In grinding, there are many perturbations to the spindle that degrade the quality of the workpiece surface being ground. Imbalance of the grinding wheel and runout of the wheel are two examples of such perturbations. These disturbances manifest themselves as varying system forces or varying system displacements. The dynamics describing the combination of machinery and material removal process then determine how these perturbations affect the process, for example, the grinding force or grinding depth of cut. The system output is given in terms of the degradation in quality of the workpiece surface. It is only in the context of the whole system that the effect of poor wheel balance and poor wheel truing on workpiece quality can be assessed.
