Error Compensation on Probe Parameters of Articulated Arm CMM

Abstract

Abstract. The error compensations on probe parameters were proposed to improve the measurement accuracy of an articulated arm coordinate measuring machines (AACMM). An AACMM's probe parameters were analyzed and a measurement model including probe parameters solely was built. A simple cone socket components were used as a calibration tool and the LM algorithm was edited to solve the probe parameters. The results show that the average measurement error dealt with the probe parameters recalibration is 0.044mm, and its standard deviation is 0.050mm. They have increased by about 31% and 33% than those without recalibration.

Analysis and Compensation of Equivalent Diameter Error of Articulated Arm Coordinate Measuring Machine

“…The method combining dynamic calibration of probe radius and micro plane compensation was put forward to make compensation for the probe radius. 5 Zheng et al 6 improved the measurement efficiency and accuracy of the probe using a simple cone socket component, a calibration tool, and the Levenberg–Marquardt (LM) algorithm, which was edited to solve the probe parameters. Huang et al 7 proposed a new three-dimensional (3D) resonant trigger probe based on a quartz tuning fork to achieve true 3D nano-measurement with sub-nanometer resolution and very low touch force through a micro/nano-CMM.…”
