为改造现有计量设备,扩大微机应用范围,以提高旧设备的功能和效率,因此我们将上海机床厂生产的HYQ-14型圆度仪配置微机采集和数据处理系统,采用12位A/D转换器.并用最小二乘圆法和最小区域圆法评定圆度误差值,圆度误差的图形可以在屏幕上显示,也可以用四色的绘图机绘制.求最小区域圆法的圆心我们探索了一种较简便的、搜索速度较快的、精度较高的方法,在一般微机上512个采样点求圆度误差仅1～2分钟左右.经用2.3μm圆度的样板在仪器上实测结果为2.3±0.16μm,说明系统是良好的.
In order to transform the existing measuring equipment and expand the range of microcomputer applications to improve the functions and efficiency of the old equipment, we have configured the HYQ-14 roundness meter manufactured by Shanghai Machine Tool Plant to be equipped with a microcomputer acquisition and data processing system. The 12-bit A / D Converter and the least square method and the minimum area circle method to assess the value of roundness error, circularity error graph can be displayed on the screen, you can also use four-color plotter draw. A more convenient, faster search, high precision method, 512 points in the general computer on the roundness error of only about 1 to 2 minutes by 2.3μm roundness of the model measured on the instrument The result was 2.3 ± 0.16 μm, indicating that the system is good.
