This document discusses CAD CAM (computer-aided design and computer-aided manufacturing) systems in the textile industry. It begins with an introduction to textile design and manufacturing processes. It then outlines some CAD software used for tasks like marker making and pattern design. CAD CAM modules are used in textile machinery for applications like automatic fabric spreading machines. The cutting room process is also detailed. Key advantages of CAD CAM systems in textiles include reduced lead times and increased productivity through faster spreading speeds. Wastage is also reduced through the use of mathematical algorithms in CAD systems.

3. INTRODUCTION
What is textile Design ???
 A process of creating design for woven ,knitted or printed fiber
 It involved production of those designs, which are used
sometimes repetitively, in clothing and interior decorating items.

9. CAD CAM IN TEXTILE MACHINERY
 Automatic spreading machine
TUKA spreading machine having automatic sharpening knife and raw edges of fabric and
having photo Electric Guides which is used to maintain uniform tension in the fabric
Advantages of spreading machine
Superimpose layers of fabric
Smooth ,tension free surface
Accurate ,efficient cutting

10. CAD CAM IN TEXTILE MACHINERY
Difference between Automatic Spreading machine
And manual
MANUAL
Speed depends on operator
Used by: small firms;
Big firms for small orders
Low productivity
Slower spreading
AUTOMATIC
Can spread 100-150 yards per
minute
Preferred by all firms which
can afford it
High productivity
Faster spreading

12. ADVANTAGES
 Reduce lead time and increase productivity
Two unit of garment industry that is C and M. C unit produces 15,856 pieces per day by using CAD
CAM while M unit produces manually 4,013 pieces per day .
So, the observation results show that cad cam system nearly 10 time faster than manual system.
 Reduction of wastage
Mathematical algorithms built in CAD system
The observation results show10 % fabric saving by using CAD CAM
 Raw edges of fabric do not fray out
