Grinding of Steel - A Case Study.

Abstract

A description is given of grinding studies aimed at overcoming a production problem on the dry grinding of hardened steel gears for aircraft gas turbine engines, in which grinding abuse in the form of both a softening and hardening of the steel led to high rejection rates. By using a combination of reduced grinding wheel speed and graded finishing cuts, gears could be produced without showing any signs of grinding abuse. A feature of the grinding was the occurrence of redeposition, and the extent of the microstructural changes in relation to redeposition under different grinding conditions is discussed. Keywords: Ground surfaces, Australia.
