Grinding with controlled kinematics and chip removal

This paper presents the results of simulation and experiments conducted around the application of controlled kinematics and chip removal conditions during infeed grinding cycles. The method consists on the application of continuous variation strategies of the three main speed variables that govern the removal mechanism and therefore the tribo-thermo-mechanical behavior of the process: grinding wheel speed, workpiece speed and feed rate. With the help of a time-domain simulation, the influence of this method on the process behavior is analyzed demonstrating numerous potential applications of the variable cycles by comparing with conventional ones. Tests have been performed to validate this technology and demonstrate the improvements of the variable cycles.
