The Influence of Tthe Grinding Grains Shape and Orientation on Performance of Coated Abrasive Tools

Abstract

The issues of the influence of the orientation and shape of grinding grains of coated abrasive tools on their basic performance characteristics are considered in the article. The advantages of machining with flexible grinding tools are listed. The features of the abrasive grains contained in tools on a flexible basis are presented. The low efficiency of using standard tools is justified. A method is described for increasing the efficiency of the grinding process with tools on a flexible basis due to an integrated approach to the design of new tool designs. It is proposed to use abrasive grains of a given shape and oriented in a certain way relative to the surface of the tool base. The main stages of work related to the development of new tool designs and studies of their operational characteristics are presented. Experimental data of the dependencies of cutting capability, wear, temperature in the cutting zone, power spent on cutting, and the cut surface quality on the shape and the orientation angle of grinding grains are presented. Practical recommendations for the application of tools containing in their structure certain varieties of grinding grains are proposed.
