Gage Block Introduction - How To Use and Calibrate Gage Blocks

Рет қаралды 88,407

Күн бұрын

In this episode of the Metrology Training Lab series by Mitutoyo, we learn how to calibrate gage blocks, stacking or wringing gage blocks and a brief history. These simple little blocks are something special. Each one with their flat and parallel surfaces and with an accuracy of just a few millionths of an inch. We’ve used gage blocks in previous metrology lab calibration episodes, but in this episode, we get to understand them better and appreciate their role as a premier measurement standard.
Gage block faces are very flat and very smooth. The reason for this is that allows the gage blocks to wring together. Without using any adhesive, gage blocks can be brought together and the flat smooth surfaces will adhere to each other without causing any damage. And they can be broken apart and reused over and over. And when done properly, the gap between wrung gage blocks is somewhere around one millionth of an inch. And any flat smooth surfaces will wring together. Steel to steel, ceramic to ceramic, steel to ceramic, and even gage block to optical flats.

Thank you for the video and the series. I have had an on going debate on the use of light oil to wring gage block; this video let me settle it finally!

@@MitutoyoAmerica using WD-40 was informative and actually reassuring: you don't need anything fancy to do the job, just a thin film of light oil. I had been wringing dry. Beyond the knee-jerk opposition you knew to expect, it might not be the best for those who don't keep steel blocks in a low-humidity environment. WD-40 is basically kerosene with a penetrating oil that's volatile enough to evaporate, plus fragrance. This might leave the blocks vulnerable to corrosion if not used often and the oil evaporates away. I would love to see you use more WD-40 where appropriate, if just to irritate those with an irrational aversion to the stuff. Thanks for the educational metrology content, good thorough authorative information can be hard to find on this topic.

How about showing interferometric calibration at japan which is used for Grade K? I've seen the Mitutoyo Gage Block Interferometer for sale in the Japan catalog, it is not listed in the US catalog-every government has export restrictions for its good stuff.

@ericandersen2590 5 жыл бұрын

They are used on the ends of the stack so that you are taking the measurement off of the wear block as to not scratch the other blocks...then over time you will only have to replace the wear block.

It it acceptable to use the oils from your fingers to get them to wring together?

@MitutoyoAmerica 5 жыл бұрын

That's an old school method, particularly the oil from around the forehead or nose. While I can't recommend it, I have heard that some people use it successfully. However, there is concern about the acid level causing rust. If you do it, be sure to clean it off promptly when done.

How often do the blocks need to be verified or calibrated?

@robertbach9376 Жыл бұрын

This is often a question of storage conditions and frequency of use. I'm comfortable doing it every 2 years, as our products never need measured to the tenths. Often when you send them out for calibration, they will give you a recommended interval for calibration.

Flat surfaces....."Clinging"......."Wringing" versus possible "connection": I found the "Wringing" aspect very interesting. Appreciate you explaining of everything in detail. I found it interesting you said a tiny bit of oillneyness(clean) may add to the wringing effect. Far from this I used rough "clinging" effect. I made 2x jaws lying loose in michinest vice, had them milled squared. On them I fit fasteners(variable) to hold objects I want to do stuff with. As I open the vice, due to layer of grease , I do not have the problem of the inside jaws coming loose from vice, it sticks, the grease solved the problem, "clinging". I just thought about the theory of wringing........ Currectly the best gage blocks are flate to a certain standard which will have ringing work good. Now this is at an accuracy that is not 100% flat to infinity-0000000... Out of this my theoretical question would be, say for instance in the future these surfaces could be get 100% flat(chemically/electrically, what ever method) to infinity 000000, what do you have in your hand holding two of these flat surfaces apart, and then join them at 20c: 1-100% dry. 2-80% dry 3-50% dry x-...or humid(clean, contaminated normal air, vacuuum etc). Y-..I refer here to immediate contact, not left over time. With all the above in mind, could you have a "connection" with a different meaning than "Wringing".................just wondering, and have a problem getting them off each other as a result.

@hughmac13 5 жыл бұрын

I don't think that the "flat to infinity" that you theorize is possible. Molecules are not flat; atoms are not flat.

@ModernBladesmith 4 жыл бұрын

@@hughmac13 that's not flatness. You're thinking about consistency. Ofcourse theoretical flatness is possible, but not ever likely possible with technology, however we know that anything is possible, so something could become perfectly flat, but the likelihood is almost impossible due to temperature fluctuations in different parts due to air currents and what not, but the problem here is something would only be flat for a mere flash of time, then uneven expansion on an extremely small scale (bordering atomic) would be bound to happen and its flatness would change to an imperfect flatness.

@urwholefamilydied 2 жыл бұрын

10:45 oh, duh... of course wringing works and isn't magical... ever try picking something very flat off your kitchen counter when it's a little wet? Didn't know you guys normally used a thin amount of oil. That makes perfect sense now.

How often should gauge blocks be calibrated?

@MitutoyoAmerica Жыл бұрын

Thank you for your question. For calibration cycle of any gages, everything is depending on following items: • Is the gage main master or secondary master for calibration • What is the use and storage condition of the gage, (temp & humidity, dust etc.) • What is the tolerance of the gage and the process that you are going to use it. If you need guidance for this you can visit Recommended Practice - NCSL International ( ncsli.org/page/RP ) and buy RP-1: Establishment and Adjustment of Calibration Intervals.

Wringing gage blocks can be a challenge. Make sure they are thoroughly cleaned. before you get started. When wringing the blocks, feel free to use some level of force as you slide one block onto another. Press them together while sliding.

@timthompson468 5 жыл бұрын

goofyfoot2001 Good point. I get the idea of how to handle and wring them, but I’m not sure how they’re used. I assume you use them to check your measurement tools in the range of a specific measurement you’re making. So if I’m using a micrometer to measure a one inch piece, I’d check it against a 1” block, but does one adjust the calibration to match the gauge block or just adjust the number to account for the error?

@hughmac13 5 жыл бұрын

In practice they're used for the calibration of gages, to check that your micrometer is accurate. In a more theoretical--though still practical--sense they ensure (as long as they're accurate) that my inch is the same as your inch is the same as the inch at Boeing is the same as the inch at GM is the same as the inch at NIST. And so on. Everyone's inch needs to be the same (± a very few millionths) so that the jet turbine parts that a variety of companies make can all fit together tolerably at the Rolls-Royce plant and then operate without blowing up and killing millions of people.
