Computer Aided Design

It must be analyzed three dimensions: size, degree of automation and integration. The automation on the basis of the man power economy, but the invariability of the automatized process brings more significant profits. The technological choice also must adjusted to the profile of the product. Investments in industrial robotizao have been justified on the basis of its effectiveness and in its efficiency, but, beyond the return on investment and present value of the deducted flow of box, factors as volume flexibility, quality and trustworthiness. CAD? (Computer Aided Design) it can be defined as any activity of project that involves the effective use of the computer to create, to modify or to register an engineering project. The CAD comumente is more comumente associated with an interactive graphical system.

The reasons of System CAD are to increase the productivity of the designer, to improve the quality of the project, to improve the documentation of the project, to create a data base. THE CAD? the geometric modeling works, that is development of a mathematical description of the geometry of the object. The type of mathematical model allows that the user can get an image in the graphical terminal and make operations with the model. It creates new projects of model from available basic modules in the system, to generate and to move the images in the screen, to extend parts you specify in end. The analysis of engineering? after chosen a project, it can be made calculations of tensions, analysis of transference of the heat, calculations of volume, area of surface, determination of the gravity center and simulation. Presentation of the documentation: to quickly prepare the drawings of engineering of high decision. CAM? (Computer Aided Manufacturing) it is defined as effective use of the technology of the computer in the planning, management and control of the production function. The applications of the CAM can thus be divided in two great categories: planning of the production and control of production, which represent two different levels of envolvement of the computer in the operations of manufacture.
