Have a look at this clever video showing machining by strobe

Interesting video but one turning process which made me stand back in amazement was some years back before I finished working, I visited a customer who machined brake discs they were done on a CNC machine using ceramic tooling at speeds I just could not belive and at time maching 3 area's of the disc at the same time. The discs were the vented type and when loaded into the machine a raw casting and within a couple of minutes produced a piece that could have been bolted straight onto a car.

Gosh - raw casting to completed brake disc in a couple of minutes, where's the fun in that?

Or the agonising heartaches wondering "how do I do this bit" moments followed by a cup of tea and a long ponder, for that matter!

When we are at it...

This will take a lot of tea if it was to be made in my workshop

The link that Mogens has shown is the joining together of two existing types of machine, the machining centre and Anthropomorphic robots, both have been in existence for twenty or more years, watch a Robot build and weld a car together these are generally five or six axis machines and they have now been put in a cabinet to produce the machining centre.

That last machine looks like a solution in search of a problem. The essence of engineering is to produce a value added product, i.e. punch it out in seconds , spray it and sell it. I wonder how the G code for this object was made, I suspect it was taken from a hand crafted model by a copying device. So why not just electroplate the original and then use that as a basis for a lost wax casting process. Rescaling the workpiece would be easy, likewise stretching it in any axis would be easy, but to replace the moulded on logo, I suspect would be difficult because the new logo would have to have the same contours underneath, as the unseen surface of the original helmet.

Certainly as a piece of engineering its VERY impressive!

Frank,

Putting Logo's on curved surfaces is easy these days, basically 3 clicks of a button.

 

EDIT OK found the link I wanted.http://www.textualcreations.ca/TurboCAD%20Tips/TurboCAD%20Tip%202.pdf

 

The use of the helmet whilst being impressive isn't really a good example of what these can do but if they use another model chances are many wouldn't see it for what it is. As the helmet is an easily identifiable object it stands out more.

 

These video's are not about the finished article, more about processes.

 

The one with the F1 V8 block again is impressive and I believe that some companies use this method on one off and very limited runs. However Mr Ford wouldn't be interested in doing it this way, too time consuming but he'd like the facility to do his one off mould for casting this way.

 

I'll also bet the the helmet was modelled in CAD first for the prototype moulds to be made. Far faster than hand crafting a mock up in clay as they used to do and even easier to change something. There is a whole new industry out there now working with 3D models that never existed 10 years ago. It's the way engineering is evolving.
