【摘要】：數(shù)控系統(tǒng)是數(shù)控機床技術的核心。傳統(tǒng)的數(shù)控系統(tǒng)是一個封閉體系的結構系統(tǒng),其通用性差、難移植性且無法實現(xiàn)網(wǎng)絡化管理；而基于通用PC數(shù)控技術也存在系統(tǒng)資源無法充分利用、硬件結構無法很好地滿足實時性要求、沒有現(xiàn)成的數(shù)控系統(tǒng)硬件模塊等問題。 針對上述問題,提出對基于WindowsCE的嵌入式系統(tǒng)關鍵技術進行研究。利用其集成度高、體積小、易擴展等特點,開發(fā)一款具有自主知識產權的嵌入式數(shù)控系統(tǒng),以滿足實時性和通用性要求。并在系統(tǒng)中加入錯誤檢查與實時仿真功能,使系統(tǒng)操作方便和具有可視化。論文主要研究內容包括： 1.對嵌入式數(shù)控系統(tǒng)的功能需求進行分析,確定其系統(tǒng)的總體架構。為滿足數(shù)控系統(tǒng)多任務、強實時的要求,對數(shù)控系統(tǒng)的硬件平臺進行設計,并對上下位控制器進行選型。針對其需實現(xiàn)的各項功能設計專門的數(shù)控系統(tǒng)軟件系統(tǒng),并完成了對應軟件系統(tǒng)的開發(fā)。 2.設計譯碼模塊和刀具補償模塊。采用編譯的方式實現(xiàn)對數(shù)控程序進行譯碼,調用譯碼模塊中的錯誤檢查模塊對讀入的數(shù)控程序進行分離和詞法、語法的檢查,并針對復雜的數(shù)控程序中調用子程序的情況設計相應的子程序錯誤與譯碼模塊,以擴展軟件的處理能力；刀補模塊使用平面C功能刀補算法對實際加工中所遇到的輪廓偏移進行計算,簡化加工程序的編寫。 3.通過實例驗證開發(fā)的數(shù)控系統(tǒng)譯碼與刀補模塊。 論文結尾部分對本數(shù)控系統(tǒng)存在的問題進行總結,并提出其需改進與完善的工作。
[Abstract]:Numerical control system is the core of NC machine tool technology. The traditional CNC system is a closed structure system, its universality is poor, it is difficult to transplant and can not realize network management. Based on the general PC numerical control technology, the system resources can not be fully utilized, the hardware structure can not meet the real-time requirements, there are no ready-made CNC system hardware modules and so on. Aiming at the above problems, this paper puts forward the research on the key technology of embedded system based on WindowsCE. Based on its characteristics of high integration, small volume and easy to expand, an embedded NC system with independent intellectual property rights is developed. In order to meet the requirements of real-time and generality, error checking and real-time simulation are added to the system, which makes the system easy to operate and visual. The main contents of this thesis are as follows:. 1. The functional requirements of embedded CNC system are analyzed, and the overall architecture of the system is determined. In order to meet the multi-task and strong real-time requirements of CNC system, the hardware platform of CNC system is designed. The software system of numerical control system is designed according to its functions, and the corresponding software system is developed. 2. The decoding module and tool compensation module are designed. The NC program is decoded by compiling method, the error checking module in the decoding module is called to separate the NC program read in and the lexical and grammatical checking is carried out. The subroutine error and decoding module are designed to expand the processing ability of the software. The cutter compensation module uses plane C function cutter compensation algorithm to calculate the contour offset encountered in the actual machining, which simplifies the programming of the machining program. 3. The decoding and cutter compensation module of NC system is verified by an example. At the end of the paper, the problems of the CNC system are summarized, and the work to be improved is put forward.
