摘　要:本文研究了三坐標測量機在高速測量過程中的動態(tài)誤差。以一臺移動橋式三坐標測量機為例，分析了其動態(tài)誤差的產(chǎn)生原因，建立了其動態(tài)誤差的數(shù)學(xué)模型，并對動態(tài)誤差進行了全面的測量和補償。實驗證明，三坐標測量機的動態(tài)誤差具有一定的重復(fù)性，可用軟件補償，從而提高三坐標測量機快速測量的精度。[著者文摘]


Study of Compensation for Dynamic Error of CMM in Process of High-speed MeasuringCui Zhouping Zhu ChenghuaCui Zhouping Zhu ChenghuaAbstract:The dynamic errors of three coordinates measuring machine during fast probing are studied in this paper. Taking a moving bridge CMM as example, its dynamic error sources are analyzed, the mathematic model for dynamic error is established and the dynamic errors are measured and compensated completely. Tbe test results show that the repeatability of dynamic errors is good and it can be compensated by software method to enhance the accuracy of the CMM.[著者文摘]
