The Technial Rearsh About The Application Of The Leather Fabric Cutting CAD/CAM System

As an important field of garment industry, the leather fabric apparel manufacturing industry is highly reviewed.Its products cover leather, footwear, luggage, furniture, and more involved in transport vehicles, luxury cruise ships and other interior decoration. With the leather products widely used in various fields, the leather products industry deepens the degree of automation corresponds to the increasingly high demand. Now,United States, Japan, Canada and other developed countries, are being developing and popularizing the automated leather cutting system.The existence of irregular shape and defects on the large format natural leather, determines the leather’s processing, from nesting to cut manual labor, both to increase the labor intensity and hinder leather products production and there quality improvement. In order to improve the automation level of production of the leather processing industry, this subject researches the computer vision system for the leather fabric edge extraction and defect check, the technical applications of the garment CAD software, the leather fabric layout optimization theory and the CAM technology based on the laser cutting equipment, etc. And by the experimental analysis the theoretical research and review about the leather fabric cutting CAD/CAM applications technology are carried out based on image processing on digital photographyAs a subsystem of the large rapidly responding garment system, the main researched topic contains the building method of the computer vision system, the calibration of the internal and external camera parameters based on the HALCON image processing, the leather fabric contour extraction and defect Edge mark, and the leather fabric nesting and layout optimization with the AUTOCAD. Initially building up the leather fabric cutting CAD/CAM applications technology system which is to be able to communicate the HALCON visual image proceeding software and the driver software of the laser cutting machine around the core AUTOCAD software, achieves the tentative plan of the integrated automatic leather process.The application technology of this CAD/CAM system in the cutting process, which is the generally single costumes cutting system category, includes the large sheet of leather leather edge recognition, defects Edge extraction, the CAD layout, the CAM cutting. It Involves the optical, mechanical, digital image processing, computer control and other disciplines. For a large number of domestic leather production enterprises, especially SMEs, the subject of research could provide an effective solution for the production and processing of natural leather products,Although the main studied object of the topics is the natural leather fabric, but the results can be applied to other large-format and irregularly-shaped sheet metal cutting and the layout processing so as to support the applied trademarks, clothing accessories, ornaments and other fabrics on the complex cutting pattern.
