摘要
The knitting industry CAD/CAM system's development needs a solution of computer representation of the designed objects.One of them is a transformation of knitting rows and stitches form knitting pattern and its automatic analysis is to control data from the knitting design data.A method of the pattern CAD system including the analyzing and the compiling of the pattern data was developed in this paper.By rasterizing the pattern map,the drafted pattern could be compiled into knitting row data and stitches.The storage format of knitting rows data and stitches data could be defined by analyzing the motion of computerized fiat knitting machine.By reassembling the control data,it could be analyzed into the execute data of the controller in computerized flat knitting machine.This method mainly focused on the weak areas of multi-needle-bed technology and fully-fashioned knitting technology in inland and could be applied to most of control systems in the master-slave mode.The knitting row data and pattern row data in a " *.ptn" format file were integrated.Giving a corresponding analytic calculation process of control data and realizing independent development of the upper machine and the lower machine,the final knitting control data not only have low computation and transmission cost but also have fast transfer speeds.
