Process Monitoring in Grinding

Abstract The grinding process is characterised by a high number of cutting edges undergoing non-uniform wear, this also typifies a highly non-stationary process. Pure process modelling in order to understand the grinding mechanisms and to predict the work result is difficult. In view of this, several approaches by academia and by industry were made to address this issue. One such approach is the development and implementation of process monitoring in grinding. The work presented in this paper summarises the various elements and approaches in process monitoring during grinding. The paper deals with the relevant quantities that describe the grinding process itself and the ensuing work result. Furthermore the different sensing techniques are introduced to measure the relevant quantities. Finally an overview is presented as to the strategies and techniques involved in the interpretation of the measured data and the subsequent control action initiated in order to close the process control loop.
