Research on the Auxiliary Working Hours of Locomotive Wheels Based on Feature and MOD

Because of the problem that how to formulate standard working hours quickly and accurately in the process of making time quota for enterprises at the present stage, we propose a concept which is a set of operating action and process feature. Considering the similarity of the attribute of process feature between the parts, and seeming the class of locomotive wheels as the object of research, we design a typical template of formulating standard process auxiliary processing time using MOD, this template faces process feature. In actual application, enterprises only have to modify the template slightly in view of the actual situation to meet the requirements.
