Forty Years of Portable Arm Measurement

In advanced manufacturing settings, portable arms have become a familiar sight, both in inspection areas and shop-floor environments. Their versatility and usefulness have also resulted in their use spreading to a wide variety of settings beyond manufacturing, from clinical measurement in hospitals, to data-archiving of antiquities in museums.

With the passage of 40 years, the range of available arms has proliferated, and specialist arms have developed to improve their suitability for specific applications. Whilst non-contact laser scanning, diverse probing options, wireless connectivity, absolute encoders, and endless software enhancements have transformed the usability of portable arms, their ‘genetic code’ remains remarkably close to that of their early ancestors from the 1980s.

5 Steps to Better Portable Arm Measurement

A popular board game in the 1980s famously took, "a minute to learn... a lifetime to master". Portable arms are a deceptively simple metrology system for which the same catchphrase applies. Arms are designed to be highly flexible and easy to use for a wide variety of measurement tasks. However, understanding measurement datasets and how to use them for verification, reverse engineering or any other application can be far more involved than it first appears. 

Here are five steps to help provide a sound basis for adopting more robust and effective methods when using portable arms. Read more…
