Abstract:
In the present work, the process of grinding is represented through the dynamic interactions of the workpiece with the abrasive grits of the grinding wheel. A mathematical model (grinding dynamic model with wheel and workpiece-GDMWW) based on the resulting instantaneous depth of cut is then developed. The proposed model utilizes the governing equations of motions for both the wheel and the workpiece in a multi-grit grinding process. The cutting action is represented through the interactions of the wheel and the workpiece motions on each other. The parameters for the proposed multi-body dynamic model can be easily identified from simple experimentations (e.g., modal tests). Using the identified parameters, simulations with the proposed dynamic model are carried out for stable grinding processes. These simulation results are first verified against experimental observations obtained from grinding of soda-lime glass. The dynamic model is then utilized to investigate the regenerative effects, e.g., surface regeneration, mode coupling and velocity dependence. The effects of such effects on stability characteristics of ceramic grinding processes are investigated and possible remedies are suggested.
