Checking for surface defects is an important component of measuring product quality characteristics. Increased productivity leads to accelerated production processes and so production technology is used to the edge of its effectiveness, significantly increasing the risk of a nonconforming product.
Quickly and sharply look at each piece of surface
Surface defects are a very specific phenomenon. Despite the apparent harmlessness, they can have a significant negative impact on a product’s functional characteristics, or leave the impression
that an end customer’s operations are malfunctioning. Rotating parts are particularly very sensitive to surface defects.
Detecting surface defects is one of the most demanding inspections encountered, so special optical and lighting systems are utilized to detect them. High speed and inspection resolution are the main requirements. Often, the goal is to detect very small surface defects measuring tens of microns. Some surface defects can only be detected by a change in the relief. Here, direct or hybrid 3D technology is used (laser scanning, collimated illumination, and Shape-from-Shading).
Advantages and Benefits
- Provides a very high resolution of the sensed image;
- High system flexibility;
- Combines different sensing methods;
- Moves along the product at a high speed during sensing;
- Inspects all production;
- Customers develop the optical and lighting systems;
- Optimizes solutions for specific applications.
