Abstract

All available information on diamond abrasive machining thermal processes simulation has been obtained with the suggestion that the materials to be ground are of uniformed  structure, and doesn’t take into account presence of the articles’ technology strain defects. Study of causes of forming cracks as  grinding defects was made within the theory of strain-stressed state of a part’s surface layer qualitatively or experimentally in every single case. This article contains analysis of crack forming causes when grinding materials and alloys apt to this kind of defects. It’s shown that crack-forming intensity is determined by presence of various material heterogeneities to take place at the surface layer during the detail making. Functional dependences are obtained as for technology parameters with crack-forming conditions taken into account, for the process of grinding materials apt to this kind defects to happen. When choosing machining conditions and tool capabilities, one is to take into account heat flow limits to produce when grinding to prevent forming strain defects into cracks.

With the functional dependences between physical-mechanical properties of materials machined and general technology parameters determined, technology criteria were worked out to control a process of  defect-free grinding.
