CAD Technology Status Of Apparel In The World

Garment CAD plays an important role in alleviating the bottlenecks in the process of industrialized mass production of garments, namely, garment process design, that is, the computer operation of pushing and discharging, not only improving production efficiency, but also greatly improving production conditions and environment.

In 1970s, Asian textile and apparel products hit the western market. The textile and garment industry in western countries, in order to get rid of the crisis, promoted the development and development of garment CAD under the development of computer technology.

As a modern high-tech design tool, CAD technology is the combination of computer technology and traditional garment industry.

The United States has developed the first MARCON clothing CAD system. In succession, the US Gerber company has put the clothing CAD onto the market, which has aroused a good response in the field of CAD, and has led to the development of many other companies in the field of clothing CAD.

GGT, Lectra and Investronic in Spain have also launched their own clothing CAD systems.

The 3 companies have formed a tripartite trend in the field of international garment CAD/CAM.

At present, besides the products of the above 3 companies, the clothing CAD/CAM system in foreign countries mainly includes American SGI, Germany's Assyst, Japan's Toray, Juki, Nissyo, Switzerland's Alexis and so on.

At that time, clothing CAD played an important role in alleviating the bottleneck in the process of industrialized mass production of garments, namely, garment process design, that is, computer operation of pushing and discharging, not only improving production efficiency, but also greatly improving production conditions and environment.

(1) American Gerber company in the early 1980s, the Gerber clothing AM-5 CAD system of the US company, with HP minicomputer as the main engine, and the input rules of the code in the way of "fixed point" reading, converting the geometric switch and related information of the board into the data acceptable to the computer, storing it in the computer database, managing it, and doing the material disposal on the computer screen, and then making the accurate cutting through the computer automatic cutting system.

Another clothing CAD system of Gerber company is Accumark based on IBM PC. It represents the development direction of the new generation of clothing CAD system.

The system adopts a microcomputer workstation structure, which is used to communicate with each other through high-speed Ethernet. The server with hundreds of MB to thousands of MB capacity is used as the information storage and management center. The automatic cutting machine, unit production system, management information system and other CAD/CAM systems are connected through the network to form a computer integrated production system CIMS.

2. The 301+ / 303+ system of French Rick, France's French company, combines the concept creation of clothing with the design of plate, board and layout.

Its latest system OPEN CAD system has the characteristics of modular and open. It contains 5 basic systems, namely, M100, M200, X400, X400G+ and X600S system. Users can choose according to speed, capacity, display, memory and other requirements.

The module includes functional modules developed by Rick and CAD/CAM online operation system.

Recently, the French company launched OPEN CAD open module software, not only within the company's own system, but also its system can be compatible with the non gram system.

(3) the outstanding features of the clothing system of Spanish Inves company Inves (Weiss) are manifested in the application of advanced technologies such as artificial intelligence and robotics.

The T-CAR pport robot developed by robotics is a highly automated, customer-oriented garment production system from the customers' selection of styles, fabrics, measurements of customers' body shape, automatic sample design, code placement, automatic discharge, automatic single chip cutting machine and unit production system to high speed and high quality. It is a highly automated customer-oriented garment production system. It proposes a new batch production method which is different from traditional batch production mode, and develops an integrated system of cost management, sewing and storage management, namely clothing CIM.

(4) other CAD / CAM systems, based on the principle of computer vision, developed the apparel design system of American Technotailors and second Skin Swimmear with contactless human body measurement system.

He designed a three-dimensional human body model, so as to establish a corresponding sample design system for the Japanese Dongli company.

The application of a large capacity optical disk storage system has adopted a more graphic and easy to understand graphic menu interface technology for Japanese Shima Selkl clothing design system.

He has an animation system that can be used to reflect the effects of clothing in three dimensional fashion design. It can simulate the fashion design system of the Swiss model of University of Geneva and Swiss Confederation Institute of technology.

The style design system of French Lectra company without mouse and keyboard is directly painted.

To adopt the decentralized processing mode of basic information of computers is the clothing design system of Japanese heavy machinery industry, which is systematized and networked in different locations.

It can simulate the three dimensional drape effect of different fabrics and generate garment wear effect diagram in real time to achieve 360.

Rotate the 3D fashion design system of the US Computer Deign Inc. company from different sides.
