Modeling and Simulation of Single Abrasive-Grain Cutting Process in Creep Feed Grinding

Abstract

Single abrasive-grain cutting is the key research point in grinding process. Because of the narrow space and quick velocity, modeling and simulation method is an approach way to study the single grain cutting. This paper studied the distribution of flow stress and plastic strain, the temperature field near cutting grain. Then experiment was conducted to measure the cutting forces in single grain cutting test. The validation shows good correctness and accuracy of FEA model. Then orthogonal simulation test was carried out to research the influence factors for the grinding forces and temperature distribution. It is found that creep feed grinding has a large grinding forces than high speed grinding in the grain scales. But the maximum temperature value is affected both by depth and speed distinctly.
