摘要
The prediction of tool wear in conventional deep-drawing is accomplished using the finite-element method. The distribution of tool wear on the draw-die profile is obtained and compared to industrial observations. This is achieved by proposing a semi-empirical wear model in which the tool wear is a function of both the normal pressure and the relative velocity between the sheet and the tooling. Furthermore, a parameter study has been carried out to see the effect on the tool wear when changing selected parameters, for example the blank thickness and the strain hardening.
