Whether you’re a small machine shop or a large multimillion-dollar manufacturing giant, there’s no doubt you use dimensional gauges to maintain the standards for quality in your production.
The accuracy of these dimensional measuring instruments…

When we think about making a simple measurement, such as an outside diameter, many methods can be used. These would include calipers, micrometers, mechanical snap gauges, air snaps, CMMs, and special fixture gauges, just to mention a few.
The…

Electronic temperature compensation in gaging has become a valuable tool in improving the accuracy and gage repeatability and reproducibility (GR&R) of gages in harsh manufacturing environments.
The need for temperature compensation comes into…

We ended the previous gaging article talking about the 10:1 rule as it applies to the performance of a gage.
The rule says that the gage should perform to a level better than 10% of the tolerance. Although this rule has mostly been replaced by the…

In this job, I get a lot of questions. In fact, I did some figuring the other day and estimated, conservatively, that we have probably answered at least 50,000 gauging questions over the past 35 years or so.
Some of these questions have been…

Inspection is often subject to the management team’s efforts at cost control or cost containment, as is the case with most other areas in modern manufacturing operations. Although it’s sound business judgement to maximize the value of every dollar,…

Before a fixture gauge is designed, the engineer must understand what specifications must be inspected. In many respects, the gauge’s design reflects not only the design of the part but also the manufacturing processes that produced it.
Machinists…
