一、问题的提出近年来采用微机控制的数显技术正被开发和投入使用,如机床刀具的移动尺寸,通过位移传感器(如光栅)将机械位移变成脉冲后送到微机接口电路中,微机进行检测、判断、处理移动后的尺寸,确定加减操作,同予置尺寸比较,将结果以数字形式显示出来。这样就有一个过程,过程就是时间的积累。很显然,这段时间不可大于刀具在最高运行速度时,由传
First, the issue put forward In recent years, the use of computer-controlled digital display technology is being developed and put into use, such as the size of the machine tool movement through the displacement sensor (such as grating) will be mechanical pulse into the microcomputer interface circuit, the microcomputer To detect, determine, handle the size of the move, determine the addition and subtraction operations, with the default size comparison, the results displayed in digital form. So there is a process, the process is the accumulation of time. Obviously, this time can not be greater than the tool at the maximum operating speed, by pass
