Ever wonder why Bugatti Veyron engines cost so much???

I feel so sorry for the poor bloke who had to write that CnC program :eek:
 
CnC is the code to tell the machine how to shape the aluminium - a stage after designing the block on CAD.

But you won't be sorry when you think of the salary he'll be on!
 
and they still couldn't design a decent body for it, got to be one of the ugliest cars there is :whistling::exit:
 
Surprised they can machine some of it dry. Ali is sticky stuff to cut.

CAD is the drawing bit... CAM is the getting the machining code from the drawing. Software can do a lot of it but there is still plenty of human skill involved in getting the program right.

I only used to work in 2 dimensions for coding though... sheet metal.
 
I used to program CNC machining centres, and as Robertp says software can do a lot of the work. Also on newer CNC machines it's not a G codes anymore.

As for dry machining, it's all in the speed and feeds (and cutter I guess)
 
not bad piece of machining there, i used to do stuff like that :) full 3D CNC programming and machining, F1 and MOD stuff mainly, tooling and machines have come on a bit since i used to do it though. I even made it into the magazine of the company that made the machine i used to work on :)

I thought that until i clapped eyes on one......when it's in front of you, it looks sublime :love:


As for the dry machining, that surprised me a lot!
Especially when you could see the amount of material being removed in each pass :eek:
 
it wasnt actually taking that big a cut DF only a few mm deep, i wouldnt be surprised if it wasnt being fed with a mist of coolant or air jets direct to the cutter tip, it wouldnt show on the video.

I dunno m8, the shards of material looked pretty big and they were big enough to make a noise against the safety screens around the work piece.

Re the cooling, the block didn't look like it was wet or dripping during the "dry" phases.....with your engineering background, do you think it'd be possible to air cool a bit of that size spinning at that speed?

I've watched sheet aluminium being friction welded during manufacture of the double deck air bus wings in a not too dissimilar process.
 
the cutter looked like a tungsten carbide tipped tool, high speed thing, running very fast, anything coming away from that would make a din against the plastic screens around the machine :) no more than 5mm deep per cut going by the video. If you cut too deep, or get too hot you stand a chance of stressing the aluminium, not something you need really, specialy with the stresses and strains that will see.

Cool air or mist could be pushed right to the tips of the cutter, they were able to do that 12 or 13 years ago when i was doing that, so ot quite sure what they are capable of now.
 
And now you know why VW lose over 3 million euros on each one they produce!
 
What a cool bit of video. Thanks for sharing that with us Woodsy. I've got to pass that on to a mate now. He'll love it.

Mick.
 
:D Glad you liked it chap :)

NathanJT, are you talking about the engine or the car as a whole? If the car as a whole, it's more than that... each car is £5M to make but they sold each one for £800K, making a loss of £4.2M on each. Bare in mind, it's a concept car... it was never intended for mass production.

Oh I saw you lived in Chester and was hoping it was somewhere local!

Sorry nope :( is one in Manchester tho if that helps, it’s a cream and black one with black/silver old style number plates

I knew it was a lot. I recalled TG stating that each one cost around 4.3 million to make. Couldn't remember if it was € or £ though.

Awesome piece of engineering though. Not quite up to Concorde's standards, but damn close!

I got pics of 2 of them, including the one that got done for speeding on the way home and still think the are ugly

Chances are I've got a pic of the car it was racing too.

The photo of the engine doesn't do it justice.
I'd prefer a Aston Martin :D

That kind of reminds me of those printers that create solid objects from CAD drawings using some weird material that solidifies. Ever seen one of those?
