1. Several key techniques of carving and milling machine cnc system are deeply studied they include : the transformation , data rebuild and interface design of huge volume nc program produced by cam ; the algorithm of cubic parametric spline pre _ interpolation and high speed real time interpolation in the cnc system , which . will gain a much higher surface precision and cutting speed ; methodology and algorithm of movement velocity acceleration control on a real time forecast _ and _ prejudge basis is designed . therefore , a smooth movement is insured . the shake and noise problem caused by non _ uniform pules for driving stepping or servo motor is solved by an improving algorithm to generate uniform pules
   同时，本文对基于统一的pc平台的雕铣机数控系统中的几项关键技术进行了深入的研究，包括： cam生成加工程序的传送、接收、读取及其加工链表的生成和实时重构；对cam生成的离散数据进行三次参数样条插值和基于累加弦长的三次参数样条插补控制，保证加工工件表面的精度和光顺性；设计具有“前瞻”功能的自动升降速控制方法，保证加工过程的平稳性；通过脉冲均匀化，有效地解决加工过程中因为脉冲不均匀而引起的震动问题。
