Research on Calibration Methods of Volumetric Motion Errors for Large Scale Coordinate Measuring Machine

Abstract

三坐标测量机作为工业零部件的主要检测设备,具有通用性强、自动化程度 高、测量精度高等特点,被广泛应用于工业制造及科研技术开发领域。随着制造 技术的发展,零部件朝着大尺寸,复杂面形,高精度等方向发展,这使得大行程 三坐标测量机不可或缺,同时也对大行程三坐标测量机的检测精度提出了更高的 参数要求。然而,目前大行程三坐标测量机的误差标定仪器主要是激光干涉仪和 激光跟踪仪,它们在标定过程中存在使用成本高、测量周期长、需配专用调试人 员等不足,无法得到广泛应用。鉴于此,本文创新性地提出了一种基于球杆仪循 环联动误差测量实现三坐标测量机局部空间误差识别与补偿的方法,并通过拼接 数据处理将球...Three coordinate measuring machines (CMMs) are known as main detection equipment for industrial parts with the characteristics of good universality, high automaticity, high precision and so on.
