ALSO GIVE REASON

Answer 1

Explanation:

Mectron’s new patent pending Surface Qualifier 7500 (SQ-7500) is a camera-based system that uses statistical learning to inspect cylindrical parts. The parts traverse the machine by being rolled along an angled rail by a conveyor belt so that the camera can get 360 degrees of images to inspect the part.
