Study of local temperatures at the plastically deforming grains during grinding with ultrasonic oscillations imposing

The physical and mathematical models to calculate the local temperatures at the plastically deforming grains of grinding wheel are developed. Represented models take into account changes of kinematic of material dispersing by abrasive grains and the mechanical properties of the workpiece material while applying ultrasonic oscillations. Also developed a method and software for the calculation of the temperature field and technique for the temperatures numerical simulation. The simulation results showed that the using of ultrasonic oscillations lead to reduce the local temperatures at 24-30%.
