Multicriterial Optimization Applied for Choosing the Measuring Instrument
Journal Title: RECENT - Year 2012, Vol 13, Issue 36
Abstract
According to David C. Crosby, "If you don’t know the capability of your measurement system, you don’t know if your measurements, or your products, are good or bad". Starting from this basic it had been made an comparative analyze from the point of view of the capability of measuring of an interior diameter micrometer, indicating micrometer (caliper) and a 3D measuring machine in order to identify the optimal management measure for serial machining pieces to measure interior diameters. The test was made in a controlled environment, with different operators in order to see how each measuring system is affected by the variables: method of work and operator. The performance characteristics used to determine which measurement device is the best choice to be used in serial production were: cost of the system, quality, measurement system analyze or repeatability and reproducibility (R&R), efficiency and method of measurement for each device. From the case study made, the result was that the best cost effective, with the best efficiency, in quality and with the best MSA (Measurement system analysis) value is the caliper.
