Our formula student had an old metal flask welded in place for an oil catch ... no wonder these guys do so well.

Glad to be a mechanical engineer to understand where they DID show the machining part. Infact here's a few of the machining processes that they're shown: 0:34 Surface Grinding of Blank 0:53 Wire EDM to cut the profile (you really do get a machined gear out of that single process) They've also shown a lot of the measurement processes used nowadays, optical inspection etc.

somehow let me remind the life of a bolt video from red bull racing.

This is half life, you didn't show how does the gear dies.

Love this. I believe Red Bull did a similar one for a bolt a while ago

This video should be named the life of mechanical engineer

This is so satisfying to watch .. A raw piece of still being changed por something mechanical :D

The grind never stops

It's amazing how far technology has come.

These videos are incredible

I love technology so much.... Incredible...

The most crucial part: tooth surface preparation by either polishing ( @Roessler) , grinding or the arc wire machining is missing. Also the eventual coating with wcc or dlc ....would be nice. If regtulations allow.

Mechanical engineering it's best engineering

Super quality product!!

just amazing!!!

What is the device the engineer operates by left hand @ 0:18 ? Is it a HW part of that CAD program?

Excellent Video !!!

Awesome vidéo!!! Bravo !

Anyone know what controller the man was using with his left hand in the beginning?

How familiar are you with the gears wars?

which software you use for cad designing purpose

and this is where the series takes off

What's the music used in this video? I like it, thanks!

So they sent the part off to be tumbled and heat treated? I work for a company that can do everything shown in the video without sending off the part.

Wow amazing

Which designing software do they use

Do they use CMM for all the gears they make?

On which software you design?

So each wheel has an electric motor, with a planetary gear box that the actual wheel bolts to? Is this for torque multiplication or something?

That end cars awesome. i want it now.

wow!! awesome!!

Amazing video. Deserves more likes and views

0:19 whats program is that ?

So, how much exactly do you know about the gear wars?

Cool Video guys, very nice👍

i love this

And how much does that gear cost at the end?

It's more precious than a diamond

I enjoyed the video however it seemed like a lot of processes were missing from the video although I'm no gear expert. At 0:54 you see what looks like a milling machine with a fine bit that seems to drill a hole less than a mm deep and makes sparks while doing so. If this is the pre-EDM stage I would have thought the hole would need to go right through the product in order to feed the wire of the EDM machine through it and yet it didn't. Next at 0:58 you see a magic machine that you just put in a blank and out comes a finished gear. I thought it was the EDM machine and yet not only has it done the vertical shaping (by EDM) but also the scalloping (don't know the correct term, rotary profiling??) as though it's been turned in a lathe. Are there machines that can do the rotary profile as well as the vertical profile? Lastly they show a completed planetary gear assembly that seems to be the drive unit that connects the electric motor of the kart looking thing (electric formula student??) to the wheel and hub, etc. As I say, I'm no expert so would appreciate someone explaining the processes and machines. Thanks in advance.

Amazing video :) 1:51 1:55 What are the names of the processes ? Deburring/Vibration polishing ?

This gear actually has a funnier life than me

Could somebody list the processes that are shown in this video in making the gear? For the benefit of noobs

2:17 $11 usb microscope from ebay? :D

Planetary gear in Wheel, nice. But a shame you didn't show the tempering and grinding after.... and the Surfacemassurments not on the Flanks..... well..

hey man can I contact you？I want to make a four-motor racing car

Whats the name of the song ?

No checks for gear profile, lead, runout and pitching?

All that precision work then they throw it in a vibration grinding set and don't test the dimensions after...

Why does the into look like the same formatting to AutoVlog?

this is a perfect gear : )

do they use planetary system?

how about how you made the steel for the gear？

What is the device that designer is using with the left hand??

man, without those we are dead already Thanks

It's by watching videos like this one that I realize that Mechanical Engineering was not a bad choice for me.

00:54 I think we're missing a lot of this process. It looked like a laser cutting device but then it goes under water or some other liquid and gets effectively machined? They are hiding the proprietary technology I'm just curious how that works I thought it was gonna cut the basic blank but apparently it didn't have to Cut through the metal. it cut 2 specific depths like a milling process. Anyone know the name? I'll look it up whatever this equipment is.

I can probably buy a 2017 BRZ with that money.

What is the ”cutting”-procedure called? When the gear is formed out of the raw-material?

It don't seem like a precision gear at all, I mean yeah little bit of surface grinding involved but apart from that EDM machined gear and spline, no gear/bore/O/D grinding involved nothing?

0:14 What is the name of this software ??

which 3d modeling software he is using?

this almost madee cry

good

This is sick...

Looks like I've ended up on my weird recommendations again

that a cool car

No tempering?

what 1:49 process are for

Wanna know what grinds my gears? Perfection.

That's called quality

can someone explain me what is happening at 1:47 ?

Missing a bit the important part of hardening.

can someone please give me the name of those processes ?

What is the title of this song?

never in my life have I seen a machinist wearing a lab coat

what about hardening, maybe one of the most important things..

1:47 what process is this called? thanks

Why did the gears not get hardened!?! :0

Before this was a bolt, now a gear, im going places

can someone explain what the part with all the small pill looking things is 1:50

at 0:18 sec what is the device is used.

A motor at each wheel would make ground clearance a lot more practical on a truck.

really , gear story started with desgin, from hand to with report, many participate to give us one gear

Surface grinding and wire cut EDM Machine

What was that device at 0:18 ?

Ну і скільки ця деталь коштує??

Right, first off I would like to ask yet again! How the hell I got here? Second, I would like to know where to get one of those little F1 cars. They look AMAZING

epic

Was that a plasma torch that operated under water?!

1:12 that part really grinds my gears

You can imagine how much in such meticulously way producted gear will cost.

Have you heard of the gear wars

អស្ចារ្យណាស់

Gearhead would be proud

The attention to the detail given to f1 car parts is insane

there will be a time where subatomic distance of precision are possible

What is the device name 1:28

Only wire EDM?? That's incredible if their process is so good it doesn't require hobbing or broaching!

When the life of a gear is more epic than your life as a human

You know what really grinds my gea... Sorry couldn't resist...
