内容简介:
就业前景:进入21世纪,更多企业已意识到机械制造的重要性。据国家轻工业局副局长朱焘介绍,现代工业产品的市场,在很大程度上依赖工业的成功。随着高科技技术的发展,产品的质量不再是主要矛盾,抢占市场,获胜的关键在于机械的创新,在于其能否引导世界潮流。今天的汽车、手机、电脑市场中,各企业越来越关注其设计问题,谁的工业设计有创新能取胜,谁就能赢得市场。目前国外许多大企业都拥有庞大的设计机构,象日本东芝,拥有的机械设计师数以百计。还有国内大企业海尔集团,就高薪聘用了多名外国机械设计专家,每年投入的开发设计费达8000多万元。这些高投入获得了高回报,海尔产品广泛行销海外世界市场就是一个证明。这说明,市场需求更多的机械设计就业人才,机械设计越来越在市场受到重视,起到举足轻重的作用。 中国加入WTO在即,只有机械设计人才得到重视、使用,我国的工业产品才能跻身广阔的世界市场,市场需要多层次、多门类的机械设计人才,机械设计人才在未来有极大的升值潜力。机械设计将是一个为我们国家、我们的企业大量创造知识产权的黄金水道。作为机械设计师,一方面是要大量地学习这些新知识,要有对知识的整合能力;另一方面是文化的积淀,这种文化的积淀也不是我们读几本好书,把古代的某个物品搬出来,把它翻翻新,这就叫创新了,而是怎么去结合中国文化元素,提取当中的文化底蕴的东西,这又是一个需要修炼的内功;第三点是作为机械设计师,对手段的能力要强,从做机械设计的角度上来讲,你所掌握的计算机软件要远远多于做平面和装璜的。机械设计除了有CAID等辅助工业设计的软件以外,还有许多的渲染、结构的软件,像CAD、PROE等各种加工的软件,直至和加工设备的接口的编程,这都需要工业设计师掌握和了解。所以机械设计师在世界上之所以能够成为高端的人才,他应该是从整体的设计业务当中成长起来的最高端的一批 也是这个专业的学生,毕业没多久,在这里说一点自己的看法吧。这个专业的工作很好找,至少在浙江是这样的,遍地都有需要这个专业的工厂。但是这个工作也很难找,怎么说呢,这里面有一点很重要,就是你的专业水平,如果你专业过硬,那么你在学校就可以同一些大企业达成就业协议,比如三一重工,吉利汽车,常石造船等等,着眼今后,可以这样说,机械行业将焕发生机。经过数年的改革调整,我国的机械企业逐步摆脱了计划经济的束缚,确立了现代企业制度,机械行业逐步跟上市场经济和信息时代的步伐;而且,随着形势的发展,中国的制造业将得到较大的发展,有专家预测,21世纪的中国很可能成为全球的制造业和加工工业中心,在这种形势下,对机械的需求必将有较大的提升。行业得到发展,继而会对用人提出数量方面和质量方面的要求,因此专家预测,机械类专业人才的就业需求将得到改善,甚至有可能出现“热销”局面,高层次的技术人才将成为企业竞相争夺的对象。在今后10年内,社会对机械行业毕业生总体需求较大,其中机电一体化专业人才最为紧缺。目前不少企业的生产设备逐步更新换代,掌握机电一体化技术、懂得数控设备的操作与维护的机械专业人才将大受欢迎。不过目前我国高校的一些机械类专业教学内容陈旧,不能适应培养高水平的机电一体化专业人才的需要,这是一个亟待解决的问题。此外机械设计制造与加工专业人才近年供需比也较高。因为这些专业将来的工作条件相对艰苦,需要从事车、钳、铣、刨等工作,所以报读这些专业的人不多,因而相关岗位上的人才缺口比较大。现在在不少地方的人才市场上,高级机械技术工人的待遇已直逼高学历人士。另外工业工程和工业设计专业也有望成为热门专业,因为我国的工业设计人才相对缺乏,我们20年来所培养的工业设计专业毕业生仅3万人左右,只相当于目前韩国该专业在校生的数量。从行业发展看,数控机床、工程机械、发电设备、印刷机械等专业的前景都值得看好,需要说明的是,机械类专业的名称、内涵过去和今天有所不同,现在经调整、合并,机械类专业有“机械设计制造及其自动化”“材料成型及控制工程”“工业设计”“过程装备与控制工程”“机械工程及自动化”“车辆工程”“机械电子工程”“汽车服务工程”“制造自动化与测控工程”“微机电系统工程”“制造工程”等专业。以下数据是俩年前的,没找到最新的毕业生就业率:92.01%。 热门分析:它是以培养现代机械工程师为目的的专业,也是我国高校开设得最久的专业之一。多年来,它长盛不衰的奥秘就在于:无论一个社会的文明发展到何等程度,都离不开机械制造,它是人们物质生活用品供应的基本保障。 考生类别:理工类。 就业前景:主要到工业生产第一线从事机械制造领域内的设计制造、科技开发、应用研究、运行管理和经营销售等方面的工作。 就业分布最多五省市:北京、上海、浙江、辽宁、山东。 毕业生就业分布统计: 就业行业或部门 百分率 国有企业 34.35% 录取研究生 14.68% 民营及私营企业 12.59% 其他事业单位 1.10% 高等学校 1.23% 机关 1.24% 科研设计单位 7.94% 三资企业 12.14% 部队 3.54% 中小学及其它教学单位 0.99% 出国 1.43% 自主创业 0.43% 金融单位 0.25% 医疗卫生单位 0.08% 注:本专业的各方向及就业率分别是:机械制造工艺与设备88.68%、机械设计及制造82.72%、汽车与拖拉机81.61%、机车车辆工程91.44%、流体传动及控制84.53%、真空技术及设备88.89%、机械电子工程88.44%、设备工程与管理85.63%、金属材料与热处理87.23%、铸造84.47%、塑性成型工艺及设备92.46%、焊接工艺及设备92.79%。机械是目前就业率很高的专业,但是赚钱多少要看你以后的能力,一般研究生在北方4000左右,本科生3000左右. 二、发展方向:柔性化使工艺装备与工艺路线能适用于生产各种产品的需要,能适用于迅速更换工艺、更换产品的需要。在技术上要实现柔性化。本世纪初,超精密加工精度可达到1nm。超精密加工目前包含超精密切削、超精密磨削研磨和精密特种加工等三个方面。超精密加工能提高产品的性能和质量,提高其稳定性和可靠性,促进产品的小型化,增强零件的互换性,提高装配生产率,促进自动化装配。超精密加工技术的发展有力地推动了各种新技术的发展,促进了最新科学技术的进步。同时微型机械大大发展。微型机械尺寸在1nm1m的机械。它是集微型机构、微型传动器以及信号处理和控制电路,甚至外围接口电路、通讯电路和电源等为一体的微型机电系统。它远远超出了传统机械的概念和范畴,其应用领域相当广泛。在将来,机器人将被更为广泛的应用于生产。为适应柔性自动化的需要,机器人必须有视觉系统,能对装配件的形体与姿态进行识别,应装有位置与触觉传感器,进行精确定位与抓握力的控制,自动导引车也应有视觉或声发射传感器,用以发现行进中可能有的障碍物等。越是柔性化的过程,越需要传感器。当然在以人为本的发展的社会中,生产过程中仅仅有技术上的柔性还是不够的,还要求在管理上的柔性。这也就是产生了一些新的生产模式。