數控零件加工工藝與編程畢業設計畢業論文(已修改)

　

【正文】 數控零件加工工藝與編程CNC Parts Machining Technology and Programming摘 要 數控加工因為其高柔性、高精度、高度自動化與高效率的特點，在機械制造業中的應用越來越廣泛，在當今社會的位置越來越重要。本次設計我使用手動編程。本次畢業設計是關于某個零件的加工工藝與程序進行分析與編制，在本次設計中,通過對零件的圖形分析,材料分析,選好了加工毛坯尺寸,從而手工將加工零件的全部工藝過程、工藝參數、位移數據等以規定的代碼、程序格式寫出,編制出了適合所選銑床的程序。完成這次設計我做了以下工作：。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雜的結構，對加工的程序要求高。根據零件圖，合理的構思出加工順序，并數字化建模，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刀點，也作為程序的原點。非加工的邊緣四周區域是正方形，所以方便裝夾，對夾具的要求不高。臺虎鉗足以滿足零件裝夾的要求。加工零件選擇合理道具，粗銑毛坯量大，用面銑刀進行加工，其余的用φ6的立銑刀加工。球面用φ6球面銑刀加工。根據刀具和零件的要求算出切削用量，制定工藝卡片。手動編寫出零件的加工程序，零件的程序中應用到了倒圓角的宏程序，球面的宏程序，二次曲線的宏程序。使用了G68旋轉固定循環。零件加工的是內部結構，所以由上之下，由中間到四周進行加工。根據工藝卡片的要求分先后分別進行粗精加工。關鍵詞: 零件的分析 裝夾 工藝 編程 宏程序AbstractBecause the numerical control processing its high flexibility, the high accuracy, highly automated and the high efficiency39。s characteristic, is getting more and more widespread in machinebuilding industry39。s application, is now getting more and more important in society39。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。s procedure. 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。 geometric center is the feed spot, also as procedure zero point. The nonprocessing39。s edge all around region is a square, therefore the convenient attire clamps, is not high to jig39。s request. The bench vise satisfies the request which sufficiently the ponents attire clamps. The processing ponents choice reasonable stage prop, the rough milling semifinished materials quantity is big, carries on the processing with the face milling cutter, other uses φ6 end mill processing. The spherical surface processes with φ6 the spherical cutter. Figures out the cutting specifications according to the cutting tool and the ponents request, the formulation process chart. numerical control milling machine ponents add the project the foreword establishment. Manual piled the ponents the processing program, in the ponents procedure applies the round angle great procedure, the spherical surface great procedure, the conic section great procedure. Used G68 to revolve the fixed cycle. What ponents processing is the internal structure, therefore from, to all around carries on the processing from among.
