3. INTRODUCTION
 Today in competitive world, it is difficult to run with
the speed of the market, without implementation of
the new technologies in Industrial world.
 The whole world is coming closer due to the regular
advancement in technology.
 CAD/CAM/CAE for tool engineering is now become
an essential part to keep pace with growing
technology and demand for low cost, quality,
precision & faster delivery.

4. METHODS
 CAD/CAM (Computer added design and manufacturing)
 CAPP (computer added process planning)
 CAI (computer added inspection)
 2D drawing To 3D modeling
 3D model to 2D drawing
 Rapid prototyping
 NC data generation
 Rapid prototyping
 Concurrent engineering

5. ADVANTAGES
 Shorter Design Lead time
 Reduced die trials
 Automatic Gating Feature creation
 Optimizes runner and gate weight, resulting in improved yield
 Automatic Runner and Overflows creation
 Reduction in rejection rates due to better filling of casting
 Automatic calculation, systematic editing & built- in
intelligence Shorter lead times - Die development

6. DISADVANTAGES
 Casting weight must be between 30 grams (1 oz) and 10 kg (20
lb).
 Casting must be smaller than 600 mm (24 in.).
 High initial cost.
 Limited to high-fluidity metals.
 A certain amount of porosity is common.
 Thickest section should be less than 13 mm (0.5 in.).
 A large production volume is needed to make this an
economical alternative to other processes
