早稻田大学理工学部的中泽研究室,研制出一种测量系统,采用主动测量方式,检测切削过程中产生的高频振动.这一系统的原理是:用微音器将切削中的噪声放大,再用微型计算机来解析其信号的周期分量,从而检测出高频振动的发生情况.这个系统的结构如图所示.图中予处理回路,是将微青器测出的噪声信号用AC 放大器放大,只把正的部分输入A/D 转换器.振荡电路产生规定A/D 转换器转换周期的定时脉冲。从而决定数据进行A/D 转换时的读数间隔.A/D 转换器将通过予
Waseda University Department of Science and Engineering, Nakazawa Laboratory, developed a measurement system, the use of active measurement methods to detect the cutting process of high-frequency vibration.The principle of this system is: with a microphone to amplify the noise in the cutting, And then use the microcomputer to analyze the periodic components of the signal to detect the occurrence of high-frequency vibration.The structure of this system as shown in Figure pretreatment circuit is the noise signal measured by the micro-green with AC amplifier Amplification, only the positive part of the input A / D converter. Oscillation circuit to generate the specified A / D converter conversion cycle timing pulse. Thus decides the data to read the interval when A / D changes.A / D converter will pass
