BIG job, done on a small machine..
« on: September 08, 2009, 20:26:25 pm »


a 48Cm long scale 1:144 Boeing 747 made out of Solid aluminium, my machine can only travel 28 Cm, so i had to machine the fuselage in 2 parts..

3D shape drawn in Inventor, Code made by CamBam.. total machining time?.. close to 100 hours..

Arie,

I would consider it a major achevement just to machine that on one piece.
To have to reposition it on the machine and continue cutting and keep the alignment is beyond my comprehension. :o

I look forward to your tutorial  ;)

Cheers
Peter

well repositioning and aligning was the easy part..  ;D

since i machined it out of solid billet, i just aligned the side of  the billet along the table edge..

a notch milled somewhere halfway was used to shift my reference points..
it's not that hard after all..

creating the loft features in Inventor took me a day, for just the fuselage.. wings took 3½ hours to design, tailplanes half an hour each, and then the motors.. all desgining took about 2 days...

Do you mind sharing the methods you used? Such as which 3D method in CamBam

Also step over for roughing and finishing, and end mill size.

I'm new to cutting 3D and I am trying to find a good place to start as far as parameters within CamBam.


Thanks, Scott

well.. maybe if you throw it hard enough...  ;D, i think it will give some realistic readouts if you'd put it in a wind tunnel..  ;)

for machining i still used the old 3D bas-relief mop, i didn't yet have the new version of CamBam on my machine.

feeds were around 1200mm/min, stepovers 0.5-1 mm, depth increments 1-1.5 mm

mind you, you will need a strong and stable machine, and a powerfull spindle as well.. most of the machining was done with a 6 mm ballnose

That's pretty impressive! Since I'm wrestling with how to machine longer piece than the table I appreciate even more with what you have accomplished. Congratulations.
 BTW, how did you tell the CamBam where to start & stop? Thanks.
