如何有效地使用的CAD/CAM(题目黑体3号)

(字体宋体小四,行距固定值23磅,英文也一样)在美国软件的使用已成为生活的一部分。不同的企业对CAD/CAM的要求各不相同,因此许多企业认为通过定制自己的系统以满足他们的特殊需要是并不奇怪的。定制的企业有时要花费一年时间去完成这个任务。考虑到这一点,工程师怎么设计和企业如何有效地使用的CAD/CAM设计模具和零件以及企业如何有效地开展工作?当这些变得似乎是显而易见的时候,许多公司就会对这些工具和功能印象深刻,以至于软件开发商扔给他们甚至有时会忘记他们需要什么。为了使设计工程师能充分利用CAD/CAM设计模具或零件,有四个关键内容必须具备:

1通过软件的维护和定期的硬件更新使硬件和软件工具保持最新,从而确保兼容所有的设备。

2对使用他们软件产品公司。设计者必须提供全面和持续的培训,使公司通过设备和人员将会获得以最大的效益。

3为了制造工程师能在使用方法、程序设计和需求上简单易懂,设计工程师必须制定一个清楚的说明和解释

4企业选择的CAD/CAM系统必须完成某项工作。这应包括演示自己的部分,因为如果你的机器不能正常运行,就算是最强大的系统的最佳功能也是无用。大多数买家,除非他们在以前的系统遇到过这类问题,否则他们往往会忽视这非常重要的一点。对模具设计者来说这可能是昂贵的和费时的,所以,买家可要小心了。

保罗戴克是专门为办公设计软件的产品经理,在Alias/Wavefront(多伦多,安大略省)一个2-D/3-D图形技术供应商,他说“设计工程师必须清楚的知道这些,他们必须是多学科,能够跨越国界,在同一时间成为专家和通才。团队合作技巧已成为关键,而唯一的途径是公司提供合适的工具帮助工程师在这个蓬勃世界成长。”

CAD和CAM软件数据间的转换的应用是非常高的。在欧洲IGES的标准格式和流行的德国汽车工业协会的标准被软件开发者开发,以满足他们的数据库结构。当选择一个系统满足您的生产需要时,请确保该系统提供了一个灵活的IGES 的支持,可以进行工作通过使用公司的现有的软件或在不久的将来可以购买的软

件。

大多数制造商希望扩大它们的业务,使他们能够提供更多的服务给客户,并且获得新的客户。他们还可能会带来更多精密机械去减少模具/零件的制造成本。考虑到这一点,选择CAD/CAM的系统将伴随你的公司一起成长。

从这里可以看出高速加工机械可以节省时间和金钱,甚至在那些旧机器中也可以。例如,如果您正计划购买一台4轴或5轴联动的加工中心,你必须确保可以升级您的软件以支持这些机床的运行。

另外在进行模具或零件的工作演示时,你必须在今天内完成,以确保公司所选择的CAD/CAM系统可让你实现长期目标和带来最小的阻碍。查看供应商提供升级的路径以审查以前的软件系统。

那些共同特点-或附加应用程序-可选用成本项目轨迹核查,后处理器,制定后处理器的发展和通讯工具。找出如果升级到一个新的水平的软件系统,供应商的政策是什么,并得到书面的说明。

“从一个公司到另一个公司所给的模具或零件的要求大部分是建立许多因素之上,”查尔马修斯,DP科技公司(一个CAM系统的开发商)市场副总裁说到。“如公司的设计标准,制造过程中被使用或行业服务的公司-同一部分用于航空航天和医疗公司可能需要完全不同的设计要求是建立在为业界提供服务的政府规章里“

计算机辅助设计的能力:

在大多数公司里计算机辅助设计的能力还没有得到充分利用,这是和CAD 运营商技术和经验水平有关的。CAD运营商平均技术和经验水平的增加,公司将从CAD中得到更多的利益。另外,CAD软件公司可以改进那些易用性的软件,以减少技能或经验水平的需要,从而最大限度地受益。

George Bousted,Dassault Systemes公司(一个全球软件开发的的CAD,CAM,CAE和产品生命周期管理的市场)的汽车业务部门的技术经理,说他还没有看到任何一家公司-大的还是小的-即使接近充分利用一个CAD系统的能力,更不用说一系列集成的软件系统。

