孔径圆度自动测量及数据处理

Automatic Measurement and Data Processing of Roundness of Hole

传统的圆度检测手段存在效率低、设备投资大和互换性差等不同缺点。已有的自动检测装置要求测量装置中心与被测件圆心必须重合。针对上述问题提出基于计算机和传感器技术的圆度自动检测系统的设计。在检测装置中心与被测件圆心不重合时,利用软件根据检测数据计算被测孔圆心坐标,进而实现对孔圆度的计算,速度快,精度高。

Traditional pensively and interchangeab measuring methods of roundness have any weakness that the efficiency lowly, equipments exility badly etc. Many of the automatic measuring device require that the central of measuring de- vice coincidence with the central of circle we measured , Because of these problems now gives an automatic measuring system based on computer and sensor. When the central of measuring device doesn＇t coincidence with the central of circle we measured we need use computer software to calculation the center coordinates and roundness automatically ,quickly ,accurately.
