Description
Summary:Grinding is used to reduce form error and improve the surface quality of workpiece in metal cutting. To investigate the grinding process of cast iron, a series of grinding tests and simulation of cast iron were carried out. At the same time, the finite element method was used to establish a finite element model to simulate the grinding process of cast iron. In the model, the dynamic effects, thermo-mechanical coupling, Johnson–Cook constitutive model, material damage model, and contact model were taken into account. Then, the grinding process of cast iron was simulated using the established finite element model in the ABAQUS software. Material remove, residual stress, grinding force, and cutting temperature were achieved through the simulation. In addition, the effect of the main grinding parameters (depth of grinding and spindle speed) on residual stress, grinding force, and surface quality in the grinding of cast iron was investigated.
