Measurement System Analysis: How Companies Ensure Precise Results

• Measurement System Analysis (MSA) checks the reliability and accuracy of measurement systems
• Used in industries such as mechanical engineering, automotive, aerospace, and medical technology
• Focus on methods like Gage R&R, bias studies, and ANOVA
• Influencing factors: equipment, operator, environment, material
• Optimization through calibration, training, and digitalization

Measurement System Analysis (MSA) forms the foundation for stable and traceable measurement results in industrial manufacturing. Companies use this method to secure production processes and meet product quality requirements. In the manufacturing environment, MSA ensures that measurement results remain reproducible and traceable, and that measurement technology meets the ever-increasing demands of the market.

Measurement System Analysis (MSA) refers to the systematic evaluation of measurement systems regarding their performance and reliability. It differs from a full measurement process analysis, as it focuses specifically on the measurement device used rather than the entire process.

The development of MSA is closely linked to increasing automation and rising quality requirements over the past decades. Today, it is an integral part of standard quality assurance and certification processes, especially in the manufacturing industry.

The purpose of a Measurement System Analysis (MSA) is to ensure the reliability and accuracy of measurement data. It examines whether a measurement system delivers the required precision and whether results are consistent across different operators. This allows both systematic and random errors to be identified and avoided. Consistent application of MSA reduces costs by lowering scrap rates and complies with standards such as ISO 9001, IATF 16949, and VDA 5.

Key Goals and Benefits:

• Determine the performance capability of measurement systems

• Identify and prevent measurement errors

• Ensure comparability and traceability of measurement results

• Comply with quality standards and regulatory requirements

Measurement system analyses are used across a wide range of industries. In mechanical engineering, they help monitor manufacturing tolerances, while in the automotive and aerospace sectors, they ensure material quality and component precision.

In semiconductor manufacturing and medical technology, MSA is an integral part of quality assurance. The requirements for measurement technology in these fields are particularly high, as even the smallest deviations can lead to significant downstream costs.

The evaluation of a measurement system is based on the criteria of accuracy, repeatability, and reproducibility.

• Accuracy describes the agreement between the measured value and the reference value.

• Repeatability indicates whether a measurement system provides identical results when used multiple times under the same conditions.

• Reproducibility examines whether different operators achieve comparable results using the same measurement system.

All three criteria are essential to ensure error-free data and maintain a stable process.

Various methods are used to evaluate measurement systems:

• Gage R&R Analysis examines repeatability and reproducibility, revealing whether measurement errors originate from the system or the operator.

• ANOVA Analysis identifies systematic deviations in measurement results.

• Bias and Linearity Studies detect and quantify systematic errors.

Additionally, the calculation of Cg and Cgk values provides information on the performance of a measurement system relative to the required tolerance. For qualitative characteristics, attribute-based methods and other analyses are applied as needed.

Various factors influence the results of a measurement system analysis. Device-related deviations arise from the mechanical or electronic characteristics of the measurement system. Human operation can introduce variability if procedures are not standardized.

Environmental conditions, such as temperature or vibrations, affect the stability of the measurement. Variability in materials and components requires precise adaptation of the measurement strategy. All influencing factors are often illustrated using an Ishikawa diagram.

The implementation of a measurement system analysis (MSA) begins with selecting the appropriate method and detailed planning. Once the measurement setup is defined, data is collected through documented measurement series. Analyzing the data identifies sources of error and highlights opportunities for optimization.

The results are documented and serve as a basis for adjustments in production. Software solutions are helpful during implementation, supporting the evaluation and tracking of the measurement system analysis.

Continuous optimization of measurement systems is achieved through regular calibrations and adjustments of measurement strategies. Training personnel ensures reproducible procedures and reduces the influence of individual differences. Integrating measurement system analysis into continuous improvement processes ensures consistently reliable results over the long term.

Optical measurement systems, such as 3D scanners, open up new possibilities for precise analysis of surfaces and structures. White-light interferometry and similar techniques allow the examination of micro- and nanostructures with high accuracy.

Modern systems are highly flexible and can be seamlessly integrated into existing production environments. In practice, these technologies are used to capture complex geometries and to automate quality assurance processes.
