Experimental validation of numerical thermal models for ...

Aug 11, 2008  The purpose of this work was to experimentally validate numerical thermal models of the dry grinding manufacturing processes. Two models were developed: one for low depths of cut that ignored the effects of the contact angle, referred to as the shallow grinding model, and one for large depths of cut that included the effects of the contact angle, referred to as the deep grinding model.
