COMPUTERS AND SYSTEMS - CAD CAE CAM CIM

CAD, CAE, CAM and CIM

This paper aims to discuss methods of production advanced on the market, such as CAD, CAE, CAM and CIM.

As a starting point will be considered the current tool for carrying out projects in Computer - the DAC. Within this chapter will be addressing issues related to how the systems design, software and programming available on them.

In the next chapter will be addressed CAE software, which allows, test, simulate and possibly validate a product 3D without having to build physically.

Then we will get to know the machines that allow manufacture parts in quantities and with amazing precision admirable - the numerical control machines. It will be analysed the CAM software, enabling from a design generate a language that understand the machines to perform the pieces. It will be approached to exchange data between the CAD and CAM. At the end of the chapter will be addressed one type of machine also very important - the Robot.

Later will be dealt with the concept and structure of CIM. Presenting an example of its implementation - CIM centre of Porto.

At the end vai be considered the future of equipment and integrated systems.

CAD (Computer Aided Design)

The technical design has been an integral part of the industry since its conception as productive organization, as the technical design is the liaison between the department and production projects.

The design prepared with pre-determined standards makes the information is quickly communicated to the rest of the factory, giving up the product idealized, more quickly. Therefore, the great ally of the evolution of processing power and falling prices of computers, each day increases the number of professionals who use the CAD as a work. But note that the majority of people use only for the development of CAD design, and the power of CAD systems, allows addition of manipulation and integration of information, design projects through representation in three dimensions, allowing various forms of vision and design of projects and reducing the possibility of errors by inconsistencies.

In this chapter, will be addressed systems of existing project, the advantages and disadvantages of using CAD, some areas of application and examples. As the programming in CAD systems, especially in AutoCAD. It will be analysed some of the major programs for CAD, such as AutoCAD & Mechanical Desktop, ProEngineer, the Catia among others. At the end will be presented a case study of programming in Vba in AutoCAD.
