The need for long-range height measurements has been around since the principles of lay out work became a fundamental requirement in machine shops. 

The precision length calibration process is very much like any length measurement process, but taken to a significantly higher level. Both processes are composed of the same elements.

Screw threads are one of those important elements of mechanical design that are often taken for granted but find usage in critically important applications.

As with every other function in modern manufacturing operations, inspection is subject to the management team’s efforts at cost control or cost containment. It is good business sense to maximize the value of every dollar spent, but it also means that hard choices must be made when selecting handheld gages.

Surfaces are designed into products to reduce friction, “store” lubricants, provide a high luster finish or be the proper texture to hold paint (but not show the actual surface of the paint). 

Air gaging has many advantages as an inspection method. It is quick and easy to use, and requires little skill on the part of the operator.

It’s certainly not news that more and more gages are being forced out onto the shop floor. Tight tolerance measurements that were once performed by a trained inspection technician are now being done right next to the machining center, most likely by the machine tool operator.

As part tolerances tighten, both form and surface finish have a bigger influence on the size and function of the product. And with pressures on manufacturing to be more productive, it is no longer viable for checks of surface or form to be performed on a measuring system in a quality room.

Calibration is not just about having stickers on your equipment with dates that say everything is okay.
