Measurement System Analysis Aided by New Control Charts

Measurement process must be regularly monitored and evaluated to make accurate decisions about manufacturing process condition or products quality. It is able by statistical methods and tools usage. A paper is a discussion about necessity for measurement systems analysis (MSA) during manufacturing process. There has drawn up a new attitude to MSA which can be characterized by taking the measurements directly from the work position and during the production process. There is also an intention to subject the research results to the readers consideration. Changes proposing by authors will help in eliminating a part of the observed changeability characteristic for the analysis in its so far type, which is laden with the impact of changing environmental conditions during the assessment. What is also significant, that way of data collection limits number of repeats values of first set measurements are from these taken for statistical process control (usage existing data). They propose two new charts for current control Average Difference chart (AD-chart) and %R&R index chart (%R&R-chart). It is important to lead them concurrently (simultaneously) to make correct decisions about measurement system quality condition.
