Study of Grinding Force for Internal Cylinder of Ultrasonic ELID Composite Grinding

Abstract:

In order to reveal the theoretical nature of ultrasonic ELID composite grinding which is an efficient grinding technology, this paper theoretically analyzes a single grains motion characteristics in the process of internal cylindrical grinding under axial vibration and established a single grits kinematic equation. Then the grits trajectory is draw by matlab, and the contact length of the grinding wheel and the workpiece is achieved. At the same time the electrolysis parameters are introduced into the dynamic number of effective grits with analysis its electrochemical action. Thereby a force model for the ultrasonic ELID composite internal cylindrical grinding is established. Through analysis the model it is easy to find the force is fluctuated periodically with electrical current changing.
