【正文】 造大國(guó)，我國(guó)制造工業(yè)飛速發(fā)展的同時(shí)，與世界制造先進(jìn)水平的差距在不斷縮小，而作為現(xiàn)代制造技術(shù)的靈魂及核心，數(shù)控加工技術(shù)也得到了廣泛的應(yīng)用，各類CAD/CAM 軟件的應(yīng)用日趨普及，特別是在數(shù)控三維曲面加工中手工編程幾乎已無(wú)用武之地然而強(qiáng)大的思維定式和使用習(xí)慣，使得編程人員不論程序大小、加工難易都習(xí)慣使用 CAD/CAM 軟件來(lái)編程，手工編程似乎被遺忘了，而在學(xué)習(xí)手工編程時(shí)只是簡(jiǎn)單地學(xué)習(xí)基本的編程指令。但有時(shí)這些指令滿足不了用戶的需求，系統(tǒng)因此提供了用戶宏程序平臺(tái)，用戶可以對(duì)數(shù)控系統(tǒng)進(jìn)行一定的功能擴(kuò)展，即在數(shù)控系統(tǒng)宏程序功能的平臺(tái)上進(jìn)行開(kāi)發(fā)，其開(kāi)發(fā)出來(lái)的程序就是宏程序。在相似的工序中，修改相關(guān)參數(shù)即可實(shí)現(xiàn)宏程序多次使用。用戶宏程序 B 可以使用數(shù)學(xué)函數(shù)進(jìn)行參數(shù)編程，實(shí)現(xiàn)編程的參數(shù)化，無(wú)需進(jìn)行大量繁瑣的計(jì)算。同時(shí)，采用 FANUC 數(shù)控系統(tǒng)宏程序?qū)?shù)控銑床上典型工序模型凸臺(tái)、斜面、以及包含各類二次圓錐曲線的曲面等進(jìn)行編程及仿真加工，有利于實(shí)現(xiàn)程序模塊化，并達(dá)到較高的效率。論文首先從數(shù)控宏指令的特點(diǎn)、加工零件的范圍著手，對(duì)用戶宏程序 B 的數(shù)學(xué)應(yīng)用基礎(chǔ)、變量賦值、運(yùn)算、循環(huán)、轉(zhuǎn)移等功能，及非模態(tài)指令G6G66/G67，G 和 M 代碼指令的調(diào)用進(jìn)行說(shuō)明。畢 業(yè) 論 文論文題目 基于 FANUC 數(shù)控系統(tǒng)宏程序的典型零件加工 系 別 電子信息工程系 專 業(yè) 機(jī)械設(shè)計(jì)制造及其自動(dòng)化 班 級(jí) 學(xué) 號(hào) 學(xué)生姓名 指導(dǎo)教師（簽名） 完成時(shí)間 2022 年 3 月摘要宏程序是對(duì)數(shù)控系統(tǒng)的一種功能擴(kuò)展，即在其功能平臺(tái)上進(jìn)行開(kāi)發(fā)，開(kāi)發(fā)出來(lái)的程序稱之為宏程序。宏程序是數(shù)控系統(tǒng)中一種具有計(jì)算能力和決策能力的數(shù)控程序，也可稱之為參數(shù)化編程。然后，基于 FANUC 數(shù)控系統(tǒng)的宏程序，解決自動(dòng)編程中無(wú)法進(jìn)行參數(shù)化編程的難題，編制出可在數(shù)控車床上加工的橢圓 O800雙曲線 O800拋物線 O8003 三種二次曲線的走刀指令，實(shí)現(xiàn)非圓曲線的二次開(kāi)發(fā)。最后，應(yīng)用宏程序?qū)E圓手柄、平行四邊形框點(diǎn)式孔群兩種典型零件進(jìn)行編程和仿真加工，驗(yàn)證宏程序加工的特點(diǎn)。其次，它還具有通用性，參數(shù)易于修改、程序可循環(huán)使用等特點(diǎn)。關(guān)鍵詞： 宏程序 參數(shù)化 自動(dòng)編程IBased On FANUC Macro Program For The Typical CNC MachiningAbstractMacroprogram is a kind of function expansion to the CNC system, namely, we can develop on its function platform ,we call the program what is developed out as the macroprogram. Macroprogram is a kind of CNC program which keeps the calculating power and decision power, also called nc parametric programming. Firstly, the essay begins with the feature of CNC macro instrucion and the scope of processing pieces, explaining the function of mathematical application basis user macroprogram B, variable assignment, operation circle, shift and transferring the nonmodal order G65,G66\G67,the code order of G and M. Secondly, it bases on the macroprogram of FANUC CNC system, solving the problem of unable parameterization programming during automatic programming, piling out the knife order of the oval 08001, hyperbolic cure 08002, parabolic curve 08003 three kinds quadratic curve which can work on the NCN lathe, and realized secondary development of the noncircular curve. At the same time, we can use the FANUC CNC system macroprogram to pile and process the typical production model boss, obliquity, and the curved surface of all kinds off secondary cone curve on the CNC lathe. It is beneficial to realize the program modeling and achieve higher efficiency. Finally, we can apply macroprogram to pile and process on the two typical parts of oval rein and orifice parallelogram. We also can check the working feature of marcoprogram.We use the mathematical function to make a parameteic program to the user marcoprogram and realize the parameterization programming. It is unnecessary to carry on so hittygritty calculation.Secondly, it also has the feature of generality, the parameter is easy to be revised and program can cyclic utilization. On the same production, we can realize macroprogram multiple use when we revise the related parameter.Key word： macro program Parametric Automatic programmingII目錄第一章 緒論 .....................................................................................................................1 宏程序的定義 ..........................................................................................................1 宏程序的發(fā)展現(xiàn)狀 .................................................................................................1 宏程序的編程特點(diǎn) ..................................................................................................2 適用宏程序加工的內(nèi)容 ..........................................................................................3 宏程序與普通編程的比較 ......................................................................................4第二章 宏程序數(shù)學(xué)基礎(chǔ)應(yīng)用 ........................................................................................5第三章 用戶宏程序轉(zhuǎn)移和循環(huán) ....................................................................................9 變量 ..........................................................................................................................9 算術(shù)與邏輯運(yùn)算 ....................................................................................................11 轉(zhuǎn)移與循環(huán) ...........................................................................................................13第四章 宏程序功能 .......................................................................................................17 用戶宏程序 A .......................................................................................................17 用戶宏指令 B........................................................................................................18 宏程序語(yǔ)句的處理以及使用限制 .......................................................................23第五章 宏程序在數(shù)控車/銑床的應(yīng)用 ..........................................................................24 數(shù)控車床非圓二次曲線的走刀宏程序 ...............................................................24 數(shù)控銑床單一工序宏程序模塊化編程 ...............................................................25 小結(jié) .......................................................................................................................39第六章 FANUC 車床宏程序的典型零件加工實(shí)例一 ..................................................40 加工方案選擇及確定 ............................................................................................40 橢圓手柄工藝分析 ................................................................................................41 橢圓手柄宏程序編程加工 ....................................................................................44 MASTERCAM 軟件自動(dòng)編程 ................................................................................48 宏程序加工的實(shí)體模型分析 ................................................................................52第七章 FANU
