Research on cam grinding process used on-line variable velocity based on fuzzy control theory

To get to constant force control is very important in non-circular parts manufacting. By gathering the singal from force transducer, adopt grinding force and its rate of change and C axis velocity to developing a fuzzy models. The fuzzy program codes is wrote in several PLC programs. By the on-line fuzzy caculating, the final C Axis velocity is got and wrote in manufacturing program. The cam grinding experiment results that the grinding forces stability used fuzzy on-line velocity is better than constant speed grinding.