像精益生产特别强调“准时化”管理和人因的发挥,努力消灭一切浪费现象以获得最好的效益,强调企业的一切活动都离不开人的参与,尊重人性、调动人的积极性、增强员工的自主精神和责任感,其柔性范畴扩大到人员。而敏捷制造极富创造性地构建了一种企业的动态联盟 虚拟公司,以便能灵活快速地对市场变化做出积极的响应,使整个制造生产系统无论在技术、管理或是人员、组织上都具备充分的柔性,尤其强调了组织的柔性。在日益强调环保的今天,柔性化也体现在清洁生产。制造技术应是一项与环境协调的技术,它应该是一项遵循“可持续发展(sustainabledevelopment)”原则的技术。Employment prospects: entering the 21st century, more firms have come to realize the importance of mechanical manufacturing. According to the national light industrial bureau deputy director ZhuDao introduction, the modern industrial products in the market, to a large extent depend on industrial success. Along with the development of technology, the quality of the products is no longer the main contradiction, seizes the market, the keys to winning mechanical innovation, lies in its can lead the world trend. Todays car, mobile phones, computers in the market, the enterprise pay more and more attention to its design problem, who industrial design has innovation can win, who can win the market. At present many foreign big enterprise have enormous design organization, as the Japanese Toshiba, with mechanical designer hundreds. Large enterprises and domestic haier group, is gainfully employed a foreigner mechanical design expert, a year into development cost 8,000 yuan. These high investment obtained high return, haier products widely marketing overseas markets around the world is a proof. This shows that the market demand more mechanical design employment personnel, mechanical design more and more on market attention, played an important role. Chinas entry into the WTO, only mechanical design talents soon get attention, use, the countrys top industrial products to the wide world market, market need mutiple level, many categories of mechanical design talents, mechanical design talents in the future has great appreciation potential. Mechanical design will be a for our country, our enterprises create intellectual property of gold waterway. As mechanical designers, on the one hand is to massively learning these new knowledge, must have the ability to integrate knowledge; On the other hand is culture accumulation, this culture accumulation nor we read a few good books, the ancient a certain item move out put it through new. This is called innovation, but how to combine China cultural elements, extraction of culture of things, this is a uniting the internal strength; need The third point is as mechanical designers, the ability of means stronger mechanical design, from the Angle of do you master terms, computer software to do far more than the plane and decoration. Mechanical design besides have CAID auxiliary industrial design software, besides the many rendering, structure of software, like CAD, various processing software PROE, until and processing equipment interface programming, this needs industrial designer knowledge and understanding. So mechanical designer in the world are able to become high-end talent, he should from general design business grew up