What is ICT???
Stands for "Information and Communication
Technologies."
ICT refers to technologies that provide access to
information through communications. It is similar
to Information Technology (IT), but focuses
primarily on communication technologies. This
includes the Internet, wireless networks, cell phones,
and other communication mediums.

What is CAD???
Computer-aided design (CAD) is the use of computer systems to
assist in the creation, modification, analysis, or optimization of
a design.
CAD software is used to
✓increase the productivity of the designer,
✓improve the quality of design,
✓improve communications through documentation, and
✓to create a database for manufacturing.
CAD output is often in the form of electronic files for print,
machining, or other manufacturing operations.
7
CAD
❑CAD is used to create or modify designs. The final design can then
be digitally printed, or the information sent directly to cutting
machines.
❑Here, pattern pieces are designed on the computer and then
printed.
8
What is CAM???
Computer-aided manufacturing (CAM) is the use of
computer software to control machine tools and related
machinery in the manufacturing of work pieces/products.
CAM may also refer to the use of a computer to assist in
all operations of a manufacturing plant, including
planning, management, transportation and storage.
Its primary purpose is to create a faster production process
and components and tooling with more precise
dimensions and material consistency, which in some
cases, uses only the required amount of raw material
(thus minimizing waste), while simultaneously reducing
energy consumption.

CAM in industry
Transfer printing
An image is produced using CAD (Computer
Aided Design) and printed out onto the
transfer paper.
This image is then ironed face down onto the
fabric.
When it is cool you are able to remove the
backing paper.
There are many different papers on the
market – some require reversing.
10
CAM in Apparel industry
Embroidery machine
1. A design is copied using a scanner
or created using CAD software.
2. The embroidery machine can be
linked directly to a PC or designs
can be transferred on a disk.
3. The image is then downloaded onto the machine’s memory
and output onto the machine bed, creating a machined logo or
image.
11
CIM
❖ Computer-Integrated Manufacturing (CIM) systems
integrate or link CAD and CAM systems.
❖ These combined systems link design development, production
planning and manufacturing systems together.
❖ Companies that use CIM are able to design a product in one
country and manufacture it overseas where labour costs are
lower.

INTRODUCTION OF CAD
CAD means Computer Aided Design that is a project assisted by
a computer. CAD is the use of computer technology to aid in
the design of a product.
• CAD actually encompasses all those activities of product
design cycle with converts a workable concept into a ready to
manufacture product specifications. The various sections are:
13
CAD tool Elements
1. Geometrical Modelling and Computer
Graphics: Helps in generation and visualizing
models on which the analysis is done
subsequently.
2. Analysis and Optimization tool: It predicts the
behaviour of the model under the loading
conditions when all constraints are simulated
using boundary conditions.
3. Drafting and Documentation tool
14
CAD Software
CAD software is used to increase the productivity of the
designer, improve the quality of design, improve
communications through documentation, and to create a
database for manufacturing.
Auto CAD: Explore and visualise 2D/3D concepts with a powerful
set of intuitive design tools.
Real CAD Pro: It is all purpose 2D/3D CAD software for full 3D
modelling, rendering, and 2D drafting in one inexpensive
solution.
Rhino3D: It is the best tool for opening, editing, fixing and
converting 3D files of almost any type, as well as being a brilliant
3D modeller in its own right.
15
CAD Software
• Iron CAD: It is the productivity leader when it
comes to moving creative ideas into full 3D
reality.
• PRISM: It allows the editing of shades of colours
on the printer and makes a calibration according
to the original colour & colour on the screen.
• COLOUR TEX: It creates realistic simulation of
fabric created in colour weave. It is possible to
create a wide variety of yarns of all material and
types.
16
CAD Software
• MODARIS: Garment Sector
• TUKACAD (TUKATECH): Garment Sector
• LECTRA: Used in garment sector mostly for pattern
making, Grading and designing.
• REACH CAD (REACH TECHNOLOGY INDIA): Garment
Sector
• OPTITEX PDS (pattern design system) - Garment
Sector
• AUDACES APPAREL (VELCO GARMENT MACHINERY,
S.AMERICA): Garment Sector
• GT RESOURCES: Garment Sector
17
VARIOUS TYPES OF CAD SYSTEMS
• Currently, the following are the different types of CAD
systems available in the market for the use of garment
industry.
i. Digitizing systems
ii. Grading systems
iii. Marker making systems
iv. Pattern design software (PDS)
v. Pattern generation software (PGS)
vi. Body measurement software
vii. Texture mapping
viii. Embroidery systems
ix. Specification & costing systems
18
COMPUTER AIDED MANUFACTURING
(CAM)
• CAM is the use of computer software to
control machine tools and related machinery
in the manufacturing of work pieces.
19
CAM Tools
1. CAD Tool: Geometric information of model
2. Manufacturing Tool: Fundamental of
manufacturing processes
3. Networking Tool: Communication between
various machines and computers

COMPUTERIZED EMBROIDERY
MANUFACTURE (CEM)
✓ Embroidery can be applied directly to piece goods and
continuous fabrics.
✓ The design philosophy for the embroidery CAD / CAM
system was developed on the basis of an engineering
CAD/CAM.
✓ It is appropriate to call the system as CED/ CEM (Computer
Embroidery Design/Computer Embroidery Manufacture).
✓ CED is a multi user, multi-taking computer graphics system
for the design of embroidery patterns.
✓ CEM machine coding and the online electronic control of
embroidery machines represent the embroidery pattern.
21
CAD / CAM IN INDUSTRY
CAD/CAM system have greatly influenced in all
kind of industries, but perhaps its effort can
be appreciated more by those industries
which used to invest a lot in prototype
building and testing.
Basic conceptual model which can be used in
Mechanical Industry are:
22
23
ADVANTAGES OF CAD
i. Allows to shorten the time elapsing between the development of the
new fashion ideas and the collection presentation
ii. CAD reduce staff requirement in a given work as complex
engineering drawing can be easily done by use of CAD
iii. Quicker preparation of the collections
iv. The degree of repetitiveness in the design part is more with the
help of CAD
v. The number of prototypes or samples to be physically produced
prior to acceptance by the customer is greatly reduced by use of
CAD system, thus resulting in cost and timesaving.
vi. CAD system provides Quick Response (QR) capabilities to an
enterprise by compressing the “design
- manufacturing - marketing" cycle time.
24
ADVANTAGES OF CAD
vii. Cad system produce more logical pattern & improve
concentration of designer to give optimum design
viii. Lower interference with the production activity.
ix. CAD system can easily interface with CAM devices
x. (Computer Aided Manufacturing) for machine control
& Fabric production becomes practically automatic.
xi. It gives fewer design error
xii. CAD system gives greater accuracy in design
calculation
25
ADVANTAGES OF CAD
xiii. The Designs can be stored in libraries, can
be recalled, modified, and evaluated quickly
xiv. The CAD systems can directly download
process information (e.g. machine settings,
lifting plan) to the shop floor; designs can be
quickly brought to production of woven fabric.
xv. Continuous monitoring & the control on the
whole production cycle.
xvi. Offer a better service to the customer
26
Advantages of computerization in
-Garment Section
❖Computerized interactive marker making by CAD system.
❖Very accurate, efficient cutting & spreading of fabric.
❖Different automatic like auto trimming, speed control, auto
thread cutting mechanism of sewing machinery.
❖Auto display of process data of the sewing m/c like model
