed for the estimation of the effects and analysis of variances. From the results, it is expected to find the trends of variation of surface roughness and edge chipping as a function of process parameters, as well as their effects. (AU