the top of the line Is the specialized student, graduation before long, here to say his own view right away. The professional work well to find, at least in zhejiang is such, everywhere all have need this professional factory. But this work also was hard to find, how to say, there is whats important your professional level, if you professional in school, then you can be the same some big enterprises, such as employment agreement reached at trinity ChangShi dhi, geely automobile, shipbuilding, etc, focus on the future, it can be said that mechanical industry will vitality. After several years of reform, China mechanical enterprises adjustment from planned economy gradually the fetter, established the modern enterprise system, mechanical industry gradually keep up with market economy and the pace of the information age; And, as the development of the situation, Chinas manufacturing will get bigger development, experts predict the 21st century, China is expected to become the global manufacturing and processing industrial center, in this situation, the demand of mechanical there will be bigger promotion. Industry to develop forward, then choose and employ persons and the quality aspect of the number of requirements, so experts predict, mechanical engineering talent employment demand will improve, even appear likely sell situation, high-level technical personnel will become the object of competing for enterprises. Over the next 10 years of mechanical industry, society, including the overall demand for more graduates of mechatronics professionals most shortage. At present many enterprise production equipment gradually renewal, grasps the electromechanical integration technology, understand CNC equipment operation and maintenance of the machinery professionals will be very popular. But now some of the colleges and universities in China mechanical engineering teaching content dated, can not adapt to cultivate high levels of mechatronics specialized talented persons demand, this is a problem. Besides mechanical design, manufacturing and processing professional talents in recent years than also higher in supply and demand. Because these professional future work conditions, need engaged in relatively hard car, grips, milling, planing, etc, so to enrolling these professional, and few people on the relative position of the talent gap is larger. Now the talent market in many places, a senior mechanical technical workers who already hit the treatment well educated. Another industrial engineering and industrial design major also is expected to become popular major, because our industrial design talents, we 20 years relative lack of cultivated by industrial design graduates only 3 million or so, only the equivalent of the professional students now South Korea quantities. From industry development look, nc machine tools, engineering machinery, power generation equipment, printing machinery and other