SPC for the small shop starts small, taking one step at a time and keeping operators involved. Using wireless gaging, operators don’t do more work: with this simple automation, they still measure the parts, but now they can watch their measurement data being collected right into the spreadsheet.
This primer on various measurement processes by George Schuetz of Mahr Federal shows you how to match different caliper designs with selected applications to prevent measurement errors from creeping in.
George Schuetz of Mahr Federal explains why air gaging has become the inspection tool of choice for controlling the critical parameters on these devices.
The nature of a part’s surface should be determined by the part’s function: a surface that fulfills the engineering requirements of the application, without wasting time and effort on a higher quality finish than is necessary. Maintaining good control over surface finish is not just a challenge, but an opportunity.
