Forecasting the Reliability of Automated Grinding Systems on the Basis of Young's Modulus of Grinding Wheels

Abstract

The paper presents the model of procedure and the results of forecasting the operational reliability of conventional grinding wheels applied to automated production systems. The forecasting was issued on the basis of Young’s modulus of these tools obtained from preoperational acceptance inspection. The model was verified during the process of internal grinding of bearing rings. Investigations were applied to 100 ceramic grinding wheels with the same characteristics. As a criterion for operational reliability were assumed: the grinding wheels radial wear Δrs, the maximum spindle power demand Pc and the arithmetical mean deviation of the roughness profile Ra. It was demonstrated that the operational reliability of tools under investigations was strictly interrelated the modulus E. Therefore; it can be used as a prognostic criterion for reliability of the system including these tools.
