Today, most surfboards are made with a CNC machine. 3D metrology laser trackers can assist with critical quality control safeguards to ensure the CNC machine is doing its job properly.

3D measurement tools offer incredibly precise and accurate measurements. However, using them correctly requires specialized knowledge, and integrating them into current processes can be quite complex.

This article discusses the connection between surface finish and factors like friction, wear, and fatigue life. It explores how precise surface finish measurements improve product reliability and analyzes the evolving measurement technologies.

Manufacturers are facing stricter regulations and quality standards. Portable CMM arms help maintain exceptional quality control as they navigate these requirements.

The manufacturing industry relies on precision for safety and performance. Shaft measurement instruments are crucial for ensuring the functionality of mechanical systems.

Michelle Banger, Managing Editor of Quality, talks with Matt Noonan. He's the Quality Manager of Pratt & Whitney Measurement Systems, Inc.

Automation requires precise data and careful attention to uncertainty, especially in longer processes with less human involvement, according to Chris Gordon from Optronic Laboratories.

I kept waking up at 7:47 and also noticed the same time on the clock in the evenings. When I mentioned it to my niece, she said it happens to her too, at a different time of the day.

Traditional manufacturing often results in waste of materials and energy due to imprecise measurements. 3D measurement technology enables precise measurement, early issue detection, and process adjustments, reducing waste and costs.

The push for smaller, more complex device components has spiked the need for precise, non-damaging metrology, with 3D X-ray microscopy (XRM) leading the way. This technology offers high-resolution measurements critical for quality control in the electronics and manufacturing industries.

Digital connectivity is a driving feature of our lives. While invaluable in our personal lives, it also has the potential to transform manufacturing processes. In many cases, this has already taken root. But in one area – 3D measurement activities – it has so far not been used to the fullest.

Is it time for our industry to consider using pascals for static pressure measurements? What would the transition from inches of water column to pascals look like and how hard would it be?

Capacitive voltage transformers (CVTs) are used on higher voltage levels, starting from 66 kV and upwards. The type of the CVT is always a single-pole one, thus the connection is between phase and earth. The higher the voltage level is,... Read more
