Research of Grinding Wheel Wear Modeling Based on Hypothesis Test Principle

Grinding wheel wear has an obvious stage character, only in the end of wear stage, the workpiece surface quality will decrease significantly, in order to avoid such situation, need to find the critical point of grinding wheel wear in time. Based on the production field data, combined with the application of hypothesis test method, a new method to infer grinding wheel wear state was established in the article, the degree of grinding wheel wear can be quantificationally analyzed. Via practical production testing, is checked that the new method is effective.
