基准脉冲插补,每次插补结束仅向各运动坐标轴输出一个控制脉冲,各坐标仅产生一个脉冲当量或行程的增量。脉冲序列的频率代表坐标运动的速度,而脉冲的数量代表运动位移的大小。基准脉冲插补的方法很多,如逐点比较法、数字积分法、脉冲乘法器等。插补运算的速度和精度是数控装置的重要指标。插补原理也叫轨迹控制原理,根据对插补原理及插补运算的研究,有利于更好地掌握加工技术,具有一定的理论和实际意义。
The reference pulse is interpolated. Only one control pulse is output to each motion coordinate axis at the end of each interpolation, and each coordinate generates only one pulse equivalent or stroke increment. The frequency of the pulse sequence represents the speed of the coordinate motion, and the number of pulses represents the magnitude of the motion displacement. There are many ways of reference pulse interpolation, such as point-by-point comparison method, digital integration method, pulse multiplier and so on. The speed and accuracy of interpolation operation is an important indicator of numerical control devices. Interpolation principle is also called trajectory control principle, according to the interpolation theory and interpolation computing research, is conducive to better grasp of machining technology, has a certain theoretical and practical significance.
