Rooting for Analysis

Would somebody please ask Mike Micklewright to stop making sense (“Why Root Cause Analysis Sucks in the United States,” http://qualitydigest.com/IQedit/

Giving Thanks

I have been a faithful and interested reader of Quality Digest and the “Quality Curmudgeon” column for many years. As is usually the case, I breeze through the magazine and then cut out the last page so I can take my time with it at a later point in time. I started this back in the day when I realized I cut them out for future reference or to forward to a colleague anyway.

The hydraulic casting components made at Rexroth Guss, a subsidiary of Bosch Rexroth, are characterized by their complex, core-intensive construction and many free-form surfaces. These costly parts, made of cast iron or spheroidal graphite iron, are invariably designed in 3-D CAD software. The transition from 2-D to 3-D design prompted the quality department to look for an appropriate measuring solution to inspect their parts.
