Abstract
This disclosure provides a method and system for measurement system analysis (MSA) that present a structured and effective way of performing an MSA. The MSA system and method involves determination of a category of MSA for a measurement system based on an application of the measurement system, a quantification of measurement variation, calculation of a decision rule value based on the quantified measurement variation and a decision rule associated with the determined category, a determination of whether the measurement system is capable of performing MSA for the category based on a comparison of the calculated decision rule value and a decision rule threshold value, and applying a measurement system determined as capable for performing MSA to manage.
Claims7
A method for measurement system analysis (MSA), comprising:
- determining, using a processor, a category of MSA from a plurality of MSA categories for a measurement system, each MSA category corresponding to a different application of the measurement system, and having a different decision rule associated therewith stored in a memory accessible by the processor;
- determining, using a processor, a type of the MSA based on a source of measurement variation for the measurement system;
- quantifying, using the processor, the measurement variation based on the determination of the type of the MSA;
- calculating, using the processor, a decision rule value based on the quantified measurement variation and the decision rule associated with the determined category of MSA;
- determining, using the processor, whether the measurement system is capable for performing MSA for the category based on a comparison of the calculated decision rule value and a first decision rule threshold value;
- and
- when it is determined that the measurement system is capable for performing MSA for the category, applying the measurement system to manage a quality of a manufacturing process or assist in a definition of product design.
A system for measurement system analysis (MSA), comprising:
- a category determining module configured to determine a category of MSA from a plurality of MSA categories for a measurement system, each MSA category corresponding to a different application of the measurement system, and haying a different decision rule associated therewith stored in a memory accessible by the category determining module;
- a MSA measurement variation quantifying module configured to determine a type of the MSA based on an identified source of measurement variation for the measurement system and to quantify the identified source of measurement variation based on the determination of the type of the MSA;
- a decision rule value calculation module configured to calculate a decision rule value based on the quantified measurement variation and the decision rule associated with the determined category of MSA;
- a capability determination module configured to determine whether the measurement system is capable for performing MSA for the category based on a comparison of the calculated decision rule value and a decision rule threshold value;
- and
- a controller configured to apply a measurement system determined as capable for performing MSA to manage a quality of a manufacturing process or assist in a definition of product design.
