4. Introduction
• CAD and CAM generally stands for Computer aided
Design and Computer aided manufacturing
Respectively. Designing usually starts with CAD
software where actual drawing of the part to be
machined is made which is followed by generating
tool paths on CAM software. CAD Technology =
Design Techniques + Computers The CAD Process is
the subset of the Design process. The CAM Process is
a subset of Manufacturing Process Integration of
CAD and CAM leads to automation.
5. Feathers of CAD CAM
• More than 200 tools and utilities.
• Sophisticated editing tools.
• Any size of design creation.
• Retains all technical details respectively.
• Color palate customization (No limitation for color)
• Yarn layout specification (Warp and weft yarn specification)
Exact alignment.
Fabric simulation.
• No outline gap
• Halftone effect.
• Design card punching output facility (Sari Manufacturing)
• Editing any existing weave. (Dobby, Jacquard, Handloom and Power
loom.)
6. Definition of CAD
• Computer Aided Design (CAD): Is defined as
the application of computer and graphics
software to aid the product design from
conceptualization to documentation.
7. Definition of CAM
• Computer Aided Manufacturing: Is defined as
the effective use of computers in manufacturing
planning and control.
8. CAD Systems for Apparel Industry
• CAD Systems for Apparel Industry Computer
Aided Design (CAD) becomes an essential tool
for pattern making and related jobs in garment
industry. In apparel industry CAD Software is
used for pattern making , Grading of pattern,
marker making and digitizing manual patterns.
There are number of CAD software suppliers
who have developed CAD systems. But only few
names are popular in fashion industry.
9. CAD Systems for Apparel Industry

11. Need for CAD/CAM
• To increase productivity of the designer.
• • To improve quality of the design. •
• To improve communications.
• • To create a manufacturing database.
• • To create and test tool paths and optimize
them.
• • To help in production scheduling and MRP
models.
• • To have effective shop floor control.
12. ADVANTAGES
• CAD/CAM systems allow for rapid development
and modifying of designs and documentation.
• It Lowers the overhead costs.
• The coupling of CAD and CAM considerably
shortens the time needed to bring a new product
to market.
• Increased productivity is generally the
justification for using CAD/CAM system.
• It gives us Error free drafting
