The die-workpiece contact stresses often cause surface scratching in deep drawing. The critical barrier for a scratching prediction is the lack of understanding of the interaction mechanisms among random asperities. This research aims to establish a new approach to enabling the predictive assessment of such scratching by taking into account the crucial effects of random asperities and lubrication which will be capable of capturing random surface asperities, revealing the effects of contact stresses and heat transfer from micro-scale to macro-scale, integrating the asperity-lubricant interaction with the micro wear process by asperities, and thereby exploring the mechanisms of surface scratching.
