A comparison of mechanical artefacts used in calibration of coordinate measuring machines (CMMs)

A Solution to the Accuracy of Multi-Pin Positioning Based on Optimization

“…Due to the over-positioning in multi-pin positioning, there is the possibility of interference among the pins and holes, which may result in failed assembly. Although measuring equipment such as the Coordinate Measuring Machine (CMM) [3] can be employed to obtain the actual positions of holes of part, the measurement of the accumulated errors of assembled parts may not be performed owing to the poor accessibility of measurement. It is also unknown whether the two adjacent parts can be assembled, as well as the positioning accuracy.…”
