R&D and Application of Six-axis Motion Controller Based on Serial Communication

Aimed at motion control which is an important problem in numerical control system,the thesis introduces the concept and technique of the six-axis motion controller which is based on the PC serial port.Taking advantage of the PC serial port resources,the authors have researched and developed six-axis motion controller based on serial communication.The hardware structure of the motion controller is designed by the use of C51 MCU,and the software architecture and communication agreement are planned and described in detail.Then the motion controller is applied in welding machine and straightening machine,which has got good economic and social benefits.
