I wonder what else that machine can make... imagine the possibilities...

Truly amazing the things that can be done with technology in this day and age. Even as simple as this.

sorry but it's actually made out of Aluminium... only america calls that material by the word that went out of date 100 years ago.

WTF is that? a power rangers helmet?

WTF 120kg block ??? bullshit if its a real sized helmet aluminium is a light ass metal a 120kg block of it would be 44,400sq/cm thats a massive block nothing like the one in the machine also , we can see its the size of a normal helmet as the monitor next the CNC is roughly same size as the block ,
Another thing amazing modern technology , nothing new here there celebratin 50years , i was working on CNC lathes and routers 10 years ago in school there nothing new , and as for the helmet
nice and all
But dont give the CNC all the credit as a human is the one telling it what to do and programming the station trust me there are safety features on such machined to stop damage to its self and the product your making but when it goes belly up and breaks the bit off or even worse your not watching and it gets jammed and burns out a simple stepping motor that costs a few thousand dollars to replace , gota love modern technology for being ridculasly over priced

wtf????
waste of material,120kg of aluminium to make a shiny toy of 3.6kg???
come on people...

For that think this gona work as helmet, they are wrong, this only work as mold or matrix for doing others

#12 You didn't know that metal (even aluminium) can be melted down more than once?

so... the machine etched off 97% of the block? I'd call that inefficiency, but then that's just me...

a programmable machine not mistaken but supervision still exist. How wonderful input to scale that!, maybe more precise this machine than molding.

impressive.
One day we will have machines that can make all kinds of stuff...
for instance MORE machines that make all kinds of stuff!

Good vid to show how those modern helmets are made
#17 Ya, looks like it... but since you can recycle over 98,5% of the Aluminium by melting back the chips... 
Not a lot of waste for a helmet that will save a live someday

Pure aluminum is rarely ever used in machining operations and is typically alloyed with different, heavier, metals. A7N01 (the category type of aluminum in this video) alloys contain at -least- 4.0 to 5.0% of Zinc, 1.0 to 2.0% of Magnesium,and 0.20 to 0.7% of Manganese. Having worked with blocks of aluminum about the same size myself, and having to use an overhead crane to lift them onto the work surface of the machine -- I'd say that's about the right weight for a block that size.

I challenge you to come up with a more efficient way of machining prototypes. Typically after a design has been "perfected" on a CNC prototyping machine, sand based molds of this perfected design are made either by hand or by a special type of 3D printing machine of which makes the mold layer by layer, in mass. Melted metals are then cast into these molds, whose details are then finished by a CNC machine.
However, in some cases, due to the stresses that occur within any type of hot material as it cools (the outside of the metal cools faster than the inside, causing the outside of the metal to shrink, which exhibits pressure onto the hot and expanded metal within the core, and results in structure warping during a machining operation as the stress "releases" ) it may be necessary to "waste" that material each time in order to have a high quality, reliable product.
A perfect example of this is the building of a Ferrari engine. http://www.youtube.com/watch?v=sRKL6hDng-Q

Precision... amazing, makes me wanna watch episodes of "How It's Made" all over again
