For precise bore measurements, handheld gages are limited as human feel impacts the readings, especially when checking bores in-machine. A more accurate solution, such as the Indicating Plug Gage, eliminates operator influence, ensuring stable readings and efficient recording of taper, ovality, size, and other crucial parameters.

Air gauges are non-contact devices that utilize air pressure for measurement. They play a crucial role in ensuring precision and quality control in the manufacturing industry, from automotive to aerospace industries. They are particularly valuable for measuring delicate or easily deformable materials.

Following the path of a cheap and cheerful ‘how to do it’ format of the last two columns, I continue with something easy – or is it?

Thread classes for product threads, and by extension the gages used to inspect them, can become a bit of alphabet soup. Some find the requirements confusing.

The measurement of a drilled, reamed or formed hole depth may be inspected in a wide variety of methods. 

The use of the go/no-go fixed limit gage is considered one of the simplest forms of pass/fail attribute inspection.

In my last column I outlined the process for preparing a shipment of plug gages that are being sent to an outside laboratory for calibration.

Many calibration customers become frustrated with their calibration sources because of price changes after they’ve sent a purchase order and the gages to the lab.

Ask what the process is supposed to do.