professional prospect are worth adance, need explanation is, machinery specialized name, connotation, past and present different by adjustment, merger, now in mechanical engineering have mechanical design, manufacturing and automation material molding and control engineering industrial design process equipment and control engineering mechanical engineering and automation vehicle engineering mechanical and electronic engineering car service engineering manufacturing automation and measurement &control engineering microelectromechanical system engineering manufacturing engineering, and other professionals. The following data is two years ago, didnt find the latest Graduates: 92.01%. Popular analysis: it aims at developing modern mechanical engineer for the purpose of professional, China is the college offers one of the most long professional. For many years, it is the key to longevity of a society: no matter how degree of civilization, is inseparable from the machinery manufacturing, it is people physical life of the basic safeguard supplies. The examinee category: science &engineering. Employment prospects: mainly to industrial production machinery manufacturing field front-line engaged in the design and manufacture, science and technology development and application research, operation management and business sales, etc. Employment distribution most five provinces and cities: Beijing, Shanghai, zhejiang, liaoning, shangdong. Graduates employment distribution statistics: Employment industries or departments percentage 34.35% state-owned enterprises 14.68% admitted to graduate 12.59% private and private enterprise Other institutions 1.10% Higher school 1.23% Authorities 1.24% 7.94% scientific research units 12.14% three-capital enterprise Troops 3.54% Schools and other teaching units 0.99% 1.43% abroad 0.43% self-employed Financial unit 0.25% Medical unit (0.08%) Note: this professional each direction and employment respectively is: mechanical manufacturing technology and equipment 88.68%, mechanical design and manufacturing 82.72%, automobile and tractor 81.61%, locomotive vehicle engineering 91.44%, fluid transmission and control 84.53%, vacuum technology and equipment 88.89%, machinery and electronics engineering 88.44%, equipment engineering and management 85.63%, metal material and heat treatment 87.23%, casting 84.47%, plastic molding process and equipment 92.46%, welding technology and equipment 92.79%. Machinery is the employment rate high professional, but how much money you should see you later ability, general graduate student in northern 4000, undergraduate 3000 or so. Second, developing direction: flexibility - making craft equipment and process route can be applicable to the production of product needs, can apply to quickly replace process, replacement product needs. In the technology to realize the flexible. At the beginning of this century, the ultra precision machining