Background technology
Clothes beat version and refer to Size calculation result according to key position in clothes automatically, are automatically drawn with computer
Go out the domain of basic clothes style, and the result drawn is consistent with actual hand-drawing result.Clothes is beaten platemaking technology and existed automatically
It is of crucial importance in garment manufacturing industry, because it can greatly reduce beating the version time for plate-making teacher, improve clothing efficiency, enhancing enterprise
The competitiveness of industry.
Clothing plate making technology is broadly divided into two classes:
The first kind:Plane cutting method:Plane cutting refers to the data calculated according to formula, and experience of plate-making teacher etc.,
Apparel construction figure is drawn on the paper of plane, forms pattern tissue, then single-piece is carried out using pattern or batch is cut, make life
Production.Plane cutting is not directly perceived enough, relies on experience, is not suitable for completing the complicated three-dimensional clothes style with pleat.Such as day basis
Type is cut, Chinese proportional cutting, and parent form cuts and belongs to plane cutting;
Second class:Three-dimensional cutting method:Three-dimensional cutting refers to first use fabric (fabric of the low suitable designed concept of cost)
The style molding operation of clothes is come out (fabric fixation on people's platform by pin) on stereo man table, with pen on fabric
Carry out the mark of apparel construction line;Then the structure lines that fabric repaiies suitable garment piece in the plane are removed;Finally the clothes knot of fabric
Structure line, which is copied on paper, forms pattern tissue completion plate-making.Three-dimensional cutting is directly perceived, independent of experience, is adapted to having for completion complexity more
The strong clothes fashion of the third dimension of pleat.
Although three-dimensional cutting method can complete more complicated clothes fashion, this method carries stronger people's industry and traffic
Interoperability is, it is necessary to which cutter's rich experience, the rule unobvious during cutting, special active computer simulate this mistake
When journey, it is difficult to which the isometric Horizon of fabric model is taped against in plane, then mistake will be introduced when cutting the structure lines of garment piece
Difference, cause final domain unavailable.Then for plane cutting method, because it is operated in paper pattern, technical staff
Skill is ripe, and manufacturing process is regular follows, and is especially suitable for computer simulation.
But existing plate-making CAD software merely provides the instrument of plane cutting, it is necessary to which Shi Benshen wirings of making a plate, are formed
