ZeroTouch® Application Notes: Gear Inspection
2Pages

NON-CONTACT 3D GEAR IN-LINE INSPECTION SYSTEM Our client sought a new solution that would accurately measure all of the helical gears produced in real time. • ZeroTouch measured the entire part surface, generating a high-density, micron-level point cloud. • ZeroTouch executed the inspection plan in just 30 seconds versus the tactile methods, which took 10 minutes. • ZeroTouch measured all surfaces on every gear tooth in 3D and identified surface defects too.
