Accuracy of EDM and Heat Expansion

[@zaprodk]

That last snowflake-demo - it just gave me that happy feeling inside. It's amazing something can be machined so precise and symmetric.

[@colerobison6916]

I think this is the 20th EDM video I've watched tonight. I'm fascinated!

[@starburst8703]

This is soo cool. Learned about this in the Thermal Expansion and Thermodynamics unit in my physics class. Saw the snow flake in a "The Most Satisfying Video in the Wold" video and I just had to find the source.

[@rob80ace70]

These videos are great. I'm enjoying them. I broke concentration when the snowflake came on screen, it was a big surprise when it popped out. Super cool!

[@lastmiles]

What I find fascinating here is the perfect symmetry of the demonstration snowflake piece. With a rotation of 60 degrees the two parts were still in very close tolerance. Would have been of some benefit to heat the large square piece and to cool the snowflake to demonstrate the larger air gap between the pieces. Conversely one may place a heated bolt or metal part on the center of the snowflake and then it would expand inside the receiving square block to such an extent that it would be locked in place. Only other comment is that the metric system is in general usage in the world and for some reason United States is still in the dark ages here. Regardless most measurment devices are fully functional in metric.

[@Shutout]

wow the part where he heats the block with his hands and measures the expansion is just amazing

[@OlivierLopezCh]

This is so mesmerizing :D Thanks for the lesson

[@MightyMorphinMatt]

Wow. Amazing. Awesome work. Can't believe you guys haven't gotten more feedback on youtube.

[@SteveFrenchWoodNStuff]

Wow! Great video and very impressive work.

[@squidjism]

Insane. This is beautiful.

[@AngryNerdBird]

So satisfying to watch.

[@SSJIndy]

I can't believe these aren't being mass produced and sold as novelties.

[@SpydersByte]

that would be because the manufacturing method isn't exactly cheap, nor is that thick block of tool steel.

[@sasman1964]

@@SpydersByte People will pay

[@googleevil]

THIS IS AMAZING!

[@zbeast]

I have one question... is the snow flake cut out of one section of steel and the hole out of another or did you cut the snow flake out of the same hunk it's sliding into? I don't know anything about edm.. so I don't know how you have to set up or cut.

[@esracoon]

always nice to learn something new. nice vid.

[@Impetuss]

This is incredible

[@dancer4723]

This video is so satisfying

[@KuramaKitsune1]

this is excellent

[@Shnowbound]

beautiful

[@chunkynugget]

Impressive.

[@freethenips]

Incredible

[@Gabbos]

I just want to buy that snowflake, how much for that?

[@Eggsr2bcrushed]

Honest evaluation of the time on an EDM machine that could be spend doing other things is in the hundreds to thousands so I don't think you really want to buy one.

[@MrUltracoin]

Me too. Why is this so hard to find

[@VirUzxZ]

Would totally buy this just to play with on my desk...

[@Kai_Squared]

so satisfying

[@jorgesalves2080]

how can anyone not like the video?

[@housbyrd47]

The second he said they wanted the holes within .0005" of each other I knew that whoever asked for that didn't understand what they were asking for, given the functionality and shape of the part. This video wouldn't be complete without the old school tool maker lecturing the engineer/designer on tolerances. Engineers/designers need to understand what there part is doing, how it's made, and what it costs before they start throwing around +/-.0005" on everything.

[@sixtopian]

Would you say that you go Above & Beyond what others do with EDM? :)

[@CaptainX2012]

Wow.

[@kulturfreund6631]

And the Oscar goes to.... R EDM !!!

[@RobersonPhoto]

THATS NUTS

[@lalabombomful]

the snow flake was beautyfull

[@sjokolademelk]

That is insane. Snowflake part almost looks animated.

[@iSk00L]

I want that snow flake thing

[@arif1984may]

applausable!

[@wendel5868]

Dat snow flake tho.
