Research on Temperature Field of Nano-Composite Ceramics by Multi-Ultrasonic Grinding

Abstract:

In processing of structure ceramics materials with diamond grinding wheel, grinding heat is one of vital factors influencing workpiece surface quality. Grinding parameters have important influences on workpiece surface temperature distribution. Contrast experiments on grinding temperature field of ZrO2 in common and ultrasonic grinding were carried out in the paper by manual thermocouple method. The relationship between grinding parameters and temperature were researched theoretically and experimentally. The results show that the farther the distance from grinding surface, the smaller the peak value of temperature is. With the increases of grinding depth, grinding speed and feedrate, the surface temperature will heightens accordingly. It was proved that grinding depth is the most vital factor influencing grinding temperature field through orthogonal experiments. Furthermore, comparing with high surface layer temperature which often results in grinding burn in traditional grinding, ultrasonic grinding can reduce grinding temperature effectively.
