I'm looking to have a part cut from .25" (or .1875") x 2" x appx 9" 6061 aluminum bar stock. I've cut them on my converted rf45 clone, but the motor went out and I need to have the rest of a production cut.
It would be for 10 pieces total, 5 each of nearly mirror image parts. I'm currently cutting them at .005" passes and it takes around 2 hours per piece. I have an idea that will speed it up considerably, but requires some tooling I don't have and an ability to accurately match an endmill bottom with a 3/8" corner rounding end mill bottom, which I can't really do at the moment either.
The processes I have in mind would be:
1. Cut out the profile of the piece with an endmill, all the way through the part.
2. Accurately place the corner rounding endmill, and follow a similar, but larger profile in order to make a pseudo elliptical fillet on the edge of the part.
3. Accurately place a .125 corner rounding endmill and follow another profile, but this portion would be a standard, circular fillet.
4. Drill 2 through holes
4a.Countersink these 2 holes for a #6, 82 Degree, Flathead screw.
4b.Tap these holes for #6-32
Please send me an email at [email protected] if you have the capability and we'll discuss it further.
Thanks.