precision can reach 1nm. The ultra precision processing currently contains the ultra precision cutting and ultra-precision grinding grinding and precision special processing from three aspects. The ultra precision processing can improve product performance and quality, improve its stability and reliability, to promote the product miniaturization, enhance the interchangeability, improve assembly parts, promote productivity automated assembly. Ultra-precision processing technology development vigorously promoted the development of all kinds of new technology, promote the latest development of science and technology. Meanwhile micro machines greatly development. Micro mechanical sizes in 1nm 1 muon m machinery. It is the collection miniature institutions, miniature clutch and signal processing and control circuit, even peripheral interface circuit, communication circuit and power as a miniature mechanical and electrical system. It went far beyond the traditional mechanical concept and category, its application field quite extensive. In the future, the robot will be more widely used in production. In order to adapt to the need of flexible automation, the robot must have the visual system to the assemblies, can form and attitude should be fitted with identification, the position and tactile sensor, precise positioning and grasp the control, automatic grip DaoYinChe due also and visual or acoustic emission sensor to find possible obstacles in walking. The more flexible process, need more sensors. Of course in to the people-centered development society, production process only has technical flexible or not enough, also requires on management flexibility. This also is produced some new production mode. Like lean production special emphasis on just-in-time management and people because of the play, efforts to eliminate all waste phenomenon to obtain the best benefit, emphasizing the enterprise all the activities of the participation of is inseparable from the people, respect for humanity, aroused peoples enthusiasm, enhancing employees independent spirit and responsibility, its flexible category expanded to personnel. And agile manufacturing extremely creatively constructed an enterprise dynamic union - virtual company, so that can flexibly to market changes quickly make a positive response, make whole manufacturing production system no matter in technology, management or personnel, organization has sufficient flexibility, especially emphasized the organizations flexibility. In an increasingly emphasize environmental protection today, flexible also reflect in the cleaner production. Manufacturing technology should be a and harmonious environment technology, it should be a follow sustainable development sustainable development (principle of technology. 