3. Computer
Aided Design
(CAD)
• CAD involves creating computer
models defined by geometrical
parameters.
• These models typically appear on a
computer monitor as a three-
dimensional representation of a part
or a system of parts.
• CAD is the technology that helps
designers to view their Product, or
Model, under various
configurations.
• These can be readily altered by
changing relevant parameters.
• Common CAD Softwares :
AutoCAD, Draft Sight, Solid Edge,
Solid Works, CATIA, Fusion 360
etc.

4. CAD systems enable designers to
view objects under a wide variety
of representations and to test
these objects by simulating real-
world conditions.

Design

6. Computer Aided
Maufacturing
(CAM)
• Technology that
gives data and
command to the
Automated
Machinery as per
the geometrical
data, associated
with computer
numerical control
(CNC) or direct
numerical control
(DNC) systems.

7. CAD/CAM
CAD and CAM both use
Geometric data and computer-
based methods. So
simultaneous work can be
performed from process
designing to developing. By
creating a model using CAD,
and encode that model with
CAM and Manufacturing it as
per the model. Hence
Computer-Aided Design
(CAD) and Computer-Aided
Manufacturing (CAM) are
commonly used as
CAD/CAM Technology.
