According to these goals, the product design mus

The advantage obtained by using some modules from different CAD-CAM-CAE software is to use the most performant parts of these software (specific to the engineering fields)

5、 at a low price (it isnt necessary all the software, only some specific modules). The internet 3D on-line catalogs offer the advantage to find very easy useful information about mechanical elements (prices, technical characteristics, 3D models, etc,). Key words: CAD-CAM-CAE software, internet on-lin

The manufactures have to deal with the increasing demands of the customers. They have to improve continu

To become more competitive into a world with diversity of p

8、roducts, with continuous changes, the companies must modernize and increase the flexibility of the production systems. The companies find out that the interactive design of a product is the most efficiently tool for analysis end evaluation. So the use of internet data base and CAD-CAM-CAE software c

On the market there is a lot of CAD-CAM-CAE software which offer specific tools for engineering design into a tri dimensional

By using them it can be created a 3D virtual product, simulate from many point of view 1, in order to improve its characteristics (te

Some of these softwares have better performances for some engineering fields as aeronautics, automotives, mechanical etc. Today single CAD-CAM-CAE software cannot cover the entire industrial field for high performances. Another major disadvantage of that softwares is very

12、high prices for a full version. Usual the prices are starting from several thousands of EUR. There are 3 advantages for the most CAD-CAM-CAE softwares: 1 - the softwares are structured in modules, even in the same area (for example: in CATIA in mechanical design are: part design； sheet metal design,

13、 mold design, wierframe and surfaces design etc)； 2 - it can be bought only some specific package regarding computer aided design, computer aided manufacturing or computer aided engineering； 3 - all these software allow to save date in some commune file format (for example: dxf for 2D drawings, step for 3D solids； iges for 3D surfaces etc). These types of files can be opened by almost all CAD-CAM-CAE software in some specific condition Fig.1 Specific modules in the same domains Fig.2.Gear - dxf format Fig.3 Gear- Catia format Fig.4.Gear - step format Fig.5.
