On Modelling of Stochastic Processes of Abrasive Wear and Durability of Grinding Wheel

The aim of the paper is to present modelling of abrasive wear and grinding wheel durability by means of probabilistic description of abrasion and crush dressing of grinding wheels. Relations describing distributions of active grain age and its change during of grinding are determined. A practical application of the models proposed in the paper, using empirical data, makes it possible to determine other quantities which are very difficult to estimate in an experimental way.
