interpolation controls
Examples
- It is important for us to choice the method of interpolation . which is key for the cnc system
插补控制算法的选用，是cnc系统的关键之处。 - On the basis of analyzing the theory of software and hardware , the two level interpolation in cnc apparatus , this paper analyzes the possibility of software fine interpolation . then it gives an example of cnc system which using software fine interpolation
在分析了当今广泛用于cnc装置的软、硬件两级插补控制机理的基础上,对用软件实现精插补控制的可行性进行了分析,并进行了试验验证 - A control method is presented where least square arc approximation and timed interpolation are employed . using it , the number of segments of fitted curves is made minimum while the accuracy is guaranteed , so that data transmission between cad and cnc systems is decreased and setted feeding rate can be realized . this method has already success fully been used for flame cutting and controlling saddle - backed curve for pipe connection when feeding rate is required to be higher
提出了一种采用最小二乘法圆弧逼近及定时插补控制方法，在保证精度的前提下，可使拟合圆弧段数最少，从而减少cad系统与cnc系统的数据传送，可实现给定进给速度.该方法已成功地应用于要求较高进给速度的接管马鞍型曲线火焰切割拟合控制 - 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。
