Manufacturing a Carbon Revolution

Manufacturing a Carbon Revolution

There has been huge excitement in recent years about new forms of carbon such as graphene, carbon nanotubes and Buckminsterfullerene (buckyballs). This article looks at the new forms of carbon, such as nanotubes and graphene, and considers whether we may be on the verge of a carbon revolution.

An instrument going from ‘Big Science’ to large-scale manufacturing

An instrument going from ‘Big Science’ to large-scale manufacturing

Frequency Scanning Interferometry (FSI) was invented to measure movements of the detectors in the Large Hadron Collider at CERN. Now a team at the UK’s National Physical Laboratory are developing a practical FSI based instrument for large-scale manufacturing. This may enable the next generation of aircraft with natural laminar flow wings and part-to-part interchangeable assembly.

Sensitivity Coefficients in Uncertainty Budgets

Sensitivity Coefficients in Uncertainty Budgets

This article follows on my previous introductions to uncertainty and uncertainty budgets. It goes into more detail about some of the more tricky aspects of uncertainty budgets. I first explain what sensitivity coefficients are and then use examples to show exactly how sensitivity coefficients can be calculated and used within an uncertainty budget. Read the full article publishedRead more about Sensitivity Coefficients in Uncertainty Budgets[…]

Gage Studies and Gage R&R on engineering.com

If you’ve ever been involved with an industrial measurement process, chances are you’ve come across Gage studies and in particular Gage Repeatability and Reproducibility (Gage R&R). These tests are used to determine the accuracy of measurements. In this article I provide an overview of these studies and how they relate to other methods such as uncertaintyRead more about Gage Studies and Gage R&R on engineering.com[…]

Calculating Your Uncertainty Budget… on engineering.com

Calculating Your Uncertainty Budget… on engineering.com

This is a detailed article explaining how you can calculate an uncertainty budget. It follows my previous introduction to Metrology and Quality in Manufacturing. My previous article introduced the idea that all measurements have uncertainty. This uncertainty stems from different sources, including repeatability, calibration and the environment. To find the uncertainty of a measurement result, weRead more about Calculating Your Uncertainty Budget… on engineering.com[…]

An Introduction to Metrology and Quality in Manufacturing on engineering.com

In this detailed article, I  introduce the basics of maintaining quality. This involves quality assurance, quality control and metrology. We use quality assurance to gain confidence that quality requirements will be fulfilled. Quality control is used to check that requirements have been fulfilled. This is a subtle difference and, in practice, the terms are sometimes usedRead more about An Introduction to Metrology and Quality in Manufacturing on engineering.com[…]
