3
CAD/CAM/CAE

• Use of computers to Design, Analyze, and
  Manufacture Mechanical Parts
• Example Autocad
• Basic CAD System
• Use lines to represent the shape of your part
• Patterned after the drawing process
• Example SDRC I-DEAS
• Advanced CAD/CAM/CAE system
• Use Feature Based Solid Modeling to generate
  parts
• Variational or Parametric Modeling

4
CAD/CAM/CAE (cont.)

• Solid Modeling
• Parts are 3-D shapes with Material Side
• Uses features to describe shape
• Block, cylinder, sphere, ..etc.
• Parametric or Variational
• Dimensions and Constraints control the part size
• Changing a Dimension or a Constraint changes the
  part shape
• Feature location is controlled by dimensions

5
CAD/CAM/CAE (cont.)

• Example of parametric modeling

Original Configuration
Change Dimension, the part shape changes. All
other dimensions stay the same.