大公司把各种团队的人叫来一起定义“新”的做事方法,而这些团队的人并不通常都有那些工程和必要的技能去确定产品设计系统。越大的公司,你将会有更少的机会去发现工程师们实际负责的东西。小公司没有足够的技术去利用一个

CAD系统所提供所有的能力,也没有时间学习所有的或那些购买和实施的资源。然而,工作在较小公司的人通常有较大的广度去理解,因为他们要涉及许多领域。

在世界上一个好的设计工程师不会提供的所有工具和产品,然而,设计工程师需要在坐下来创造一个模具或零件之前知道如何使用这些工具。硬件,软件和数据库不会去做设计-而工程师去做。

“在过去一位CEO可以步行通过一个设计工作室,并知道他的工程师们在设计什么;看到蓝图和设计草图粘满了所有的墙壁,”Bousted说,“现在,一切都储存电脑的主机里,这意味着该公司的人必须知道的文件在哪里,最重要的是知道如何工作,而这只有工程师自己才知道。

How to Effectively Use CAD/CAM

Software has become a fact of life in American manufacturing.CAD/CAM requirements differ among companies,so it''s not surprising that many find it necessary to customize their systems to meet their particular needs.A company''s customization may sometimes take up to one year to complete.With this in mind, what do design engineers and their companies need to effectively use CAD/CAM to make molds and parts and what do companies need to have in place for them to do their work effectively?While this may seem obvious to some,many companies become so impressed by the gadgets and features that software developers throw at them that they sometimes forget what they need.In order for design engineers to fully use CAD/CAM to make molds or parts,four key elements need to be in place:

1.The hardware and software tools should be kept up-to-date through a software

maintenance contract and regular hardware updates,thereby assuring compatibility of all of the equipment involved.

2.The designers must be provided with comprehensive and ongoing training on the

software products they use in order to maximize the benefits that the company will receive from its equipment and people.

3.The design engineer must develop a clear understanding and compassion for the methods,process and needs of the manufacturing engineers.

4.The CAD/CAM system that a company chooses must perform the job it is advertised to perform.This should include a demonstration on your own parts because the most powerful systems with the best features are useless if they won''t run your machine properly.Most buyers,unless they have experienced problems with previous systems,tend to overlook this very important point.This can be costly and time-consuming a moldmaker-so let the buyer beware.

"Design engineers simply have to know more these days,"says Paul Dyke, product manager for Studio Tools at Alias/Wavefront,Inc.(Toronto,Ontario)-a 2-D/3-D graphics technology provider."They have to be multi-disciplined,they have

to be able to cross boundaries and be specialists and generalists at the same time. Teamwork skills have become critical and the only way companies can help engineers thrive in this new world of engineering is to supply them with the right tools." Software Needs Checklist

Data translation between CAD and CAM software applications is very high on the list of problems for buyers.The standard format IGES and the popular VDA in Europe are often flavored by software developers to fit their database structures. When choosing a system to fit your manufacturing needs,make sure that the system provides a flexible IGES support that can be customized to work with your company''s existing software or software you may be purchasing in the near future.

Most manufacturers hope to expand their operations so that they can offer more services to

customers and gain additional customers.They also may bring in more sophisticated machinery to decrease mold/parts manufacturing costs.With this in mind,choose CAD/CAM systems that will grow with your company.

Among the things to look for is high-speed machining that can save time and money even on your older machines.For example,if you are planning to add a four-or five-axis machining center,make sure that you can upgrade your software to support these operations.

In addition to being able to perform the mold/parts work that you need done today, make sure that your company''s chosen CAD/CAM system allows you to achieve your longer-term goals with minimum difficulties.Check to see that vendors provide upgrade paths that take into consideration your previous software systems.

The common features-or add-on applications-that can be optional cost items are toolpath verification,post processors,custom post processor development and communication utilities.Find out from the vendor what its policy is for upgrading to the next level of its software system,and get it in writing.

