Renewal made of the mould , advanced high - speed machining center , with the high rotational speed , so high as to enter for the speed , high precision and high efficiency to replace profile modelling to mill , namely process and replace simulation to process with the data , from the three - dimensional data mould three - dimensional structure numerical control cnc form of the products , all appear with the data 模具制造的更新，先进的高速加工中心，以高的转速高的进给速度高的精度和高的效率取代了仿形铣，即以数据加工取代模拟加工，从产品的三维数据模具三维结构数控cnc程式，全部以数据显现。
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
In the thesis , the general situation of the domestic and abroad developments in the field of the numerical control interpolation algorithm for aspheric surface machining is reviewed firstly , for the poorness of recent numerical control interpolation algorithm , an numerical control interpolation algorithm that based on the genetic algorithm ( ga ) and neural network ( nn ) is introduced 在数控系统中,它是生成加工轨迹的一个最基本的子程序,在很大程度上决定了数控机床的加工精度和最大进给速度。本文首先综述了国内外非球曲面超精密加工中所运用的插补算法的发展概况。
This text explicate the content , structure and function of post processing , analysis to compare the special post processing system ' s procedural structure and operational process with the general post processing system ' s . questions the post processing procedure ' s key problem - the algorithm principle of post processing ; it studies the three - axis ' s machining , the cutter location computation of multi - axis ' s and the feed rate of multi - axis ' s running . studies and compares the general cutter location files " form of cad / cam systems 本文介绍了后置处理技术的内容、结构与功能，分析比较了专用后置处理系统和通用后置处理系统的程序结构和操作流程，探讨了后置处理程序中关键问题? ?后置处理的算法原理，对三坐标加工和多坐标加工的刀位计算以及多轴联动加工的进给速度进行了研究。
For instance : nowadays use the small and exquisite paint - spray robot abroad , can scan the size of specification of the work piece and programme by oneself automatically , whole craft circulation go on in succession , according to accurate to is it stock give speed to control procedure have , all parameters of spraying paint in the angle and distance etc . , use the painting amount to obviously reduce 如：当今在国外使用小巧的喷漆机器人，能自动扫描工件的规格尺寸并自编程序，整个工艺循环连续进行，按程序精确控制进给速度喷漆角度和距离等所有参数，用漆量明显减少。
