Quality Control Processes

Bonal Technologies Inc. offers its new Meta-Lax 2000 Semi-Automatic Touch-Screen System.

Shop Operations column for June 2010 Cutting Tool Engineering magazine.

Using the design of experiments process for QC on the shop floor.

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.

Continuing to provide the Quadra-Chek metrology digital readout for 2-D geometries, Heidenhain Corp. introduces it with a new dark gray faceplate. It is now called the Quadra-Chek ND 1200.

The benefits of performing tool breakage detection with a noncontact, laser-mounted monitoring system.

A rational approach to machine tool selection.

Improvements in inspection equipment and techniques have evolved dramatically over the years.

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.n

Ways to control temperature effects to improve part quality.

Using on-machine inspection to check part quality can reduce lead times.

One machine shop's strategy for achieving zero-defect production relies on making all shop floor staff responsible for quality.
