The study has given the following problems and solved as

follow:

1. CAD/CAM’s role in making forms/shapes.

• In high technological form product making technology, informative technology is

applied effectively and play a decisive role in Mechatronics – a new mechanics in

the 21

century.

• Applying informative technology in forming mechanics by numerical controlling

device has scientific and practical meaning in training as well as in practice of

producing mechanics.

2. CAD/CAM technology and data base serving CAD/CAM process.

• Organizing to build data base serving technological prepared process has scientific

and practical meaning in training as well as in practice of producing mechanics.

• The maths of building data base serving CAD/CAM process is a difficult and

complex, therefore the content of the thesis is limited in researching the organizing

drawing-feature data base in order to fit the building the data base of the

componets with an aim of reducing the designing time to bring the objectives to the

machining.

3. Choosing data base drawing-feature form.

• To make the building the data base drawing-feature possible, it is needed to base on

the data base towards the objectives is the most suitable form for organizing the

data base CAD/CAM.

• On the base of choosing CATIA data as the data base towards the most suitable

objectives for the drawing-feature data base having searched the features of CATIA

data base in order to carry out the research for building drawing-feature data base

as well as for implemeting it in practice.

4. Organizing data base in making forms/shapes.

• Built data base for designing precess an applying form of plastic product.

• Building data base for the main parts in plastic product’d form.

5. Applying the piont of view of data base to form machining object.

• Applying the point of view of data base for designing form for plastic product is the

cover of the mobile phone.

• Using WinCam software for designing and machining process for some kinks of

forms/shapes.

Key Word: CAD/CAM’s role in making forms/shapes; CAD/CAM technology and data

base serving CAD/CAM process; Choosing the shape for drawing-feature data base;

Organizing data base for making forms/shapes; Applying data base point of view in

establishing machining objectives.
