CMM fixture slashes internal rejects by 98%

Article Abstract:

A Rayco coordinate-measuring machine (CMM) enabled Opticord Inc. of Palatine, IL, to reap benefits ranging from a 98% reduction in internal rejects to the elimination of the 20% order-reject rate and the 30% late-delivery rate. Prior to the installation of the CMM fixture, Opticord was losing customers owing to poor quality products, late deliveries and rejects. The CMM system, which allows programs to run with minimal operator input, is also highly accepted among operators. An eight-week course on quality-control techniques and a four-week course on statistical process control and advanced CMM use were conducted among operators.

5-D laser cuts setup time by 80%

Article Abstract:

Gaithersburg, MD-based Automated Precision Inc's 5-D laser provided a solution to Boeing Commercial Airplane Group's time-consuming machine tool calibration time. A research project on machine-tool mapping and real-time correction revealed that the 5-D laser can reduce setup time by 80%, and is better equipped to satisfy the Federal Aviation Administration requirements. 5-D laser is also capable of including production machine tools in a calibration schedule and can possibly eliminate end-of-line inspections.

Wanted: appearance-measurement tools and standards

Article Abstract:

Spatially-based instruments that accurately measure product appearance can be developed by standardizing current flux-based tools and creating models for each appearance factor. Except for color, devices that measure other factors that influence appearance such as gloss, haze, distinctness of peel, roughness and texture remain wanting. Appearance-measurement tools are important because customers equate quality with product appearance.
