High-performance dry grinding using a grinding wheel with a defined grain pattern

This paper presents the potential of a superabrasive electroplated grinding wheel with a defined grain pattern for dry surface grinding operations. The grinding wheel's grain pattern is developed by kinematic simulation with special focus on the undeformed chip thickness. Current experimental investigations of dry grinding operations of hardened heat-treated steel are carried out with a material removal rate of Q′w=70mm3/mms. The measured grinding forces, workpiece temperatures, as well as workpiece surface quality and workpiece integrity are compared to wet grinding and a standard superabrasive electroplated grinding wheel as a reference process.
