Using Fuzzy Control for Feed Rate Scheduling of Computer Numerical Control Machine Tools

In industrial processing, workpiece quality and processing time have recently become important issues. To improve the machining accuracy reduce cutting time, feed rate will a significant impact. Therefore, how to plan dynamic is very important. this study, fuzzy control system for scheduling based on curvature variation proposed. The proposed implemented in actual cutting, verify data an optical three-dimensional scanner used measure trajectory of workpiece. Experimental results prove that increases by 41.8% under same time; moreover, it decreases 50.8% approximately accuracy.
