Completes this design to obtain from the following several steps: pair gives the detail drawing carries on the analysis. This ponents are the symmetric figure, the size request are not high, but has the fillet, the surface and the conic section plex structure, requests high to the processing procedure. According to the detail drawing, the reasonable idea processing sequence, and the digitized modelling, draws the ponents with the UG software the block diagram, and chooses the semifinished materials material and the size. ponents carry on the technological analysis. The processing ponents are the symmetrical graph, a ponents39。s application, is now getting more and more important in society39。 關(guān)鍵詞 : 零件的分析 裝夾 工藝 編程 宏程序 1 Abstract Because the numerical control processing its high flexibility, the high accuracy, highly automated and the high efficiency39。零件加工的是內(nèi)部結(jié)構(gòu)，所以由上之下，由中間到四周進(jìn)行加工。 手動編寫出零件的加工程序，零件的程序中應(yīng)用到了 倒圓角的宏程序，球面的宏程序，二次曲線的宏程序。根據(jù)刀具和 零件的要求算出切削用量，制定 工藝卡片。 加工零件 選擇合理道具， 粗銑毛坯量大，用面銑刀進(jìn)行加工，其余的用φ 6 的立銑刀加工。 非加工的邊緣四周區(qū)域是正方形 ，所以方便裝夾，對 夾 具的要求不高。 工藝 性分析。 本零件是對稱圖形，尺寸要求不高， 但是有圓角、曲面和二次曲線 較復(fù)雜的結(jié)構(gòu)，對加工的程序要求高。 本次畢業(yè)設(shè)計(jì)是關(guān)于 某個 零件的 加工工藝與 程序 進(jìn)行分析與 編制， 在本次設(shè)計(jì) 中 ,通過對零件的圖形分析 ,材料分析 ,選好了加工毛坯 尺寸 ,另外還對加工的工序 .工藝進(jìn)行分析 ,從而手工將加工零件的全部工藝過程、工藝參數(shù)、位移數(shù)據(jù)等以規(guī)定的代碼、程序格式寫出 ,編制出了適合所選銑床的程序。摘 要 數(shù)控加工因?yàn)槠?高柔性、 高精度、高度自動化與高效率的特點(diǎn)，在機(jī)械制造業(yè)中的應(yīng)用越來越廣泛，在當(dāng)今社會的位置 越來越重要 。 本次設(shè)計(jì)我 使用手動編程。 完成這次設(shè)計(jì)我做了以下工作 ： 。根據(jù)零件圖，合理的構(gòu)思出加工順序， 并數(shù)字化建模 ， 用 UG軟件畫出零件的立體圖，并選擇 毛坯材料和尺寸。加工的零件是對稱的圖形， 一零件的幾何中心為進(jìn)刀點(diǎn)，也作為程序的原點(diǎn)。臺虎鉗足以滿足零件裝夾的要求。球面用φ 6 球面銑刀加工。 工程序 的 編制。使用了 G68旋轉(zhuǎn)固定循環(huán)。根據(jù)工藝 卡片 的要求 分先后 分別進(jìn)行粗精加工 。s characteristic, is getting more and more widespread in machinebuilding industry39。s position. This graduation project is carries on the analysis and the establishment about some ponents processing craft and the procedure, in this design, through to the ponents graph analysis, the material analysis, chose the processing blank dimension, in addition to processing working procedure. The craft carries on the analysis, thus the handwork will process the code which, the program format the ponents the plete technological process, the technological parameter, the displacement data and so on stipulated to write, established has suited chooses milling machine39。 geometric center is the feed spot, also as procedure zero point. The nonprocessing39。s request. The bench vise satisfies the request which sufficiently the ponents attire clamps. The processing ponents 2 choice reasonable stage prop, the rough milling semifinished materials quantity is big, carries on the processing with the face milling cutter, other uses φ 6 end mill processing. The spherical surface processes with φ 6 the spherical cutter. Figures out the cutting specifications according to the cutting tool and the po
