Abstract

Double Parallel Joints coordinate measuring machine (CMM) is a new type coordinate measuring device with 9 structural parameters with accuracy difficult to be ensured just by processing and assembly. Calibration is needed to identify the structural parameters of the measuring machine. This article describes the calibration process of such a Double Parallel Joints CMM, and simulation was employed to analyze how the number of samples and angle measurement accuracy influence the measurement precision and calibration result during calibrating process. The conclusions are very instructive to precision design or error allocation and calibration process of the Double Parallel Joints CMM.
