【正文】 編程 、刀具路徑摸擬及真實(shí)感摸擬等多種功能于一身。從目前世界上數(shù)控技術(shù)發(fā)展的趨勢(shì)來看，其主要研究熱點(diǎn)有以下幾個(gè)方面。當(dāng)今世界各國(guó)制造業(yè)廣泛采用數(shù)控技術(shù)，以提高制造能力和水平，提高對(duì)動(dòng)態(tài)多變市場(chǎng)的適應(yīng)能力和競(jìng)爭(zhēng)能力。特別是近幾年，我國(guó)加大了對(duì)數(shù)控技術(shù)的研發(fā)力度，在諸多方面取得突破性進(jìn)展，如可以供應(yīng)集成 化和網(wǎng)絡(luò)化的制造裝備；五軸聯(lián)動(dòng)技術(shù)逐步成熟；進(jìn)入了世界高速、高精度、精密數(shù)控機(jī)床的生產(chǎn)國(guó)的行列等等，并且擁有自主知識(shí)產(chǎn)權(quán)。 數(shù)控技術(shù)的廣泛使用為 制造業(yè) 提供了全新的生產(chǎn)制造模式，數(shù)控技術(shù)是利用數(shù)字信息對(duì) 機(jī)械 和工作的活動(dòng)進(jìn)行控制的一項(xiàng)技術(shù)。 所以 我國(guó)的 數(shù)控技術(shù)人才一方面要具有數(shù)控基礎(chǔ)理論知識(shí) ,另一方面還要具有解決實(shí)際問題 的能力。 零件幾何模型的構(gòu)建 ........................................................................................ 22 機(jī)床加工注意事項(xiàng) ................................................................. 錯(cuò)誤 !未定義書簽。 繪制上層實(shí)體 ....................................................................................................... 11 第 2 章 零件的工藝分析 .............................................................. 錯(cuò)誤 !未定義書簽。 繪制中間層外輪廓 ................................................................. 錯(cuò)誤 !未定義書簽。 關(guān)鍵詞 :數(shù)控加工 ， 尺寸 ， 加工工序 ABSTRACT Numerical control technology and CNC machine tools in today39。 數(shù)控技術(shù)及數(shù)控機(jī)床的廣泛應(yīng)用，給機(jī)械制造業(yè)的產(chǎn)業(yè)結(jié)構(gòu)、產(chǎn)品種類和檔次以及生產(chǎn)方式 都 帶來了革命性的變化。 本次畢業(yè)設(shè)計(jì)是端蓋零件基于 MacterCAM 的的建模與編程加工， 該零件的尺寸精度、形狀精度以及位置精度的要求都很高，因此在安排工藝過程時(shí)，就需要把各主要表面的粗精加工工序分開。s machinebuilding industry an important position and great benefits, shows its strategic role in the modernization of national industries, and has bee a traditional machinery manufacturing industry transformation and automation, flexibility and integration of important means of production and logo. The wide application of numerical control technology and CNC machine tools, machinery manufacturing industry structure, product categories and grades, as well as changes in production are revolutionized. The graduation is the end cover parts based on MacterCAM model and the programming process, the part accuracy of size, shape and location accuracy requirements are very high, so when scheduling process, you need to separate the main surface rough and finish machining operations. Gradually reduce allowances, cutting forces and the role of internal stress and deformation of the amendment process in order to achieve the technical requirements of the parts. CNC machining is introduced in this paper features, machining technology and NC programming procedure design using AutoCAD to plete part of the plane in the view, then use the MasterCAM software design of three dimensional modeling and path parts, and finally with MasterCAM parts machining simulation.
