【正文】 (3)圖紙表達(dá)正確,符合制圖規(guī)范;圖面整潔,布局合理,圖中線型和尺寸標(biāo)注符合要求,字體應(yīng)為工程字 ; (4)設(shè)計的有關(guān)技術(shù)經(jīng)濟(jì)指標(biāo)符合國家有關(guān)規(guī)范、標(biāo)準(zhǔn)和政策要求 ; 第 7 頁 (5)在設(shè)計過程中認(rèn)真、按時完成各階段的計算、設(shè)計和繪圖任務(wù) ; 設(shè)計條件 (1)數(shù)控實訓(xùn) 中心有相應(yīng)的專業(yè)機房和 CAD/CAM 軟件,具有仿真加工和實際加工的設(shè)備和能力 ; (2)可以借助圖書館的設(shè)計參考書和有關(guān)國家標(biāo)準(zhǔn) ; (3)數(shù)控實訓(xùn)中心有專業(yè)指導(dǎo)教師和操作指導(dǎo)技術(shù)人員 ; 畢業(yè)設(shè)計成果 (1)設(shè)計說明書電子稿和打印稿各一份; (2)圖紙 4 張以上(包括零件圖、加工工藝過程卡、加工刀路圖)。我們相信當(dāng)你認(rèn)識了CAXA 制造工程師以后, CAXA 制造工程師一定會走到你的身邊,成為你身邊的不可多得的造型能手,忠實可靠的編程高手,數(shù)控加工工藝的良師益友 。用戶按機床規(guī)定的格式進(jìn)行定制,即可方便地生成和特定機床相匹配的加工代碼。并可通過代碼較核,用圖形方法檢驗加工代碼的正確性。 用戶可以根據(jù)所要加工工件的形狀特點、不同的工藝要求和精度要求,靈活的選用系統(tǒng)中提供的各種加工方式和加工參數(shù)等,方便快速地生成所需要的刀具軌跡即刀具的切削路徑。由于分工越來越細(xì),企業(yè)之間的協(xié)作越來越頻繁,這種形式目前越來越普遍。 加工模型的建立是通過人機交互方式進(jìn)行的。這套系統(tǒng)集 CAD、 CAM 于一體,功能強大、易學(xué)易 用、工藝性好、代碼質(zhì)量高,現(xiàn)在已經(jīng)在全國上千家企業(yè)的使用,并受到好評,不但降低了投入成本,而且提高了經(jīng)濟(jì)效益。 90 年代以后國內(nèi)在 CAD/CAM 技術(shù)研究和軟件開發(fā)方面進(jìn)行了卓有成效的工作,尤其是在以 PC 機動性平臺的軟件系統(tǒng)。 隨著微電子技術(shù)和 CAD 技術(shù)的發(fā)展,自動編程系統(tǒng)也逐漸過渡到以圖形交互為基礎(chǔ)的與 CAD 集成的 CAD/CAM 系統(tǒng)為主的編程方法。在模具加工中,經(jīng)常遇到形 狀復(fù)雜的零件,其形狀用自由曲面來描述,采用手工編程方法基本上無法編制數(shù)控加工程序。數(shù)控加工的最大特征有二點:一是可以極大地提高精度,包括加工質(zhì)量精度及加工時間誤差精度;二是加工質(zhì)量的重復(fù)性,可以穩(wěn)定加工質(zhì)量,保持 加工零件質(zhì)量的一致。 關(guān)鍵詞 CAXA 制造工程師、 三維造型、數(shù)控機床、加工仿真 II ABSTRACT Threedimensional CAD / CAM design and manufacturing is the foundation of teaching, promote the use of threedimensional CAD / CAM design and manufacturing and other modern technology, taking a new road to industrialization, has bee the conscious action of design and manufacturing industry, and is a general trend, it is urgent. As the rate of the NC manufacturing equipment continue to improve, CNC machining technology in China are increasingly widely used in the mold industry, control or numerical control technology and the processing rate of the level of the NC has bee a symbol of whether the petitive . CNC machining technology is the key to puteraided design and manufacturing (CAD / CAM) system quality. How to prepare for NC machining program is CNC machining efficiency and quality of the key, the traditional manual programming methods plex, cumbersome and errorprone, difficult to check, it is difficult to give full play the function of CNC machine tools. In the mold, often experiencing plex shape parts, the shape used to descr ibe the free surface, using manual programming method is basically not prepared NC program. In recent years, due to the rapid development of puter technology, puters have greatly enhanced graphics capabilities, based on CAD / CAM technology for automated interactive graphics programming matures, this method is fast, high precision, intuitive, easy to use and easy to check. CAD / CAM technology in the industrial countries has been widely used. In recent years, more and more popular domestic applications, the manufacturing industry to bee an inevitable trend of technological progress. Keywords: CAXA Manufacturing Engineer 、 Threedimensional modeling、 Numerical Control Machine Tools、 Machining Simulation 第 1 頁 第 1 章 緒論 隨著制造設(shè)備的數(shù)控化率不斷提高,數(shù)控加工技術(shù)在我國得到日益廣泛的使用 ,在模具行業(yè),掌握數(shù)控技術(shù)與否及加工過程中的數(shù)控化率的高低已成為企業(yè)是否具有競爭力的象征。在模具加工中,經(jīng)常遇到形狀復(fù)雜的零件,其形狀用自由曲面來描述, 采用手工編程方法基本上無法編制數(shù)控加工程序。 0 基于 CAXA 軟件的轉(zhuǎn)接盤零件造型與仿真加工 The Connecting Plate Parts Moulding And Simulation Processing Based On CAXA Software 目 錄 摘 要 .......................................................................................................................I ABSTRACT..............................................................................................................
