Tool Life Experiments and Vibration Assistance in Regard to the Machining of CFRP

Abstract

Molding techniques and manufacturing of components consisting of fibre reinforced polymers are mostly controlled processes. However, finishing of such materials can even today still be seen as a very challenging and not completely controlled process, which often has a non-satisfying machining quality as result. This paper deals with different topics in the field of machining FRP. On the one hand, it deals with ideas for possible evaluation mechanisms in order to classify the resulting machining quality of FRP when machining with a cutting edge. Referring to this, a framework for the definition of an international standard in measuring machining quality on FRP parts is presented. On the other hand, a possible assistance system with the aim to improve the demanding cutting process as well as a tool life experiment, are investigated. The results of these practical experiments are presented and evaluated.
