前  言
这次是大学的最后一次设计，回想以前的多次设计，自己都不是很认真的对待，感觉上是学不到什么东西，而且大家到不是很投入去搞，自己也受了一定的影响，因此每次都差不多是在及格边缘挣扎。但是经历了假期的找工，就自然感觉到自己含“金”量的不足，所以这次毕业设计是一次很好的机会给我去尽自己的能力把大学所学的全部知识系统的复习一遍，使得自己能够更好的掌握所学知识，有个更加清晰的专业思路，为以后在工作打下坚实知识基础。
全力以赴，为能顺利毕业，打下漂亮一仗！

CAD/CAM technology
SUMMAR：CAD/CAM has been a popular technology for engineer production, here are some knowledge about it.
KEYWORDS: CAD, CAM, computer, production, draft
CAD/CAM is term which means computer-aided design and computer-aided manufacturing. It is the technology concerned with the use of digital computers to perform certain functions in design and production. This technology is moving in the direction of greater integration of design function, two activities which have traditionally been treated as distinct and separate functions in a production firm.Ultimately,CAD/CAM will provide the technology base for the computer-integrated factory of the future.
Computer-aided design（CAD）can be defined as the use of computer systems to assist in the creation,modification,analysis,or optimization of a design. The computer systems consist of the hardware and software to perform the specialized design functions required by the particular user firm. The CAD hardware typically includes the computer, one or more graphics display terminals,deybords,and other peripheral equipment. The CAD software typically includes the computer, one or more graphics display terminal,keyboards,and other peripheral equipment. The CAD software consists of the computer programs to implement computer graphics on the system plus application programs to facilitate the engineering functions of the user company. Examples of these application include stress-strain analyses of components, dynamic response of mechanisms, heat-transfer calculations, and numerical control part programming. The collection of application programs will vary from one user firm to the next because their product lines, manufacturing processes, and customer markets are different. These factors give rise to differences in CAD system requirements. There are the components of CAD/CAM system:
 
 
CAD/CAM SYSTEM HARDWARE
 SYSTEM SOFTWARE
 
CAD/CAM SYSTEM SOFTWARE DISPOSE
Computer-aided manufacturing （CAM）can be defined as the use of computer systems to plan,manage,and control the operations of a manufacturing plant through either direct or indirect computer interface with the plants production resources. As indicated by the definition, the applications of computer-aided manufacturing fall into two broad categories:
1）Computer monitoring and control. These are the direct applications in which the computer is connected directly to the manufacturing process for the purpose of monitoring or controlling the process.
2）Manufacturing support applications. These are the indirect applications in which the computer is used in support of the production operations in the plant, but there is no direct interface between the computer and the manufacturing process.
INCREASING DRAFTING PRODUCTIVITY
CAD/CAM systems can entail a whole new set of drafting philosophies, all of which enhance productivity. To take it one one step further, remember that entire designs can be stored on the system. When the drafter receives ajob that has specifications similar to a stored drawing ,he merely retrieves it ,brings it into working storage, and edits those portions of the design that are not consistent with the specifications of the new bob. Productivity increases are thus compounded. The original job is speeded up, and that job,in turn, is used to speedup the next job even further. This illustrates the need to maintain a complete and up-to-date data base that can be accessed easily by all users.
IMPROVING DESIGN ANALYSIS
Design analysis is another important task that can be handled automatically by a properly integrate CAD/CAMsystem.This particularly important in an application like piping plant design where drawings are often and must adhere to precise industry specifications. A CAN/CAM system with piping design applications software can give the user automatic feedback on such characteristics as fluid capacities, material chemistry, stress limitations, and coupling requirements. It can also generate orthographic plans, elevation data, equipment parts lists, cost estimates, flow diagrams, process and instrumentation diagrams, and bills of materials. The system can even access and control complex engineering analyses programs and provide instant feedback on the viability of various design alternatives.
               OTHER ANALYTICAL BENEFITS
CAD/CAM can influence a company engineering systems in many other ways as well. It can porting procedures. CAD/CAM improves and expedites quality assurance techniques, and it lends itself naturally to maintaining accurate and complete documentation and to keeping accurate records of part numbers and bills of materials.
WHAT ARE THE DRAWBACKS?
The drawbacks to CAD/CAM may not be so obvious, but they can be devastating to even the best plans. The most debilitating of these comes from the leap entailed in moving directly from manual drafting and record keeping to CAD/CAM. It is like putting a jet engine in Volkswagen. The car may go fast for a little while, but the whole thing will shake apart if the chassis is not reinforced sufficiently to handle the stress.
THE APPLICATION OF CAD/CAM
CAD/CAM technology has come a long way since SKETCHPAD. It is already being applied to a research, from cartography to sports medicine, from circuit analyses to structural steel analyses. CAD/CAM is being applied to all aspects of drafting and manufacturing, from drawing sketches for movie sets to directing enormous robots that assemble battleshiops.Its versatility is still being explored.
THE CAD/CAM MARKETPLACE TODAY
Today there are 4 different kinds of CAD/CAM vendors in the marketplace. First are the subsidiary companies that sell CAD/CAM technology from within a department or division of a larger corporation. The CAD/CAM division of IBM is an example, as is McAuto,owned by McDonnell-Douglas;Calma,owned by General Electric; and Applicon,owned by Schlumberger.Most of these CAD/CAM subsidiaries do a great deal of business with their parent companies, selling not only turnkey systems but acting as service bureaus. These companies are at their best when handling large accounts and providing service because they have such large resources from which to draw on.But they are also burdened with complex bureaucracies, which makes it difficult for them to react quickly to market trends or to incorporate into their product lines new technology developed out side their own research and development departments.

