5 axis CNC Mill Used to produce Aluminum Motocross Helmet

[Burning1]

The Japanese Company 'Daishin' used a CNC mill to produce a full scale replica of a motocross helmet. The piece was created in celebration of the companies 50th anniversary. The result is quite literally, a work of art.

To someone who doesn't often see a CNC mill at work, this is pretty awesome.

Real nice work...

 

[scotinexcile]

Exelent,still really cool though

 

[Burning1]

God damnit.

 

[Mike95060]

Its pretty nice for someone who DOES see a bunch of CNC work regularly too!

 

[auntiebling]

God damnit.

god doesnt' care about the repost gestapo, neither should you.

 

[mean dad]

i didn't see the original, so i don't care if it's a repost or not.

very fucking cool.

 

[nazgulnarsil]

i should look into the math behind CNC programming. seems like a pretty neat and useful application.

 

[tuxumino]

wheres the money shot?

 

[Karbon]

i want it to machine an aluminum pancake.

 

[Wannaduck]

Didn't see the original either. And even if I did, I think it is really cool

By the way, did it pass Snell?

the math is just trigonometry and interpolation, not terribly complicated. the computer programming... i have no idea

 

[nazgulnarsil]

yeah, circular and linear interpolation. but actually coding it up so that you can take something from solidworks or CAD and mill it in 3d gets complicated real fast. luckily google books has a full textbook on CNC programming available.

This article is actually a re-post from slashdot. There's a lot of interesting information there.

To summarize a few of the comments... The software has two components... The first is a 3D CAD/CAM modeling software that produces the desired product model. The second part is the software that takes the model, and actually produces a cutting path for the CNC machine. From what I was reading, there's a huge amount of complexity in producing an optimized cutting path for one of these machines. Beyond efficiency, the software needs to take into account the inertia of the robot, and the amount of force that can be applied to the cutting tools.

Using the software (cad/cam) and the creating of the program is only one thing (and alot of the times, the easiest part), the tooling and fixturing is way more complicated. Thats where the real machining skill comes in. Knowing how to mill the material and with what tool. Impressive none the less.
