Before self-temperature-compensating gages
became readily available, it was common practice to use a compensating gage
to offset the extraneous errors generated by another gage
(the measuring gage
As summer gets under way each year, Nick and Joan Gage
pack their bags and leave Central Massachusetts for their home in Greece.
Manager monitors when calibrations are due, and also offers a scheduling feature, allowing companies to set specific calibration frequencies for each individual gage
GR&R was used to determine if a gage
was statistically capable of meeting the requirements imposed upon it.
The two most effective techniques for improving understanding of generated numbers are gage
repeatability and reliability (gage
R&R), which evaluates the variation in testing equipment and operator performance, and team-oriented problem solving.
cost almost $200, but extra gages
are worth it if they keep $13K machine guns in action and make them safe for Soldiers to fire.
Two anvil gages
, although more difficult to use, are ideal for checking the intended shape of a bore, while the more common three point bore gaging is easier to use, is self centering and is the perfect option for an all-around, accurate shopfloor bore gage
So-called "tempering"--the use of air conditioning to reduce the extremes of temperature fluctuations, while not completely controlling the temperature at the ISO standard 20 C (68 F)--can also lead to misplaced confidence in gages
. Tempering tends to keep shopfloor temperatures within [+ or -]10 F (5.5 C) of some arbitrary value, not the ISO.
The best course of action is to send a few gages
in at a time for calibration, holding some back at the unit until TMDE returns the other gages
Since the range of threads Superbolt manufactures spans to 30", using ring and plug gages
for each thread size and type.
are also indicated for three additional types of applications: where you can expect to optimize tool life and uptime by gaging the part and making corresponding machine adjustments; where scrap rates and loss of productivity are high; and where process variation is expected to be relatively high - measured by a CpK or CP of 1.33 or less.
Many manufacturers never question the practice of using dedicated, functional gages
for production work.
