Study On Open Component Architecture CNC System Based On CCM Technology

Because of drastic market competition confronted by manufacturing corporations ,CNC system is developing to high-precision, high-speed, high-efficiency , intellectualized and distributed network ability in 21st Century. However, traditional NC system have a lot of disadvantages, for examples, the close structure, simplex functions,a long research period and high costs etc. which have confined manufacturing developments. With the fast development of IT technologies, many research organizations brought forward one open architecture CNC system and did lots of research on this field in succession. Based on detailed analysis of these research actualities, one Open Component Architecture&RTCORBA CNC system (OCARCNC) is presented.Taking advantages of OSACA,OROCOS and OMAC projects and combining with principles of component technologies, this paper analyzes one common CNC system's functions and their future development,then advances one two-layer components model for OCARCNC.This paper accurately defines each component's functions and definitely points out intercommunication among components. In order to make this system scalable and secure, to assure its architecture good enough to promote codes reusable, this paper makes models for each component with UML modeling tool - Rational Rose. All these models will undoubtedly promote continuable development of open architecture CNC system greatly.As the communication soft bus among components, CORBA and RTCORBA inter-ORBs' communication abilities are emphatically...