"The requirements for a given mold/part can vary greatly from company to company based on many factors,"says Chuck Matthews,VP of marketing for DP Technology,Inc.(Camarillo,CA)-a CAM system developer."Such as a company''s

design standards,the manufacturing process to be used or the industry the company is serving-the same part designed for aerospace or medical companies may require completely different design requirements based on the government regulations for the industry being served."

The Power of CAD

The power of CAD has not been fully utilized by most companies,which is associated with the skill and experience level of the CAD operators.As the average operator''s skill and experience levels increase,companies will be able to increase the benefits they receive from CAD.Alternately,CAD software companies can improve the ease-of-use of their software to reduce the skill/experience levels required to maximize the benefits received.

George Bousted,automotive business unit technical manager for Dassault Systemes of America(Troy,MI),a global software developer for the CAD,CAM, CAE and product life management markets,says that he has not seen any company-large or small-even come close to fully utilizing the power of a CAD system,let alone a series of integrated software systems.

Large companies put together teams of people to define"new"ways of doing things and these teams aren''t usually made up of people who have the engineering and requisite skills to define product-engineering systems.The bigger the company, the less chance you will find engineers actually in charge of something.Small companies don''t have the technical breadth to utilize all of the capabilities that a CAD system provides,nor do they have the time to learn all of it or the resources to purchase and implement it.However,the people working in smaller companies typically have a larger breadth of understanding because they have to wear multiple hats.

Being supplied with all of the tools and gadgets in the world does not a good design engineer make;however,design engineers need to know how to use the tools before sitting down and creating a mold/part.The hardware,software and databases do not do the designs-the engineers do.A big misconception out there is that you can train people to use CAD/CAM,when in reality engineers have to be pretty proficient

already-it''s the idea in the engineer''s head that gives life to the various CAD/CAM gadgets.

"A CEO in the past could walk through a design studio and know what his engineers were designing;seeing blueprints and design sketches pinned up all over the walls,catching glimpses of models sitting out on their desks,"says Bousted. "Nowadays,everything is stored in the depths of the computer''s mainframe,which means those in the company have to know where the file is and,most importantly, know how to bring up the work.Only the engineer can access it."

Inventory management Inventory Control On the so-called "inventory control", many people will interpret it as a "storage management", which is actually a big distortion. The traditional narrow view, mainly for warehouse inventory control of materials for inventory, data processing, storage, distribution, etc., through the implementation of anti-corrosion, temperature and humidity control means, to make the custody of the physical inventory to maintain optimum purposes. This is just a form of inventory control, or can be defined as the physical inventory control. How, then, from a broad perspective to understand inventory control? Inventory control should be related to the company's financial and operational objectives, in particular operating cash flow by optimizing the entire demand and supply chain management processes (DSCM), a reasonable set of ERP control strategy, and supported by appropriate information processing tools, tools to achieved in ensuring the timely delivery of the premise, as far as possible to reduce inventory levels, reducing inventory and obsolescence, the risk of devaluation. In this sense, the physical inventory control to achieve financial goals is just a means to control the entire inventory or just a necessary part; from the perspective of organizational functions, physical inventory control, warehouse management is mainly the responsibility of The broad inventory control is the demand and supply chain management, and the whole company's responsibility. Why until now many people's understanding of inventory control, limited physical inventory control? The following two reasons can not be ignored: First, our enterprises do not attach importance to inventory control. Especially those who benefit relatively good business, as long as there is money on the few people to consider the problem of inventory turnover. Inventory control is simply interpreted as warehouse management, unless the time to spend money, it may have been to see the inventory problem, and see the results are often very simple procurement to buy more, or did not do warehouse departments . Second, ERP misleading. Invoicing software is simple audacity to call it ERP, companies on their so-called ERP can reduce the number of inventory, inventory control, seems to rely on their small software can get.

