Notes:
Grinding wheel passivation is an inevitable phenomenon during grinding process. It hasimportant guiding significance for the formulation of grinding technique to unveil the passivation ruleand generation mechanism. Taking grinding efficiency as evaluation indicator, the passivation curveof grinding wheel during full passivation period under the constant-force grinding condition isestablished through experiments in this dissertation, which is divided into three stages according topassivation speeds and passivation patters, i.e. early passivation stage, stable passivation stage andsharp passivation stage. Of which, the passivation speed is the slowest but with the highest grindingefficiency in early passivation stage. The change of passivation curve with the time is a process fromconcave to convex, which is totally different from the wearing process of grinding wheel in this stage.With combination of experiment conditions and wearing characteristics of grinding wheel, thepassivation rule and its generation reasons are discussed deeply. Furthermore the exponentialfunction y = abx is adopted to make fitting for passivation curve based on the scatter plot of stablepassivation stage and regression equation is derived through the fitting result of origin thus to testifythe correctness of the inference
