Numerical Estimations of the Deflection-Reducing Process in Belt Grinding

This research aims at developing a method of numerical calculations and clarifying the characteristics of a roundness error reducing process in rubber contact wheel type belt grinding. Cylindrical plunge belt grinding was carried out on the eccentric workpieces in place of workpieces having a roundness error. Judging from the results obtained by comparing the eccentric workpieces with the normal round workpieces, there was little difference in the forming process, regardless of the infeed conditions. Therefore, a model of the deflectionreducing process of the eccentric workpiece was estimated. Using this model, a deflectionreducing process by numerical calculations was proposed and it was confirmed that its results were in close agreement with the experimental results. So, the effects of the grinding conditions on the deflection-reducing process were calculated. As a result, the characteristics and problems were clearly recognized for the grinding of eccentric workpieces.
