    摘要:

    為實(shí)現(xiàn)開放式數(shù)控系統(tǒng)的可移植性、可擴(kuò)展性及可互換性等特性，引進(jìn)軟件工程學(xué)思想，提出了基于組件技術(shù)的開放式數(shù)控系統(tǒng)體系結(jié)構(gòu)。闡述了組件技術(shù)的原理及實(shí)現(xiàn)技術(shù)。軟件設(shè)計(jì)采用雙層面設(shè)計(jì)方式，利用CORBA組件模型并使用星式通訊機(jī)制，建立各組件之間的組成及通訊方式。以自主研發(fā)的混聯(lián)式虛擬軸研拋機(jī)床為平臺(tái)，進(jìn)行了三維曲線加工軌跡仿真實(shí)驗(yàn)，表明基于該體系結(jié)構(gòu)的數(shù)控系統(tǒng)具有良好的開放性及動(dòng)態(tài)性能。

    Abstract:

    A kind of architecture of open CNC system based on component technology was introduced by importing the theory of software engineering for realizing its characteristics of portability, expansibility and interchangeability and etc. The theory and realizing technology of component technology have been introduced. The software design of the system adopted a double-level by using the model of CORBA components. A star communication mechanism has been used to build the organization among the components and the method of communication. A simulation experiment of 3-D curve machining location on the self-developing hybrid virtual axis polishing machine tool was produced to prove that the CNC system based on this architecture has good openness and dynamic performance.
