Intelligent Control System of CNC Mill Machineing Based on the Feed-Driven Linear Motor

摘要

Taking the feed-driven linear motor mechanism as the control object, the SEMODRTVE 611D as the control system, establish mathematical model of the servo system. The relation between feed-axis current and cutting force is presented, the current and feed-rate are separately selected as feedback and output. Around the aim of the feed-axis constant current control, choose the fuzzy control as the control method of the linear feed-driven machining process. The simulation results indicate that the intelligent control system has fast response time and good performance of anti-jamming, also the experimental results show the efficiency of milling can be unproved and tool be highly protected.
