VIDEO: 6-Axis CMM Simplifies Measurement and Calibration

Dust-sealed, portable robotic coordinate measuring machine comes with NIST traceable bar.

No-contact tube measurement is developing on point with technological advancements in robotics and related software. The Romer Absolute Arm is one such example.

The 6-axis coordinate measuring machine (CMM) is a portable unit that utilizes beams of infrared light to record data. 

“Whenever I cross over a tube, it automatically takes points on the tube and creates all of my center lines and intersection points,” said Scott Martin, Romer regional manager Midwest for Hexagon Metrology.

The Romer arm is dust-sealed to allow its use on manufacturing shop floors.

“The one thing that you wouldn’t want to do is have a mist or coolant directly shooting onto the machine itself. Everything is totally sealed dust-wise, but liquids can be dangerous.”

The Absolute Arm comes with a National Institute of Standards and Technology (NIST) traceable bar to simplify calibration. As long as the arm can accurately measure the bar, according to the manufacturing spec, users don’t need to worry about calibration.

“Most metrology devices need to calibrated once a year,” Martin explained. “As long as the arm checks out to the NIST traceable bar, the bar is the only thing you need to send out for calibration.”

Additionally, purchase of the Romer Arm comes with a two-day training class for users to learn the software and measuring techniques.

Martin performed a live demonstration of the Romer Absolute Arm and its software for ENGINEERING.com in the video above.
