在開放式數(shù)控系統(tǒng)的開發(fā)中，針對國內(nèi)外眾多的數(shù)控系統(tǒng)硬軟件平臺，并利用層次分析法多準(zhǔn)則決策方法的定性、定量結(jié)合的思路，建立層次結(jié)構(gòu)數(shù)學(xué)模型，成功地篩選出了滿足要求的理想的開放CNC數(shù)控系統(tǒng)。該系統(tǒng)是用PMAC多軸運動控制卡構(gòu)造的PMAC-NC數(shù)控系統(tǒng)，能滿足工程技術(shù)的要求和教學(xué)的需要。

In development of open numerical control systems，there are numerous hardware and software in the market of the home and abroad. This paper utilizes the AHP method in the architecture mathematical modeling, the open CNC (Computer Numerical Control) system is successfully selected to meet ideal demand. This system is a PMAC-NC (Programmable Multi-axis Controller Numerical Control) system, in which numerical control machine tools is controlled by PMAC multi-axis motion controller. The system can meet the require of engineering and instruction.
