need help with toolpaths

[itsme]

I am a student at a technical highschool, i have been working on cnc machines only for a little while. Im having a problem creating a toolpath for my part, i was wondering if anyone could help me... the program is in the ftp under the mc9 file, the name of the file is "steering-wheel"

 

-Thank You-

Funny Mike, but true.

Didn't someone else try cutting a steering wheel not long ago?

itsme,

could u be a little specific about that questions such as ur requirements etc., maybe we could point out the machining strategy that would best work...............

I downloaded the file (it was in the root dir not mc9 folder )

Are you planning to make this out of 1 piece of matl? If so then a surface rough pocket would be in order, first, I'd face off your top view then put the holes in. Then flip it over, machine down (bore a hole) to the flat face, flip it back over then surface rough pocket down to the center of the 1" dia outside profile, then try a few finish machining ops flip it over again and surface rough pocket to remove the inside matl surface finish ops again and you should be there.

The best approach would be to make this out of two pieces, make the center ring flat and have it bent, cut the tubing to length and have it formed, weld the two, done.

 

Nice model.

I think I would turn the silhouette in a couple of ops, then mill the rest...
