Abstract

The influence of various combinations of punch and die materials, such as different carbide grades, and also the cutting radius on tool wear is the aim of this investigation. The numerical analysis results are supported by the relevant experimental evidence to validate the main model assumptions such as assumed material flow stress curve and the damage criteria. Taguchi method is utilised to effectively model and analyse relationship between process parameters. Roll-over and burr formation for a given punch-die clearance and cutting radius have been discussed and analysed in terms of tool wear reduction for different materials.
