CAD Section

Introduction:

                In jeans care Ltd. Auto CAD (Computer Aided Design) is an important section. Here all the consumption is done. With the measurement of the different parts of a garment by the help of CAD system software pattern & marker can cut or make. Here with the combination of the parts of a garment efficient marker can make for cutting purpose. By creating grading from one size different size can create by the software.

CAD System Software: Two systems are available

1. Lectra System, made in France
2. Garber System, made in USA

Machines in CAD section:

Purpose                      Machine Name                         Quantity

Marker make               Garber plotter (Width=72 inch)          1

                                       Alotex (Width=82 inch)                      1

Process Sequence: CAD section

Pattern for a specific garment

or manually sketch the different parts in the computer

                                               ↓                                                         

Keep those separately on digitizer board (for pattern) 

                                                                                                        ↓

With the help of sensor system input the actual measurement of those parts

                                                                                                        ↓

Resize and give a shape for marker

                                                                                                        ↓

                                                                        Grading
                                                                                                        ↓

Efficient format for making the marker

                                                                                                        ↓

Make marker with the help of Lectra or Garber system

Efficiency Measure:                            Total placed area  * 100%            

Formula: Total marker efficiency =   _____________________

                  Length * Diameter

Efficiency (usually get)

For Tank top       - 75%

For trouser         - 78%

For t shirt             - 85%

For polo shirt     - 85%

N.B.: If a garment consist smaller parts then there efficiency is higher than the larger parts of a garment.
