Study of the Influence of Measurement Uncertainty on the Sorting of Machined Parts

Abstract:

The basis of effective and efficient production are the measurements. Manufacturing processes should meet the accuracy requirements to produce fit products. Processes capabilities are determined (estimated) and managed by measurements and not at least the suitability of the products are also found by measurements. The measurement technique is considered as a factor associated with costs without taking part in the creation of added value. As a logical consequence is offered to reduce the measurements in order to reduce costs, according to the possibilities, but this leads to increasing of defects in production. This expensive and sometimes fatal consequences of this mentality are not reported. Processes and products are evaluated incorrectly. The number of errors and the expenses increase.
