【摘要】 目前人们对三坐标测量机动态测量不确定度仍采用静态测量理论来评定,与其实际使用情况不符,带来一定的评定误差。本文在对三坐标测量机测头(Renishaw MH20i)动态误差实测的基础上,采用Monte Carlo方法对测头动态测量不确定度进行评定,与传统的静态测量理论评定结果相比较,本方法评定更符合实际情况。更多还原

【Abstract】 So far dynamic measurement uncertainty evaluation of CMMs is quite limited and the available uncertainty evaluation which based on static measurement theory is not suitable for CMMs using in the real measuring environment. This paper uses Monte Carlo method to evaluate the dynamic measurement accuracy, which is based on dynamic errors testing of probe of CMMs (Renishaw MHI20), Compared with the result of the uncertainty evaluation in static measurement theory, the result of the probe of CMMs dynamic uncertainty evaluation used Monte Carlo method is more suitable for CMMs using in the real measuring environment.更多还原
