Simulation of the process of creep-feed diamond grinding of hardmetals

To determine the efficiency of diamond grinding of hardmetals, which is characterized by specific metal removal rate, it is necessary to determine the volume of chip removed by the one grain taking into consideration it's curvilinear. A scheme for calculating the chip area in the longitudinal cross section with taking into consideration of its curvilinear was developed. According to the obtained equations, the volume of chips removed was determined, which provide a way to calculate the maximum force acting on the grain with higher accuracy. Comparative analysis of the motion trajectory of the grain obtained by the simulation in SolidWorks and by the calculating using the equations showed that the error between the coordinates no more than 2%.
