In a sheet metal forming process, lubricants or hard coatings are applied on the tool surfaces for the purpose of friction reduction. Friction coefficient is not a constant value during a metal forming process under multi-cycle loading conditions, due to the degradation of lubricants or hard coatings.
The functional module 'Tool-Life' is developed by using a unique interactive friction modelling technique Read More to prdict the evolutions of fricton coefficient and the breakdown of the lubrication or hard coatings, under multi-cycle loading conditions.
The innovative work generated from 'Tool-Life' was awarded the best paper prize in the 4th international Conference on new Forming Technology, ICNFT 2015. Glasgow, UKTool Life
