Research on Calibration Technology of Volumetric Errors for Coordinate Measuring Machine Based on Improved Double Ball Bar

Abstract

三坐标测量机作为一种高效便捷的新型精密测量设备,现已广泛应用于机械、汽车、航空航天以及电子工业等现代精密制造业中。为了满足大尺寸、复杂曲面零部件的检测需要,对三坐标测量机的整体测量精度提出了更高的要求和挑战,如何快速高效地提升三坐标测量机的整体测量精度是亟待解决的问题,而通过误差标定是提升三坐标测量机测量精度的一种有效途径。通常针对三坐标测量机测量精度的标定仪器主要有:激光干涉仪、激光跟踪仪和球杆仪。由于激光干涉仪和激光跟踪仪分别存在测量繁琐、测量成本高及测量周期长等不足,而传统球杆仪也存在测量功能单一、测量范围受限等问题,因此本文创新性地提出了基于传统球杆仪与圆光栅融合的新型测量装置,并根据...Coordinate measuring machine as a highly efficient and convenient new precision measuring equipment, nowadays has been widely used in machinery, automotive, aerospace, electronics industry and other modern precision manufacturing industry. In order to meet the large size and complex surface parts of the detection needs, the higher requirements and challenges of the whole measurement accuracy of co...学位:工学硕士院系专业:航空航天学院_机械制造及其自动化学号:1992014115287
