d development of puter technology, puter threedimensionalmodeling technology especially the reverse engineering technology has been widely applied in industry. In order to solve the problem of measuring the alarmhousing problems, in this study the modeling method of reverse engineering the shell shape of the alarm clock, and elaborates on the concept, method of reverse engineering. Gets the data cloud shell surface of the alarm clock by noncontact measurement scanner, and processing the measured data by using the Imageware software, and based on curved surface design realize surface reconstruction alarm clock shell, 3D model is generated alarm clock with the traditional topdown design method, this method improves the work efficiency, shorten the development cycle of new products. Plastic die mold industry is an important ponent, but also reflects the level of a country39。 point cloud。 modeling 目 錄 引言 6 基于 Imageware 點云處理 39 使用性能 40 成型性能 41 鬧鐘前蓋原料的特性和工藝參數(shù) 41 ABS 塑料主要的性能指標(biāo) 42 鬧鐘前蓋原料的特性和工藝參數(shù) 42 選擇注射機(jī) 42 最大注射壓力的校核 44 型腔的徑向尺寸 44 型芯的計算 44 主流道設(shè)計 45 分流道設(shè)計 46 分流道的長度 46 澆口選擇 47 分型面的選擇 47 排氣糟的設(shè)計 48 7 合模導(dǎo)向機(jī)構(gòu)的設(shè)計 49 9 溫度調(diào)節(jié)系統(tǒng)的設(shè)計 51 模具加熱系統(tǒng)的設(shè)計 51 模具的裝配順序 52 11 結(jié)論 53 謝辭 55 鬧鐘逆向造型畢 業(yè)設(shè)計資料 詳詢 946538029 引言 逆向工程 (Reverse Engineering)是根據(jù)現(xiàn)有實物模型的測量數(shù)據(jù)演繹出零件的設(shè)計概念和 CAD 模型,其目的就是消化吸收并改進(jìn)國內(nèi)外先進(jìn)技術(shù),快速趕上或超過世界先進(jìn)生產(chǎn)技術(shù)水平、贏得市場競爭.作為近年來迅速發(fā)展的快速設(shè)計制造技術(shù)的重要分支,可大大縮短產(chǎn)品制造周期,因而在制造領(lǐng)域得到了廣泛的應(yīng)用。用模具制造零件以其效率高,產(chǎn)品質(zhì)量好,材料消耗低,生產(chǎn)成本低而廣泛應(yīng)用于制造。在模具制造方面,掌握一般機(jī)械加工的知識,金屬材料的選擇和熱處理,了解模具結(jié)構(gòu)的特點,根據(jù)不同情況選用模具加工新工藝。最終得到方便 進(jìn)行操作的點云數(shù)據(jù);將處理好的點云數(shù)據(jù)拿到 中進(jìn)行重新建模以及創(chuàng)新設(shè)計,最后得
