Making horns.

[Boyan Silyavski]

The inherent problems of acquiring 5 axis machine is: price and software, so i would forget about that.

It seems to me what you need is precise and sturdy machine, which is well within your budget. Size wise it will be good idea to make all loudspeaker parts with it.

So if you make the part from 2-3 pieces machined cleanly with ball nose bit and glue them together, you will be left with only minor finishing job.

Or once you know that the shape is right you can machine yourself molds and make the parts from epoxy for example, or whatever. There are many many things that come to my mind. MDB or wood and then epoxy impregnate and so on...


PS. Of course i would start doing it the way you have done it till now. Just use 3d paths and ballnose. So when all goes together it will need only minor sanding. If i am not mistaken looking at your photos, it was used 2.5D path not 3d. On your pictures it looks like a 2.5D path or 3d roughing pass, not 3d finishing pass which would leave all super smooth
