MSA - Dealing with inherent within-part variation in assemblies

Registered
I am currently working on methods to account for within part variation which is unavoidable in testing some assemblies. This may be due to break-in, lubrication, thermal effects, or just plain 'nature of the beast'. As anyone familiar with MSA knows, w/in part variation will present as measurement system variation. if anyone else has ways of mitigating, or have any ideas, looking to hear from you.

Can you provide more detail on the product? The methods will be very application specific. I understand the general issue that you are describing as I have encountered it numerous time when testing complex electro-mechanical devices. However, the solution varied depending on the product and characteristic. The generic solution is to substitute a simple surrogate for the complex product. This might be the substitution of a spring with similar force characteristics to the product. The actual solution will depend on the product and characteristic.
