Numerical model for simulating surface roughness in honing process

Abstract

In this first part of the project, state-of-art regarding modelling of machining processes with abrasive stones was studied. In the second part of the project, a numerical model was developed o simalte the surface topography to be obtained in a honinh process, as a function of honing parameters like grain, size, linear speed, tangential speed, etc. In the present model, only one grain having a simple shape was considered. The analytical trajectory of the grain was determined as a result of both constant rotating and reciprocating movement of the honing head. Then, numerical calulations were performed or determine the material that is removed by the abrasive grain form a block of material corresponding to workpiece. From these calculations, surface topography of the block material was obtained and main roughness parameters, both in 2 and 3 dimensions, were calculated.
