CHOICE OF MATERIAL FACTOR IN ENSURING THE MACHINED SURFACE ROUGHNESS THROUGH SUPERFINISHING PROCESS

Abstract

The evolutions of stresses in mechanical transmissions are not uniform. It was being developed analysis techniques and tests to find the influence of random efforts on the fatigue life, wear, etc. Processed material adopted in the design of products for reasons of durability and reliability, require generally for surfaces of machine parts of great importance(eg. bearings),and require a high-quality surface that is obtained by superfinishing process with tools from composite abrasives. The paper presents mathematical models and graphical dependence of the bearings raceway surface roughness upon the influence of the cutting parameters. There are also presented some recommendations concerning the superfinishing process optimization.