摘要：CAD/CAM已经成为当今工业设计，制造必不可少的技术，这里跟大家有关这一技术的知识。
关键词：CAD，CAM，计算机，生产，制图
CAD/CAM是专业术语，表示计算机辅助设计和计算机辅助生产。这是一项在设计和生产中，关于使用计算机数据去执行某些功能的技术。这项技术正向地完成设计和生产的方向发展。这两项传统上被认为是生产流程中与众不同的，独立的功能。总而言之，CAD/CAM会为将来的完全计算机生产提供技术基础。
从计算机科学的角度看，设计与制造的过程是一个关于产品的信息产生、处理、交换和管理的过程。人们利用计算机作为主要技术手段，对产品从构思到投放市场的整个过程中的信息进行分析和处理，生成和运用各种数字信息和图形信息，进行产品的设计与制造。CAD/CAM技术不是传统设计、制造流程的方法的简单映像，也不是局限于在个别步骤或环节中部分的使用计算机作为工具，而是将计算机科学与工程领域的专业技术以及人的智慧和经验以现代的科学方法为指导结合起来，在设计、制造的全过程中各尽所长，尽可能的利用计算机系统来完成那些重复性高、劳动量大、计算复杂以及单纯靠人工难以完成的工作，辅助而非代替工程技术人员完成整个过程，以获得最佳效果。CAD/CAM系统以及算计硬件、软件为支持环境，通过各个功能模块（分系统）实现对产品的描述、计算、分析、优化、绘图、工艺规程设计、仿真以及NC加工。而广义的CAD/CAM集成系统还应包括生产规划、管理、质量控制等方面。自1946年第一台电子计算机在美国诞生以来，人们就不断的将计算机技术   引入机械设计?制造领域。早在50年代，首次研制成功数控机床，通过不同的数控程序就可以实现对不同零件的加工。随后，麻省理工学院的伺服机构实验室成功用计算机制作数控纸带，实现了NC编程的自动化。在此基础上，人们提出了如下设想： APT程序系统是通过描述走刀轨迹的方法实现计算机辅助编程，那么，能不能不描述走刀轨迹，而是直接描述零件本身？由此产生了CAD的最初概念。整个50年代，电子计算机还处于电子管时期，使用机器语言编程，计算机主要用于科学计算，为之配置的图形设备也仅具输出功能。CADCAM系统的基本

计算机辅助生产（CAM）可以定义为使用计算机系统去设计、管理与控制一项生产计划的动作，通过直接或间接的计划生产资源的计算机界面。如定义所述，计算机辅助生产的应用有2大方面：
1）计算机监视控制。这是直接应用，把计算机直接与生产过程连接，用于监督和控制生产过程。
2）生产支持应用。这是间接应用，在生产计划当中，计算机用于支持生产操作，但不是计算机与生产过程的直接连结。
制图生产力的增加
CAD/CAM系统可以承担一整套新的制图理论会增强生产能力。再去完成下一步，牢记整个设计可以储存系统。当制图者接到　一与已存图纸规格相似的工件，他只需回想起，并将它调到工作贮藏库，修改原图纸中不符合新工件要求的一部分，生产能力而提高。原来的工件效率提高，而这又会提高下一步的工作效率。这是一个完整的时时更新的信息库支持，能方便使用者使用。
改善制图分析
制图分析是另一项重要的工作，它能由某些综合CAD/CAM系统自动操作。这在管道设计中，尤其是一项重要的应用。管道设计图纸通常很复杂而且必须符合精确的工业规格。
其他优处
CAD/CAM也能在其他方面影响一个公司的工程系统。它能提高整个物理过程的效率，允许现行工程方案和报告程序的评估。CAD/CAM能改善提高品质保证技术。它能自动准确与完整的文件资料，保持部分数据的准确和材料表的准确。
不足之处
CAD/CAM的不足点不那么明显，但它们能破坏甚至最完善的设计，最大的缺点是仅能直接从手工制图与记录保存跳转到CAD/CAM，就像把一套喷气式发动机安装到大众汽车内。汽车可能会跑得快一些，但如果底座没有增强去配合重压，整部汽车就会散架。
CAD/CAM的应用
SKETCHPAD、CAD/CAM技术已走过了很长的踟。它已经被应用于各种广泛的工业当中。它　用于各个方面，从飞机控制到武器研究，从地图制作到运动医疗，从电路分析到建筑钢材分析。CAD/CAM正被应用于各种制图和生产中，从电影装置的草图到大型远程监控直接集合战舰，它的应用正向多方面发展。
当今CAD/CAM市场.
当今市场上有四种不同的CAD/CAM卖主。首先是一些附属公司销售来自大企业一个部分或分支的CAD/CAM技术。IBM的CAD/CAM分支就是一例。如属于Mc-Donnell-Douglas的McAuto;属于General Electric的Lalma,和属于Schlumberger的Applican，多大数的CAD/CAM附属公司与其总公司有大量的业务往来，不但销售监控系统而且人微言轻服务办事处。当他们控制大量帐且和提供服务时，这些公司就在最佳状态，因为他们可以从中抽取大量的利润。但他们必须承担复杂的行政系统，这有碍于他们对市场趋势作出快速的反应，或他们自己本身研究及开发部门外，合并再改进他们新的生产线上新技术的开发。
