数控仿形系统中的数字化技术

Digitizing Technique in CNC Copy Milling System

利用仿形仪扫描模型表面，自动生成描述模型表面的数控指令，实时转存到软磁 盘中。利用上述的数字化结果在数控功能支持下进行数字化加工，可以加工出各轴独 立改变比例的工件和镜像的工件，也可以实现阴阳模工件的配对加工。数字化技术在 模具及复杂表面加工中有童要意义。

By means of a tracer to scan a model the part program describing the model in detail is automatically produced. These digitizing data are stored on floppy disks and can be used to conduct digitizing machilling under the func- tion of CNC. work parts with independent scale factor on each axis, mirror imaging and 'male' corresponding 'female' can be made.
