I often hear, “How accurate can this be measured using CT?” For CT accuracy and precision should be considered together. For accuracy versus precision, picture a target.

It seems that everyone is interested in noncontact gaging these days. Laser scanners, structured light, confocal chromatic sensors, and CCD cameras have all made significant advances in the last decade, leaving us to wonder if this century old technology is still useful today.

Gage management provides manufacturers with data to ascertain the quality of their parts.

I’m a Type-A personality with a sense of urgency to explain everything. Give me a little data, and I will use every statistical tool I can wrap around these rationalizations to help explain an observation. But here is something that I cannot explain: why do we tolerate such poor gages?

For most processes, we have a choice of measurement options that vary with cost. Ideally, we seek the most accurate measurement at the lowest cost with the expectation that the result will be satisfactory. When measurements are critical to operations, we should validate these assumptions.

The official definition of “machine vision” encompasses all industrial and nonindustrial applications in which a combination of hardware and software provide operational guidance to devices in the execution of their functions based on the capture and processing of images. In short, machine vision helps companies manufacture quality goods, repeatably.

NDT has become a critical necessity in order to meet the demanding requirements from users of high-quality round stock bar and tube.

A host of tools are available to metrologists in today’s manufacturing environment. Many are simple, mechanical, and accessible to anyone who wants to measure something.

AMETEK VTI Instruments announced the introduction of its latest LXI instrument, the EX1401 a precision, 16-channel, isolated thermocouple and voltage measurement instrument.

Spending too much (time or money) on part disposition? Start with an analysis of your measurement system. Even a marginal measurement system could contribute up to 30% of the variation seen in your control chart.