Shifts in the economy, globalization, domestic diversity, and technology have created new demands for organizations, and propelled the field in some completely new directions. However, we believe that these challenges also create numerous opportunities for HR and organizations as a whole. Thus, the primary purposes of this article are to examine some of the challenges and opportunities that should influence the future of HR. We also consider implications for future research and practice in the field. Keywords: Future of human resource management, Globalization, Knowledge economy Diversity, Technology 1.Change from a manufacturing to a service or knowledge economy One of the major challenges influencing the future of HR processes is the change from a manufacturing to a service or knowledgebased economy. This new economy is characterized by a decline in manufacturing and a growth in service or knowledge as the core of the economic base. A service economy can be defined as a system based on buying and selling of services or providing something for others (Oxford

And more importantly, if followed some of the principles of good design, it can be said of separating and content to create high-quality, reusable, easy to maintain and modify the application. For example, if the document in HTML embedded Java code too much (script), will lead the developed application is extremely complex, difficult to read, it is not easy reuse, but also for future maintenance and modification will also cause difficulties. In fact, CSDN the JSP / Servlet forum, can often see some questions, the code is very long, can logic is not very clear, a large number of HTML and Java code mixed together. This is the random development of the defects. Early dynamic pages mainly CGI (Common Gateway Interface, public Gateway Interface) technology, you can use different languages of the CGI programs, such as VB, C / C + + or Delphi, and so on. Though the technology of CGI is developed and powerful, because of difficulties in programming, and low efficiency, modify complex shortcomings, it is gradually being replaced by the trend. Of all the new technology, JSP / Servlet with more efficient and easy to program, more powerful, more secure and has a good portability, they have been many people believe that the future is the most dynamic site of the future development of technology. Similar to CGI, Servlet support request / response model.

Project Budget Monitor and Control Author:Yin Guo-li Nationality:American Derivation:Management Science and Engineering.Montreal: Mar 20, 2010 . With the marketing competitiveness growing, it is more and more critical in budget control of each project. This paper discusses that in the construction phase, how can a project manager be successful in budget control. There are many methods discussed in this paper, it reveals that to be successful, the project manager must concern all this methods. 1. INTRODUCTION The survey shows that most projects encounter cost over-runs (Williams Ackermann, Eden, 2002,pl92). According to Wright (1997)'s research, a good rule of thumb is to add a minimum of 50% to the first estimate of the budget (Gardiner and Stewart, 1998, p251). It indicates that project is very complex and full of challenge. Many unexpected issues will lead the project cost over-runs. Therefore, many technologies and methods are developed for successful monitoring and control to lead the project to success. In this article, we will discuss in the construction phase, how can a project manager to be successful budget control. 2. THE CONCEPT AND THE PURPOSE OF PROJECT CONTROL AND MONITOR Erel and Raz (2000) state that the project control cycle consists of measuring the status of the project, comparing to the plan, analysis of the deviations, and implementing any appropriate corrective actions. When a project reach the construction phase, monitor and control is critical to deliver the project success. Project monitoring exists to establish the need to take corrective action, whilst there is still time to take action. Through monitoring the activities, the project team can analyze the deviations and decide what to do and actually do it. The purpose of monitor and control is to support the implementation of corrective actions, ensure projects stay on target or get project back on target once it has gone off target。

JSP外文文献原稿和译文

外文文献原稿和译文 原稿 JSP JSP (JavaServer Pages) is initiated by Sun Microsystems, Inc., with many companies to participate in the establishment of a dynamic web page technical standards. JSP technology somewhat similar to ASP technology, it is in the traditional HTML web page document (*. htm, *. html) to insert the Java programming paragraph (Scriptlet) and JSP tag (tag), thus JSP documents (*. jsp). Using JSP development of the Web application is cross-platform that can run on Linux, is also available for other operating systems. JSP technology to use the Java programming language prepared by the category of XML tags and scriptlets, to produce dynamic pages package processing logic. Page also visit by tags and scriptlets exist in the services side of the resources of logic. JSP page logic and web page design and display separation, support reusable component-based design, Web-based application development is rapid and easy. Web server in the face of visits JSP page request, the first implementation of the procedures of, and then together with the results of the implementation of JSP documents in HTML code with the return to the customer. Insert the Java programming operation of the database can be re-oriented websites, in order to achieve the establishment of dynamic pages needed to function. JSP and Java Servlet, is in the implementation of the server, usually returned to the client is an HTML text, as long as the client browser will be able to visit. JSP pages from HTML code and Java code embedded in one of the components. The server was in the pages of client requests after the Java code and then will generate the HTML pages to return to the client browser. Java Servlet JSP is the technical foundation and large-scale Web application development needs of Java Servlet and JSP support to
