The Development of CNC System Based on Hardware/Software Codesign

WANG Li-song1,2,LI Tie-cai1,ZHANG Jing2,WU Hong-jian2(1.Shenzhen Tech-Innovation International,Shenzhen 510000,China;2.South China University of Technology,Guangzhou 510640,China)  
An open CNC system based on hardware/software codesign is discussed in this paper.The three-layer structure mathematical model is built as the foundation of the system.By analyzing the system constraint condition and optimizing target,the system hardware and software functions are divided.This paper also presents the method of creating hardware abstraction layer and detailed design of the software and hardware function.The machining experiments with this system in Guangzhou Machine Tool Factory shows the roundness error of machining semi-sphere is below 12μm,which satisfied the precision requirement of the factory.
