Thought some of you might want to see modern engineering at its best!

absolutely top drawer, i wonder how long it took in total???

how do you go about programming something like that?!

If i won the lotto that would be the first thing I bought.....along with a person to design and operate.....

3D CAD model which then gets converted to tool paths by some rather clever software (probably under guidance from someone who charges by the hour).

There's a video on youtube of a v8 being cut from billet.

yeah, but look at the detail in it! i get frustrated just doing flat simple shapes! lol

2min13secs in nearly made the vomit - the imperfections inside the helmet were a flippin disgrace...

with modern cad packages 5 axis machining is very easy compared to back in the day when you had to write the programme.....

Nothing I can't do with a cheap Dremmel copy......

Some of the guys I work with worked on a 3D scanner (basically a metal probe on a 3 axis sensor) about 18 20 years ago. You just plonked you object in the scanner, the scanner did its thing and the program for the 5 Axis mill was created. They used it to scan stuff like those beetle boot jack things and produce the dies to cast them from a model. They recon it would have taken about 2 days to scan that helmet though! (On a 12mHz 286 - state of the art at the time)

How is tool wear accounted for in something as sophisticated as this?

very indeed, could watch that kind of thing all day.

Yea! and lack of liquid coolant some sort of refrigerated air blower?

Tool wear is irrelevant on that sort of thing to be honest. You would only be looking at a few microns.

Coolant wise, as long as the alloy is nice and machinable (which it appears to be) and the cutters are running at the right feed and speed you dont have to have any coolant when machining aluminium. Though it would help to prolong tool life.

You can get liquid nitrogen coolant systems now, but those are mainly for hard turning operations using CBN cutting tools.

Sounds like I need that due to my CBA cutting technique

i remeber the days when you had to sharpen everything...

good ole hss eh?
