Abstract

Advanced grinding processes include relatively new grinding processes such as Creep Feed, HEDG and VIPER grinding. These processes are more productive than conventional grinding ones as a result of favourable process kinematics. Proper understanding of grinding forces can be useful in designing grinding machine tools and fixtures. Additionally information on specific energy helps in selecting process parameters for achieving optimum output. In the present paper, analysis of the effects of process parameters, tribology, work material and auxiliary equipment on grinding forces and specific energy has been carried out. Existing models have been critically analysed and Werner's specific force model was found to be quite promising for advanced grinding processes. It was found that under specific boundary conditions and environment, similar to advanced grinding processes, this model estimates grinding forces with acceptable accuracy. The model was further analysed and an alternative and slightly modified one was proposed. The proposed models were validated using experimental data from the literature and good agreement between the calculations and the experiments was found.
