1. Introduc
ction to
CAD/ CAM & CIM

2. CAD: It can be defined as the use of computer
systems to assist in the creation, modification,
y e , ,
analysis or optimisation of a design
CAM: It can be defined as the use of computer
systems to plan, manage and control the
y p , g
operations of a manufacturing plant through
direct or indirect compputer interface with the
p
plants production resour
rces

3. A CIM architecture is an information systems
structure that enables industrial enterprises
s
integrate information and business processes It
d
accomplishes this first by establishing the direction
integration will take; and second, by defining the
interfaces between the us sers and the providers of
this integration function

36. The B i
Th Basics
Computer graphics: genera ating 2D images of a 3D
world represented in a comp
puter.
Main tasks:
modeling: (shape) creating an representing the geometry
nd
of objects in the 3D world
rendering: (light, perspective) generating 2D images of the
objects
animation: (movement) describing how objects change in
time
