【正文】 t: machinery manufacturing processing technology in human production practice and manufacturing processing machinery manufacturing industry is the foundation, is the production of hightech products to it unable to develop advanced products and ensure the quality of products, reduce the cost and shorten the production cycle, improve productivity, therefore, a good processing technology and program, deciding an enterprise economic benefits.This paper mainly introduces the mechanical product plane groove cam machining process design and program editing, including: parts of the plan, parts of the process analysis, design process, selection of machine tools and processing equipment, determine the cutting quantity, determine the process and take the knife line, parts machining process card, NC machining process card, NC machining tool cards, process design, preparation process, and the preparation of documents processing procedure.In addition to the introduction of planar parts processing technology design and machining process design, also introduced the machinery manufacturing machining process and program editing in machinery manufacturing industry and the role of mechanical manufacturing technology current situation and development.In the design of the school on the selection of location datum, the workpiece positioning method of box part structure, process analysis.At the same time in the graduation design also applies to MAutoCAD, UG drawing functions and mstercam simulation processing and automatic program editing function.This graduate design reflects the machinery manufacturing processing technology and fixture design of the purpose is: to ensure and improve product quality。平面槽形凸輪零件加工工藝設(shè)計(jì)及編程摘要:機(jī)械制造加工工藝技術(shù)是在人類生產(chǎn)實(shí)際中產(chǎn)生并不斷發(fā)展的。本畢業(yè)設(shè)計(jì)說明書反映了機(jī)械制造加工工藝與夾具設(shè)計(jì)的宗旨是:保證和提高產(chǎn)品質(zhì)量;提高勞動(dòng)生產(chǎn)率;提高經(jīng)濟(jì)效益。機(jī)械制造工藝與夾具設(shè)計(jì)是以機(jī)械制造中的加工問題為對(duì)象的一門技術(shù)科學(xué)。這個(gè)基礎(chǔ)是否牢固直接影響到一個(gè)國(guó)家的經(jīng)濟(jì)發(fā)展和綜合國(guó)力,關(guān)系到一個(gè)國(guó)家的戰(zhàn)略地位。因此,數(shù)控編程的工藝處理是一項(xiàng)十分重要的工作。注意:,工件表面有凹槽,斜向切切切出,工件表面光滑。在數(shù)控加工中,加工工序往往較集中,以統(tǒng)一基準(zhǔn)定位十分重要,工藝基準(zhǔn)的統(tǒng)一也十分必要。因此應(yīng)先加工用作定位基準(zhǔn)的20,Ф12兩個(gè)孔然后再加工凸輪槽內(nèi)外輪廓表面。 切削用量的選擇 凸輪槽內(nèi)外輪廓精加工時(shí)留0101mm洗消余量,精鉸Ф20,Ф12。 3)本零件中的尺寸公差等級(jí)精度要求是:Ф12mm的通孔Ф12尺寸公差等級(jí)要求為H7,Ф20mm的通孔Ф20尺寸公差等級(jí)要求為H7。 2)用銑刀銑削高為17mm的臺(tái)階面。這樣按裝夾次數(shù)為劃分工序的依據(jù),則該零件的加工主要?jiǎng)澐譃槿齻€(gè)工序。 2)加工18mm的臺(tái)階面并倒R2的圓角,可用Ф10mm的立銑刀,先粗銑再精銑。該機(jī)床工作臺(tái)尺寸為400mmX800mm,x軸行程為600mm,y軸行程為400mm,z軸行程為400mm。 圖 52 面銑刀 圖 53 中心鉆 圖 54 麻花鉆 擴(kuò)孔鉆 鏜刀 立銑刀 量具的選擇 根據(jù)零件的加工的尺寸要求,加工該零件選用千分尺、塞規(guī)、內(nèi)螺紋規(guī)等對(duì)該零件進(jìn)行測(cè)量及校準(zhǔn)即可。加工銑削Ф8F8的不規(guī)則形槽時(shí),主軸轉(zhuǎn)速為3000r/min。加工銑削Ф8F8的不規(guī)則形槽時(shí),進(jìn)給速度為1000r/min。精銑底面時(shí), 。1) 銑削底面的進(jìn)給路線 2) 銑削臺(tái)階面的進(jìn)給路線袁節(jié)膅薂羄肅
