Mechanical machinery requires regular maintenance to minimize downtime. Despite strict maintenance, failures can occur, requiring prompt intervention. In some cases, reverse engineering may be necessary to restore smooth functioning, especially if spare parts are unavailable.

The transition from ICE to electric powertrain requires a complete review of the approach to quality and process controls. Some existing checks for ICE find even more extensive applications for the EV sector.

“Measurement uncertainty is the expression of the statistical dispersion of the values attributed to a measured quantity. All measurements are subject to uncertainty and a measurement result is complete only when it is accompanied by a statement of the associated uncertainty, such as the stand deviation."

Many use the phrase surface metrology interchangeably with roughness measurement, but it actually has a much wider meaning that includes measurement and quantification of periodicity; geometry; size; shape and number of discrete features and shapes; height or spacing based statistics; etc.

Olympus’ high-quality optics help eliminate many outliers before they occur. The quality of the resulting measurement is evident in multiscale analysis down to the finest scales.

It seems that everyone is interested in noncontact gaging these days. Laser scanners, structured light, confocal chromatic sensors, and CCD cameras have all made significant advances in the last decade, leaving us to wonder if this century old technology is still useful today.

If you were to ask an assembler at a Tesla factory how they measure the diameter of a piston, the response could very well be “what’s a piston?” If the same question were asked, a traditional combustion engine assembler would likely exclaim “with calipers, of course!”

A depth gage could be as simple as marks on a piece of tape, a line on a ruler, or tape on a drill. Fortunately, of course, modern gages take the guesswork out of measurement, providing a range of simple or high-tech options depending on the job.

For manufacturers in the 21st century, ensuring the products they produce are of the right quality is paramount. 

The right choice of inspection hardware and software for Computer-Aided Inspection (CAI) can reduce inspection times by up to 90% while improving repeatability and reproducibility (R&R) variances by up to 50%.
