The Tool to Model through Micro Strain and Micro Cutting

Abstract

The cutter wear is analised by a single hard fixed particle (inclusion) in brittle material. The shakedown pressure of the inclusion contact is directly proportional to shear field stress of the cutter surface and is function of adhesive coefficient. The deformation modes of cutter surface are shakedown, ploughing or cutting. The hard inclusions are assumed to be spherical with constant radius and their position distribution is taken to be Gaussian. Higher hard inclusions in sliding contact may cut or plough the cutter surface while lower hard inclusions contact cutter surface elastically. It is analyzed the effect of all the hard inclusions contacts and it gives quantitative prediction of wear coefficient.
