Influence of Abrasive Grain Geometrical Characteristics on the Grinding Quality

In the engineering industry grinding is mostly the final operation of the production process, therefore it should provide for the necessary surface quality, dimensional accuracy, and the required geometric shape of a product. This paper reveals how raw material grit, abrasive grains shape, ordering of grains influence the efficiency of the grinding wheels. The implemented research let us conclude that the shape of the grain has a significant influence on performance characteristics of abrasive tools. The choice of a certain shape and orientation of grains depends on the particular task and the desirable result of the process. (C) 2017 The Authors. Published by Elsevier Ltd.
