Determining the Conditions for Achieving the Plastic Regime of Diamond Grinding of Ceramics from the Standpoint of Estimating Energy Costs of Processing

We studied the plastic mode of processing brittle materials, the effect of the change in the working surface of the diamond wheel during processing, and ways to achieve such a mode. To assess adequately the energy intensity of processing with diamond wheels, we proposed to calculate the specific energy density of grinding, considering the volume of material spent during the processing of the wheel working layer. We derived an equation for calculating the specific energy density during the diamond grinding of ceramics. The plastic regime occurs precisely when the specific energy density of grinding becomes close to the specific heat of melting of ceramic materials.
