Measurement process capability / solara.MP


The evaluation of machines, production facilities and current manufacturing processes is based on the statistical analysis of characteristic values. Processes measuring predefined characteristics provide these values. In order to avoid misinterpretations, the recorded measured values have to be reliable reflecting the real conditions, i.e. measurement processes have to be capable of performing the demanded task in the respective situation. solara.MP is the perfect choice to establish measurement process capability.

Measurement system capability according to MSA

Type-2 study

Suitable measurement processes are required to achieve beneficial results. The MSA (Measurement Systems Analysis) reference manual often provides the basis for this decision. solara.MP is the tool of choice for instrument and gauge capability.

solara.MP conducts necessary capability studies to establish measurement system capability. The main differences between generally accepted studies such as type-1 (Cg/Cgk), type-2 and type-3 studies (%GRR) or linearity and stability analyses are the applied calculation methods and the respective limit values. The software encompasses the procedures given in the MSA manual of the AIAG Core Tools and many other guidelines of the automotive industry.

Capability analysis according to VDA 5

VDA 5 measurement uncertainty budget

Measurement processes are affected by a variety of influence quantities. Many standards thus demand the calculation of measurement uncertainty. VDA Volume 5 offers a practical approach and solara.MP helps to implement it easily and intuitively.

The calculation of measurement uncertainty is based on an approach that is quite as pragmatical as a MSA capability analysis; however, it follows the specifications of GUM (Guide to the expression of uncertainty in measurement) or EN V 13005. solara.MP thus combines uncertainty components into an uncertainty budget and calculates the expanded measurement uncertainty U.

Measurement uncertainty according to GUM

Expanded measurement uncertainty

While the “Guide to the Expression of Uncertainty in Measurement (GUM)” explains the theoretical backgrounds of the calculation of expanded measurement uncertainty, solara.MP actually creates an uncertainty model for every inspection process for immediate visualization. solara.MP will display the relationship between the uncertainty components in a clear flow chart with each box representing an uncertainty component. These uncertainty components can be edited with a mouse click. The combined standard uncertainty and the expanded uncertainty is calculated based on input of an intuitive logical operation formula.


Type-1 study

Regardless of the methods you use and whether you conduct capability analyses at a test station, production line or in a test laboratory, solara.MP makes sure to provide you with the most reliable and actionable information you need!
