Optical measurement in the gear industry.
How does quality control work?
If you're a precision gear manufacturer, you'll certainly know that machining accuracy is a key requirement in this industry.
But...what does this imply?
Let's start with a key figure: the small gears market is expected to reach $684 million by the end of 2025, growing at a CAGR (compound annual growth rate) of 6.4% from 2020 to 2025.
The demand for this type of precision gear is mainly driven by technical developments in the industry to increase energy efficiency and operational reliability. For example, in the application of assembly lines but not only: also sectors such as automotive and watchmaking contribute largely to the increase in demand.
Applications that, by definition, require a great deal of attention both at the production level and at the quality control level.

How does quality control work?
When we talk about gears, whether small or large, we tend to refer to the real profile and the theoretical profile of the gear teeth. The closer the two are, the higher the quality of the gear will be, also in terms of efficiency.
Conventionally, gears are measured with probes in contact with the tooth surface in multiple points or by scanning several traces on the tooth surface through a coordinate measuring machine (CMM).
The resolution increases the more contact points there are on the tooth surface.
However, the overall measurement time for a piece of gear increases as the number of measurement points increases, and this is why the common practice is to measure only a few teeth or a few traces on a tooth surface.
As a result, these measurements present only partial information of a few teeth in the gear.

How can you avoid this issue?
Optical metrology has the advantages of a non-contact method and boasts high resolution and efficiency for part contour measurement and surface quality control.
It allows you to perform a quick, accurate and objective quality test during one or more steps and gives you control over the entire part being measured.
Recently, these advantages have translated into increased demands for rapid dimensional inspection of gear teeth, especially for precision gears.
