Air Gage Readout Accurately Measures Tapered Diameters
IMTS 2018: Western Gage’s Micro IIi air gage readout provides fast and accurate measurements of tapered internal and external diameters.
Western Gage’s Micro IIi air gage readout is said to provide fast and accurate measurements of tapered internal and external diameters. The air gage instrument features a built-in microprocessor, digital and analog displays, RS-232 serial data output, and auto calibration with master gages. Taper angles and datum diameters are displayed with a resolutions as fine as 5 micro-inches or 0.1 micron. Applications include measurement of machine tool spindle tapers, toolholders and medical implant tapers.
The irregularity of a machined surface is the result of the machining process, including the choice of tool; feed and speed of the tool; machine geometry; and environmental conditions. This irregularity consists of high and low spots machined into a surface by the tool bit or a grinding wheel.
Just because dial indicators have been around since the early 1900s, don't expect them to fade away with the last century. This tool's long-term popularity is well earned.
Measuring workpiece dimensions is relatively simple for machine operators but measuring workpiece geometry which involves more complex comparisons of part shape to an ideal shape--is now also practical on the shop floor. The gaging equipment for doing this is coming down in price while becoming easier to use.
