数字程序控制线切割机在生产过程中,有时会遇到加工椭圆的问题。目前,对于椭圆一般是应用折线逼近椭圆的方法来加工的。这种方法的缺点是必须求出大量的坐标点,而且编制程序的工作员也相当大,鉴于这种情况,有关资料根据机械绘图中近似作椭圆的原理,介绍了用 Digital process control line cutting machine in the production process, sometimes encounter the problem of processing oval. At present, for the ellipse is generally used to approximate the oval approach to processing. The disadvantage of this method is that a large number of coordinate points have to be found, and that the number of workers in the preparation of the program is quite large. In view of this situation, the information is based on the principle of approximating an ellipse in mechanical drawing
