Abstract

Grinding efficiency is one of the most important considerations in the selection of grinding operation conditions because it has a significant impact on the productivity, quality, energy consumption and cost of production. Focusing on the core issues of grinding process, the paper presents some fundamental research findings in relation to grinding material removal mechanisms. The grinding efficiency is analysed by considering the rubbing, ploughing and cutting three stages of a single grit grinding process. By analysing the features of acoustic emission in single grit grinding tests, an evidence based scientific foundation has been established for monitoring grinding efficiency using acoustic emission. Accordingly, the energy consumption in the grinding is considered with the grit shape. Following the discussion of the models of temperature elevation and thermal stresses in grinding, the paper provides a logic depiction that explains why acoustic emission in grinding can be used for grinding thermal performance monitoring. As a result, the paper introduces a novel acoustic emission monitoring method that is capable to monitor grinding temperature and grinding wheel wear status.
