量的切削液。与传统的湿切削相比,降低了加 工成本,避免了废液的处理。
2先进生产制造模式
在社会经济快速发展和市场竞争日益激烈 的今天,制造企业仅仅依靠改进工艺、提高装
备水平是满足不了上述要求的,必须从总体策略、组织结构 、管理模式等方面适应市场的要
求,制造模式是指企业体制、经营、管理、生产组织和技术系统的形态和 运作模式。
a)精益生产(LP):1990年美国麻省理工学院詹姆斯等花了5年时间考察全球近百 家汽车
制造厂,在《TheMachineThatChangedtheworld》一书中提出精益 生产概念。并依此来描
述日本丰田汽车公司生产方式,认为日本20世纪80年代成功的原因在于采用了 新型的生产
模式。
精益生产的的特点是:1)以人为本,调动所有员工的积极性和创造性;2 )重视顾客需要,
按顾客的需要提供适销对路的产品,并提供优质服务;3)精打细算,消除制造过程中 一切冗
余的人、物、活动、岗位、时间、空间,要求工人一专多能,实现完美生产;4)精益求精,追求制造过程中各个环节和全过程的不断完善,及时解决问题,实现零废品、零库存和产品
的多样化 。
b)敏捷制造(AM)与虚拟企业(VE):20世纪80年代,为了恢复美国制造业在全球的领导
地位,由美国国防部组织了里海大学和通用汽车公司等13家大公司为核心的有100多家公司
参与的联合研究组,最终于1991年完成了《21世纪制造业发展战略》报告并提交美国国会,
此报告 提出了“敏捷制造”的概念。
敏捷制造的特点:1)需求响应的快捷性,快速响应市场当前和未来可预 知需求,开发、
生产符合用户设计或订货要求的产品;2)制造资源的集成性,不仅是企业内部的资源共 享与
信息集成,还包括企业间的各种资源集成起来,实现技术、管理和人的集成,从而在产品的
生命周期内,最大限度地满足用户的需要;3)组织形式的动态性,为赢得机遇性市场竞争,
利用信息技 术和网络技术,实现不同组织和企业间的动态组织,它随任务的产生而产生,并
随任务的结束而结束,这 种超越审问的互利互惠、协同作战、资源互补的联合组织,被称为
虚拟企业,又称为动态联盟。
1993年,美国圣地亚国家实验室、联合信号公司联合实施了遥测装置敏捷制造示范项
目,在13个 月内设计和制造了新型集成遥测处理器,项目成本比预算降低了30%多,生产
时间比以前的生产方式减 少50%,生产效益提高好几倍。
2000年2月,通用汽车公司、福特汽车和戴姆勒一克莱斯勒终止 各自的零部件采购计划,
转向共同建立零部件采购的电子商务市场(采购环节的动态联盟),同年4月, 雷诺一日产公
司决定加盟该电子商务市场,交易处理成本由原来的每笔100~150美元降低到5美元 ,每台
汽车的制造成本至少可以降低1200美元。
C)集成制造(CIM)与智能制造(I M):1974年,美国的哈林顿博士在
《ComputerIntegratedManufactu ring)一书中提出计算机集成制造(CIM)的概念。集成制造
的两个基本观点是:1)系统观,企 业的各个经营环节,从市场、产品的开发、加工制造、管
理、销售及服务都是一个不可分割的整体,需要 统筹考虑;2)制造信息观,企业整个生产经
营过程,实际上是信息采集、传递和加工处理的过程。 < br>CIM是企业组织、管理和实现现代化生产的新模式,它将企业的人、技术、管理三要
素以及信息 流、物料流、价值流有机地集成在一起,逐步实现企业全过程的计算机化综合,
它能使企业在总体优化的 前提下,寻求局部优化并达到全局优化运行,以获得最大效益。
IM是在20世纪80年代人工智能技 术广泛应用的基础上产生的,它的特点是:制造的各
个环节的高度柔性化、高度集成化和智能化,通过计 算机来模拟人类专家的智能活动,对制
造问题进行分析、判断、推理、构思和决策,取代或延伸制造环境 中人的部分脑力劳动,并
对人类专家的制造智能进行收集、存储、完善、共享、继承与发展。
3结语
近年来,中国先进制造技术在政府的引导和扶持下,得到快速的发展和重大突破。计算
机辅助设计技术(CAD)在制造业普遍应用,我国开发了一批性能优异的三维CAD,CAPP
和CAM系统,数控机床和柔性制造系统也取得了丰硕的成果。基础技术和系统技术方面的
发展,极大 地推动了制造业的现代化。发展和推广先进的制造技术要站在信息技术科技革命、
纳米科技革命和生物科 技革命的高度,充分认识先进制造技术需要的是创新型人才,实施先
