80年代末,我国开始应用计算机控制圆度仪技术,经10年的发展,已研制出全电脑化的电气系统,并投入批量生产,性能也有很大提高,增加了3种评定方法、谐波分析等功能。但系统响应较慢,不能实时显示被测工件的轮廓,测量过程较长。 以某型号圆度仪为例,分析其系统(如图1)得知, In the late 1980s, China began to use computer-controlled roundness meter technology, after 10 years of development, has developed a fully computerized electrical system, and put into mass production, performance has greatly improved, an increase of three kinds of assessment methods, harmonics Analysis and other functions. However, the system response is slow, can not be real-time display of the contour of the measured workpiece, the measurement process is longer. To a model roundness meter, for example, analyze its system (Figure 1) that,
