机床数控装置基准脉冲插补原理研究

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。

Research of CNC Devices Benchmark Pulse Interpolate Principle

Benchmark pulse interpolate,interpolation ended only at a time,to the moving axis output control pulse,each coordinate only in increments of one pulse equivalent or travel.Pulse sequence frequency represents the coordinate movement speed,and number of pulses representing the motion displacement size.Interpolation principle is also called track control theory,principle and interpolation based on interpolation operations research helps us to better master the processing technology,has a certain amount of theoretical and practical implications.