机械加工工序卡片产品型号零件图号产品名称旋耕机零件名称犁刀变速齿轮箱体共13页第1页 车间工序号工序名称材 料 牌 号10粗铣N面HT200毛 坯 种 类毛坯外形尺寸每毛坯可制件数每 台 件 数铸 件17716815011设备名称设备型号设备编号同时加工件数立式铣床X52K1夹具编号夹具名称切削液粗铣N面夹具工位器具编号工位器具名称工序工时 (分)准终单件工步号工 步 内 容工 艺 装 备主轴转速切削速度进给量切削深度进给次数工步工时r/minm/minmm/rmm机动辅助1粗铣N面专用铣夹具11874.123.51可转位面铣刀 200 设 计(日 期) 校 对(日期) 审 核(日期) 标准化(日期) 会 签(日期)标记处数更改文件号签 字 日 期标记处数更改文件号签 字 日 期机械加工工序卡片产品型号零件图号产品名称旋耕机零件名称犁刀变速齿轮箱体共13页第2页车间工序号工序名称材 料 牌 号20钻扩铰29,钻413HT200毛 坯 种 类毛坯外形尺寸每毛坯可制件数每 台 件 数铸 件17716815011设备名称设备型号设备编号同时加工件数立式钻床Z30251夹具编号夹具名称切削液钻N面夹具工位器具编号工位器具名称工序工时 (分)准终单件工步号工 步 内 容工 艺 装 备主轴转速切削速度进给量切削深度进给次数工步工时r/minm/minmm/rmm机动辅助1钻孔413专用钻夹具63025.70.46.510.440.6052钻孔27卧轴分度台 5001000220.33.510.10.373扩钻孔28.8,孔口倒角145麻花钻 13、7400110.30.910.220.334铰孔29扩孔钻8.863017.80.30.110.140.63 设 计(日 期) 校 对(日期) 审 核(日期) 标准化(日期) 会 签(日期)标记处数更改文件号签 字 日 期标记处数更改文件号签 字 日 期机械加工工序卡片产品型号零件图号产品名称旋耕机零件名称犁刀变速齿轮箱体共13页第3页车间工序号工序名称材 料 牌 号30粗铣R面、Q面HT200毛 坯 种 类毛坯外形尺寸每毛坯可制件数每 台 件 数铸 件17716815011设备名称设备型号设备编号同时加工件数立式铣床1夹具编号夹具名称切削液粗铣R及Q面夹具工位器具编号工位器具名称工序工时 (分)准终单件工步号工 步 内 容工 艺 装 备主轴转速切削速度进给量切削深度进给次数工步工时r/minm/minmm/rmm机动辅助1粗铣R及Q面专用铣夹具120602R面3.51 设 计(日 期) 校 对(日期) 审 核(日期) 标准化(日期) 会 签(日期)标记处数更改文件号签 字 日 期标记处数更改文件号签 字 日 期机械加工工序卡片产品型号零件图号产品名称旋耕机零件名称犁刀变速齿轮箱体共13页第4页车间工序号工序名称材 料 牌 号40铣凹台面HT200毛 坯 种 类毛坯外形尺寸每毛坯可制件数每 台 件 数铸 件17716815011设备名称设备型号设备编号同时加工件数立式铣床X52K1夹具编号夹具名称切削液铣凹台面夹具工位器具编号工位器具名称工序工时 (分)准终单件工步号工 步 内 容工 艺 装 备主轴转速切削速度进给量切削深度进给次数工步工时r/minm/minmm/rmm机动辅助1粗铣R面、Q面专用铣夹具30075.41.241莫氏锥柄面铣刀 80 设 计(日 期) 校 对(日期) 审 核(日期) 标准化(日期) 会 签(日期)标记处数更改文件号签 字 日 期标记处数更改文件号签 字 日 期机械加工工序卡片产品型号零件图号产品名称旋耕机零件名称犁刀变速齿轮箱体共13页第5页 车间工序号工序名称材 料 牌 号50粗镗孔280,倒角HT200毛 坯 种 类毛坯外形尺寸每毛坯可制件数每 台 件 数铸 件17716815011设备名称设备型号设备编号同时加工件数组合机床1夹具编号夹具名称切削液粗镗孔夹具工位器具编号工位器具名称工序工时 (分)准终单件工步号工 步 内 容工 艺 装 备主轴转速切削速度进给量切削深度进给次数工步工时r/minm/minmm/rmm机动辅助1粗镗孔280,倒角专用镗模96240.22.751塞规79.5H10 镗杆、镗刀、倒角刀 设 计(日 期) 校 对(日期) 审 核(日期) 标准化(日期) 会 签(日期)标记处数更改文件号签 字 日 期标记处数更改文件号签 字 日 期机械加工工序卡片产品型号零件图号产品名称旋耕机零件名称犁刀变速齿轮箱体共13页第6页 车间工序号工序名称材 料 牌 号60精铣N面HT200毛 坯 种 类毛坯外形尺寸每毛坯可制件数每 台 件 数铸 件17716815011设备名称设备型号设备编号同时加工件数卧式铣床X61321夹具编号夹具名称切削液精铣N面夹具工位器具编号工位器具名称工序工时 (分)准终单件工步号工 步 内 容工 艺 装 备主轴转速切削速度进给量切削深度进给次数工步工时r/minm/minmm/rmm机动辅助1精铣N面专用铣夹具300188.40.51.51可转位面铣刀200 刀口尺 设 计(日 期) 校 对(日期) 审 核(日期) 标准化(日期) 会 签(日期)标记处数更改文件号签 字 日 期标记处数更改文件号签 字 日 期机械加工工序卡片产品型号零件图号产品名称旋耕机零件名称犁刀变速齿轮箱体共13页第7页 车间工序号工序名称材 料 牌 号70精扩铰孔210 HT200毛 坯 种 类毛坯外形尺寸每毛坯可制件数每 台 件 数铸 件17716815011设备名称设备型号设备编号同时加工件数摇臂钻床Z30251夹具编号夹具名称切削液精扩铰孔210夹具工位器具编号工位器具名称工序工时 (分)准终单件工步号工 步 内 容工 艺 装 备主轴转速切削速度进给量切削深度进给次数工步工时r/minm/minmm/rmm机动辅助1扩孔29.9F9 专用钻夹具40012.40.30.9512精铰孔210F7 扩孔钻9.9 63019.80.30.951铰刀10F7塞规10F7 设 计(日 期) 校 对(日期) 审 核(日期) 标准化(日期) 会 签(日期)标记处数更改文件号签 字 日 期标记处数更改文件号签 字 日 期机械加工工序卡片产品型号零件图号产品名称旋耕机零件名称犁刀变速齿轮箱体共13页第8页 车间工序号工序名称材 料 牌 号80精铣R面及Q面HT200毛 坯 种 类毛坯外形尺寸每毛坯可制件数每 台 件 数铸 件17716815011设备名称设备型号设备编号同时加工件数组合铣床1夹具编号夹具名称切削液精铣Q面及Q面夹具工位器具编号工位器具名称工序工时 (分)准终单件工步号工 步 内 容工 艺 装 备主轴转速切削速度进给量切削深度进给次数工步工时r/minm/minmm/rmm机动辅助1精铣R面、Q面专用铣夹具240120120.51可转位面铣刀160 专用检具 设 计(日 期) 校 对(日期) 审 核(日期) 标准化(日期) 会 签(日期)标记处数更改文件号签 字 日 期标记处数更改文件号签 字 日 期机械加工工序卡片产品型号零件图号产品名称旋耕机零件名称犁刀变速齿轮箱体共13页第9页 车间工序号工序名称材 料 牌 号90精镗孔280H7 HT200毛 坯 种 类毛坯外形尺寸每毛坯可制件数每 台 件 数铸 件17716815011设备名称设备型号设备编号同
