Abstract
The modification of the cutting edge micro shape by wet abrasive jet machining is utilized to increase the performance of cutting tools by means of productivity and tool life. However, for numerous cutting processes the optimal micro shape of cutting edges is still unknown. In this regard, the paper deals with a method to predict optimized cutting edge micro shapes using FE-Simulation. The method includes the consideration of the local process conditions like radius dependent cutting speeds in drilling processes depicted by the example of drilling a nickel-base alloy. In this paper first simulation analyses are compared to experimental investigations. In addition, predictions of the mechanical loads dependent on the applied cutting edge micro shapes are presented.
