This research will integrate and implement a high-speed network serial bus interface between CNC machine tools and servo motor through the CNC controller. Based on the advantage of high-speed information transportation through the network technology, parameter identification, auto-tuning, nonlinear friction compensation, and machine resonance detection and suppression can be achieved through the designed intelligent interface. This project will complete the integration and implementation of the network serial bus interface between CNC machine tools and servo motors in three years. Main research topics will develop the following techniques: 1. CNC high-speed network serial bus between CNC machine tools and servo motors, 2. CNC servo motor control, auto-tuning and identification techniques, 3. Integration of servo motor and CNC machine tool through the intelligent interface We will implement high-speed network serial bus based on EtherCAT network. We will also overcome the command transportation delay in CANopen-based industrial network. Combining with CNC servo motor driver control, tuning and identification technique, the development platform of the network control systems for the CNC servo control will be completed in this project. This research result would be helpful for CNC machine industry in Taiwan.
