The Failure of Metal Cutting Tools at Tool/Work Disengagement

  • Chapter
Proceedings of the Thirtieth International MATADOR Conference

Abstract

The paper presents recent findings obtained from our finite element modelling of a metal cutting tool engaged in an intermittent cutting operation. Finite element models have been developed for different configurations of the tool, the chip generated, and the workpiece. These have been studied for various cutting conditions at both the steady state cutting and tool/work disengagement stages. Stresses generated on the tool/chip contact region have been thoroughly analysed. The effects of other parameters, such as tool/chip contact length, deformation of the cutting tool, etc. on tool failure have also been examined. The stresses generated within the cutting tool, and their effect on tool failure have been investigated for both steady state and the tool/work disengagement stages of an intermittent cutting operation.
