CpK: a point of proof
Imagine if you could take precision machined parts, directly from the box and know that each part you pick up is of an equal, calibrated standard quality, moving you ever closer to a consistent >CpK*=1.33 “same in every way” supply.
*CpK = Process Capability Index
CpK refers to a statistical tool used in manufacturing to measure how well a process can produce output within a specified tolerance range.
It helps:
- identify process improvements for increased efficiency and quality
- act as a proof point to assess a process’s abilty to consistently produce components within defined limits, taking into account both process variability and how close the process is to the target value.
A CpK value above 1 indicates a process is likely capable of meeting the specifications.
We calculate etching allowances for each and every component to help achieve optimum CpK values. This minimises variation across the blank and across the production run. We work with customers requiring 1.33 and above and we constantly strive to reach a value of 2.0.
the importance of metrology
When you’re dealing with precision parts with features measured in microns for pioneering -and often critical- applications like we do, even the most microscopic deviation from the specified design can affect performance.
Metrology is at the heart of what we do. It provides a proof point of the precision we achieve and establishes a foundation of truth that we can feed back to our wider team and our customers.
Our dedicated team has a deep technological understanding of metrology and uses all the resources available to them to provide a valuable feedback loop both back to our inhouse engineering professionals and the customer. In this way, we can make sure – and prove – that the results we produce are aligned to the original specification and requirement.
Development in the field of metrology is advancing at speed. We are able to achieve continuous improvement due to this feedback loop. This robust process gives the Tecan Business insights to help us feed back quantifiably and qualitatively to our customers at a micro and sub-micro scale, measured in micrometres.
