- Abstract
The article focuses on the analysis of thermomechanical modeling of cutting by single abrasive micro-size grain while the process of grinding. In this research, applying the Johnson-Cook" material model, which relates the intensity of stress with strain rate, temperature and the accumulated plastic strain. Using arbitrary Lagrangian-Eulerian (ALE) approach makes it possible avoid the distortion of finite elements in the simulation of chip-formation under large deformations. The simulation allows predicting cutting force for processing workpiece of titanium alloy Ti6Al4V by single grain grinding.
