INTRODUCTION TO CAD CAM

Name: Ashraful AlamID:2014-1-4-069

Available computer

technologies

Examples of computer systems used in the textile and apparel industry include:

Computer Aided Administration (CAA) – computers are used for marketing, sales order processing and stock control.

Computer Aided Design (CAD) – computers are used for developing designs, pattern making, pattern grading, marker production and lay planning.

Computer Aided Manufacture (CAM) – computers are used for store design, lay planning and cutting, sewing and pressing.

Computer Integrated Manufacture (CIM) – a system that uses computers at every stage of planning, design and manufacture.

Electronic Point-of-Sale (EPOS) – a computerised system that speeds up sales transactions and monitors stock levels.

Lets take a close look

of CAD and CAM

CAD ( Computer Aided Design): - to aid the product design from conceptualization to documentation - creation - modification -analysis -optimization CAM (Computer Aided Manufacturing): - planning - manufacturing - control

Looks like • Architectural Engineering

• Civil Engineering

CAD for Apparel industry

•Plotting•Spreading• Cutting•Sewing/Assembling•Surface ornamentation

Software • Let’s take a quick look again what are using now a days • Gerber Technology• Lectra• Optitex• Tukatech• PAD System

Optitex • 1. O/DEV• APPLICATION: • For 2D design and 3D visualization modules in a

single platform to create, tailor and digitize patterns.

• 2. O/PRO• APPLICATION: Contains tools for product

development such as marker making, cut plan and automatic nesting.

• 3. O/SEL• APPLICATION: Used in solutions for sales and

marketing, such as using 3D images for viewing and buying collections.

• The current module is the OPTITEX Digital Collection, an online app to view full 3D collections.

Gerber Technology

OMEGA CP 6.0• Design and production software. It is used

to take design ideas through to high-quality output using cut-vinyl or digital imaging.

• EDGE FXTM

• Thermal Printer for printing designs.ART-Path & Auto-Curve• Used in flatbed cutting system

Lectra and Diamino

•Used in cutting patterns for clothing.•Grading•Used for marker making

YIN CAD • Accurate and efficient digital imaging system

•  can automatically capture all types of pattern contours.

• Automatic generate cutting report, facilitate enterprise effective and convenient management.

• Full intelligent layout systems provide efficient, saving and intelligent layout solution.

More… • By using technology in Apparel Industry we can perform many other important things:– LASER scanning– 3D body scanning– 3D body simulation– Image processing

All these things help to make our product much better.

These things will be clear in the next segment.

VARIOUS USE OF CAD CAM

NazmunnaharID: 2014-1-4-002

3D body scanning

technology

• Leaser Scanning• White light scanning• Image processing scanning• Milimeter-wave rader• Digital tape measurment

Laser scanning

• Leaser to project on to human body one or more thin & sharp stripes simultaneously

• Light sensor acquires the scans & by applying simple geometrical rules the surface of human is measured

• The leaser scanner unit which is composed of the leaser ,the optical system & light sensor is moved across the human body is digitize to surface

White light scanning

• It is the second technology used extremely for human body measurement.

• Ins of moving the scanner unit, a light pattern is projected onto the human body.

• Binary coding are used to determine the origin of the single stripes: for the increment of the resolution ,the projected stripes are additionally shifted.

Digital tape measureme

nt

• The method combines classical human body measurement & digital technology.

• Length are measured by a tape at different key location of the human body like ( chest, waist, sleeve etc.)

Image processing

and modeling

• 3D measurement is not perform but 3D information is generated & extracted from 2D images.

• By using the symmetry of the human body, the most important sizes of body computed with sufficient accuracy from the silhouettes of the body.

• Extremely lower price compared to real 3D measurement.

WHY WE SHOULD USE

CAD CAM?

Name: Md. SobujID: 2014-1-4-005

Are we wasting

our money?

• In our Lab the cost of the installed software in about 10 million.• In the set up of a full industry the cost of the software will be high.

So you can see… • Your production becomes so much

smoother and easy.• Your supply chain becomes more

flexible and it can absorb any sudden change in the production.

• You shipment of product becomes quicker than before.

• You gains buyer trusts for time to time delivery.

• Most of all value of your company Increase.

SO NOW YOU CAN THINK ARE YOU GOING GO WITH

THE MODERN WORLD OR REMAIN BACKDATED ?

THANK YOU VERY MUCH FOR YOUR FULL HELP AND

ATTENTION.
