Numerical Simulation of Single Grit Cutting

Abstract:

Grinding process can be considered as micro-cutting processes with a lot of irregular abrasive grits on the surface of grinding wheel. The study of the grit-workpiece interaction through single grit cutting is an important contribution to describe the material removal processes in the grinding process. In this study, single grit cutting processes with different process parameters (depth of cut, cutting speed) were modeled by FEM software AdvantEdge. The critical depth of cut from plowing t cutting was investigated. The simulated tangential and radial cutting forces increase sharply due to the pile-up of workpiece material in the front of single grit when the depth of cut reached to some value. And the increase extent of cutting forces at low cutting speed is larger than that at high cutting speed due to the thermal softening of workpiece material. The simulated highest cutting temperature increase first, and then decrease, finally increase again with the increase of depth of cut. And the peak value of simulated highest cutting temperature occurs near the critical depth of cut. The simulated material removal rate increases with the increase of cutting speed and depth of cut.
