摘要: M5-5加強(qiáng)板零件是某航空產(chǎn)品中的一個(gè)薄壁零件，主要起支撐作用因而需要一定的強(qiáng)度和剛度，它是采用LC9鋁合金材料，能滿足其性能要求。航空產(chǎn)品一般是單件小批量生產(chǎn)，故適宜采用數(shù)控加工生產(chǎn)。本畢業(yè)設(shè)計(jì)課題的設(shè)計(jì)內(nèi)容主要包括M5-5加強(qiáng)板零件數(shù)控加工和鉆孔用組合夾具拼裝兩個(gè)部分。數(shù)控加工部分主要有零件的實(shí)體模型的建立、數(shù)控加工工藝規(guī)程編制、刀具、切削用量及主軸轉(zhuǎn)速的選擇，以及零件的仿真數(shù)控加工，并利用UG軟件自動(dòng)生成相應(yīng)工序的數(shù)控加工程序。實(shí)體模型的建立是利用UG現(xiàn)有的塊、圓柱體、圓錐體和球體四種簡單的實(shí)體模型，通過建模合理性和參數(shù)化要求出發(fā)，根據(jù)M5-5加強(qiáng)板零件的特點(diǎn)創(chuàng)建符合數(shù)控加工的實(shí)體模型。根據(jù)粗、精加工分開的原則合理編制數(shù)控加工工藝規(guī)程。根據(jù)工件材料及所用機(jī)床選擇適合的刀具及切削用量。組合夾具拼裝部分主要有組合夾具的總體設(shè)計(jì)、相關(guān)組合夾具元件的選擇，定位基準(zhǔn)的選擇及夾緊方法的選擇以及加工誤差精度分析。

Abstract : M5-5 Strengthen the plank part some aviation products one of frame thin wall part, it need certain intensity and rigidity to play a supporting role mainly, it adopts the aluminium alloy material of LC9, can meet its performance demand . Aviation products single piece light to produce in batches generally, is it adopt numerical control process production to suit. Aviation products single piece light to produce in batches generally, is it adopt numerical control process production to suit. This graduation project design of subject content mainly including M6-6 little floor part numerical control process and hole with make up jig assemble two parts. Numerical control process part for entity foundation , numerical control processing technology rules make , cutter , cut consumption and choice , main shaft of rotational speed of model of part, and artificial numerical control of part process, utilize UG software turn into corresponding numerical control of process process the procedure automatically. Foundation, entity of model to utilize UG existing piece , round cylinder , cone , spheroid 4 kinds of simple entity models, is it set out to demand through modeling rationality and parameter , is it accord with the entity model processed in numerical control to establish according to M5-5 Strengthen the plank characteristic of part. According to thick, principle that finish machining separate work out the processing technology rules of numerical control rationally. And choose the suitable cutter and cutting consumption with the lathe according to the work piece material. Making the jig up has overall design which makes the jig up , relevant choices of making the jig component up to assemble mainly, orient the basic choice and choice of clamping the method and process the analysis of precision of error.
