Abstract: The main goals to the product development are to obtain a short time of design process, a low

price and best performances of the final product. According to these goals, the product design must use

some modules of advanced CAD-CAM-CAE software and the internet on-line 3D catalogs for some parts

(more or less standard). 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) at a low

price (it isn’t 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-line catalogues, on-line portal 3D catalogues,

standard elements, integrated product design

1.NTRODUCTION

Now, in the industry exists a high competition to produce new, better and cheaper

products. The manufactures have to deal with the increasing demands of the customers.

They have to improve continuously the conception methods of the products, to

modernize the organization structure in order to create a fluent link, without limits,

between studies, design, preparation, manufacturing, commercialization and working life

of the products.

To become more competitive into a world with diversity of products, 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 creates visual data base and industrial geometry design.

Process and product development using computers and internet environment allow a

substantially costs and time economy.

On the market there is a lot of CAD-CAM-CAE software which offer specific

tools for engineering design into a tri dimensional virtual space.

2.USING MULTIPLE CAD-CAM-CAE SOFTWARE

PACKAGES

These kinds of software are representing a very useful tool in products

development design process. By using them it can be created a 3D virtual product,

simulate from many point of view [1], in order to improve its characteristics (technical or

non technical).

Some of these software’s 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

software’s is very 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 software’s: 1 - the

software’s are structured in modules, even in the same area (for example: in CATIA in

mechanical design are: part design; sheet metal design, 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
