Measurement Systems Analysis (MSA) evaluates measurement systems in manufacturing, focusing on errors like repeatability (variability from the same operator) and reproducibility (variability from different operators). Gage R&R Analysis, using the A&R or ANOVA methods, quantifies these errors to ensure manufacturing processes meet customer requirements.

Gage management provides manufacturers with data to ascertain the quality of their parts.

For most processes, we have a choice of measurement options that vary with cost. Ideally, we seek the most accurate measurement at the lowest cost with the expectation that the result will be satisfactory. When measurements are critical to operations, we should validate these assumptions.

If you’re looking for more data in less time, 3D scanning may be a good choice for your application.

The obvious reasons for automating quality in manufacturing are to reduce scrap, rework, overtime and costs while simultaneously increasing productivity and customer satisfaction. The non-obvious reasons include employee satisfaction, customer referrals and market growth. Automation also give managers and line workers insights into ongoing production. 

True or false: Measuring products, unlike other processes, is not subject to variation.

Discovering the underlying factors that influence compliance, product quality, production efficiency and your performance as a supplier requires greater accuracy and precision than many manufacturing metrics provide.

The first step to process improvement is machine performance measurement and diagnosis. However, it’s a step that many OEMs and service providers—even quality professionals—fail to approach with as much rigor as other steps, like process setting and in-process control. 

The process of analyzing gage variability is often highly structured, involving an examination of the gages themselves for sensitivity to temperature changes, magnetic fields, and other factors. These are the easy ones. The second area of variability has its source in gage operators themselves, who may have different levels of training, experience, fatigue, and even attitude.
