本文简述了传统正交三轴座标系DDA插补器后引出了用于一般多座标联动数控系统的“模拟空间直线”DDA插补原理,并在此基础上介绍了一种软—硬件相结合的DDA插补器。
This paper briefly introduces the principle of “analog space linear” DDA interpolation used in general multi-coordinate linked numerical control system after the traditional orthogonal triaxial coordinate system DDA interpolator, and on the basis introduces a soft- Hardware combined with DDA interpolator.
