Predictive model for cutting forces and specific cutting energy in ultrasonic-assisted grinding process: a mechanistic approach.

The present research work focuses on developing a mechanistic model for the specific grinding energy in UAG process. Based on the developed model, the effect of cutting parameters has been studied. The cutting force plays a significant role in appraising the performance of machining process. The effect of various forces such as tangential, normal, and vibrational forces has been considered during UAG machining process, and a model has been proposed based on these forces. In the UAG process, the grinding wheel is rotated, and the workpiece is simultaneously vibrated with small amplitude and high frequency. The experimental studies revealed that ultrasonic vibration in grinding operations enhanced the overall performance by reducing cutting forces and improving surface integrity, resulting in less energy consumption. The developed model included various parameter effects such as frequency, amplitude, speed of the wheel, table speed, depth of cut, and width of cut. This mathematical model showed favorable outcomes validated with the data obtained from an experimental setup. This model can be utilized for future research in the direction of effective force and specific grinding energy and can contribute towards realizing sustainable grinding studies.
