There are several challenges that can arise when you start the process of measuring micro and meso scale parts. Some important factors to consider before you begin the actual part measuring are: part handling, cleaning, and fixturing. Using a coordinate measuring machine (CMM) allows you to accurately measure extremely tiny parts using touch (tactile) and optical techniques. Carefully following certain steps before you begin the measuring process will help ensure you receive the best possible results upon completion.

Part handling

Unless you have inadvertently dropped a micro or meso part on the carpet, you may not truly appreciate the extremely small scale and accuracy needed to correctly measure them. To use a common analogy; dropping one of these parts could be like “looking for a needle in a haystack” since the size of these parts range from uncomfortably small to nearly impossible to physically handle with your own hand.

It's also important to note that because you are working with extremely small parts, having a clean work area is very important. For those familiar with lean manufacturing, a thorough method for organizing a workplace, especially a shared workplace like a shop floor or an office space, is crucial. You should also be prepared to use gloves to keep dirt, dust, and oil from contaminating the part.
