Predicting of tool wear for hot metal forging - an overview and suggested new approach

摘要

The process of tool wear is a very complex phenomenon and as experience has shown, it is not easy to describe it mathematically either by phenomenological models or by empirical models, using classical statistical tools. Due to the complexity of the problem, predicting tool wear even today presents a great challenge. Better wear prediction would also mean lower production costs, since unexpected tool breakdowns (failures) can increase costs by up to 30 percent per forging unit. An overview of wear models for predicting of tool wear in hot forging are presented in the paper and applications of the recently introduced new approach of tool wear prediction on industrial tools are given.
