Analysis of processing parameters for flat grinding: АНАЛИЗ ПАРАМЕТРОВ ОБРАБОТКИ ПРИ ПЛОСКОМ ШЛИФОВАНИИ

Abstract

In the article presents simplified dependencies for determining the main parameters of
grinding, which make it possible to scientifically justify the discovery of complex kinematic and
physical laws of the grinding process. On the basis of the obtained dependences, a comparison of
multi-pass and deep grinding by roughness of the treated surface and processing capacity was
carried out. It is shown that the transition to the area of deep grinding allows simultaneously
increasing the productivity of processing and reducing the height of microroughness on the treated
surface. It has been theoretically proved that the effect of deep grinding is caused by a significant
excess of the total area of scratches, scratches, formed on the surface to be treated, above the
nominal surface area of the treated surface. As a result of the study it was found that the actual
grinding depth becomes larger than the nominal grinding depth established on the machine limb, so
for the normal course of the grinding process the actual grinding depth should be less than the
protrusion height of the grains above the level of the ligament of the circle.
