The function of the software use pc - computer to dispose the output signal which is produced by the device as following steps : ( 1 ) to input data by parallel interface ( 2 ) to record and form a file ( 3 ) to demonstrate results step by step ( 4 ) the results could be compiled ( 5 ) it can synthesis in the permitted error scope , substituted original dot for line or arc , finally we could get a graph that is described by some simply curve . ( 6 ) to convert these graph into a program , which used in the cutting process of numerical control . ( 7 ) the software also includes some protective methods 而系统处理软件的作用是：利用pc兼容机，将上述装置的输出信号( 1 )通过并行口输入( 2 )记录成文件( 3 )逐点显示出来( 4 )可人工进行化简，编辑(删、改点)等( 5 )可在给定误差范围内进行人工拟合，用直线和圆弧取代原来的点，得到一个与原图形的误差在规定范围内，又消除跟踪过程中因受到各种干扰而造成的缺陷，由尽可能少而简捷的数学曲线描述的图形( 6 )把这些图形转化成用于编制数控线切割加工程序及autocad能够识别的文件(主要指dxf格式) ( 7 )该软件还有一定的加密措施。
