Quality Control

Acoustic emission (AE) sensors detect ultrasonic sound waves emitted when the grinding wheel contacts a part or the dressing wheel and send that information to a process control unit. Monitoring the sound waves and comparing them with reference values allows operators to control the grinding and dressing processes. Variations in acoustic emissions indicate changes in cutting forces, which can then be modified. Some AE sensors are stationary while others rotate with the wheels. Electronic filters reduce or eliminate acoustic emissions from other nearby devices, such as bearings.
3D optical metrology
Focus Variation, the technique behind Alicona's Infinite Focus 3D optical metrology system, has enabled EDM Department, Bartlett, Ill., to measure and see what it is making down to 1.7µm tolerances. Watch this brief report to see the system in action and learn about how EDM Department implemented the system.

Haimer: Easier to find edge with new 3D sensor
The 3D-Sensor New Generation from Haimer USA LLC builds on the success of its predecessor, the Haimer Universal 3D-Sensor, according to a Haimer USA blog post dated Jan. 12. The 3D-Sensor New Generation reportedly features enhanced mechanics, a compact and easy-to-grip casing, and a large 1/100mm dial gauge with two easy-to-read hands.
