Cost-Efficient Measurement System Analysis for Small-Batch Production

Abstract

This paper presents an approach for the selection of methods for the proof of capability of measurement processes according to the risk connected to a false decision. High risks demand more reliable and therefore cost-intensive methods, a low risk allowing for cost-efficient methods with lower reliability. This approach, which is incorporated into the upcoming guideline VDI/VDE 2600-1, allows manufacturers to reduce efforts and costs associated with measurement process evaluation according to the risks and consequences of erroneous decisions deriving from measurement results. To be able to decide for the economically optimal measurement process solution, a cost model for the processes described in the VDI/VDE 2600-1 is presented.

Virtual indoor-GPS for measurement uncertainty determination in reconfigurable environments

“…1 iGPS configuration with three transmitters and a receiver Fig. 2 Virtual measurements within optimization of reconfigurable assembly systems assembly tolerances enables an estimation of the process capability [39]. If the determined process capability value meets the requirements, a feasible configuration is found enabling capable measurement processes, whereas an insufficient value leads to another optimization cycle.…”
