Recent Developments in Garment Manufacturing
· CAD/CAM:
CAD and CAM are two technologies that have made prominent changes in the way garment manufacturing was done in previous eras. Today all large garment manufacturing companies have developed CAD/CAM system to do the process of garment manufacturing.
CAD is an abbreviation for computer-aided design and CAM for computer-aided machine. CAD/CAM is computer software that controls the production of garments.
In CAD the designer designs the garments by using any suitable software like Adobe Photoshop, Adobe Illustrator, Corel Draw etc and in CAM the cutters, sewers, graders and markers control the process of development.
The designer creates 2-D or 3-D model of design in CAD and CAM as a software numerically controls the machines that generates the production.
There are several advantages of CAD/CAM over manual method of designing and production of garments:
The expense and time is reduced in a considerable manner when compared to the laborious manual work of designing.

Translation is a transformation that repositions and object along a straight line path from one coordinate location to another. … Read more »
Rotation of an object is repositioning it along a circular path in the xy plane.To rotate, we need to specify a rotation angle θ and the rotation point(xr,yr) about which the object is rotated. … Read more »
