Hello Paul
I was using foamworks which is good and it does not have the 5th axis.
It would be nice to have this facillity, to cut eliptical wings for aircraft.
I was using the stepper driver UCn5804b, one channel stopped working.
I was told that this chip is no longer available. I rebuilt the controller using
the GMFC french site. This controller works well and is cheap to build but the software
is more expensive than foam works.
All the software that I have seen on the net, have not the 5th axis.
Another way of machining foam is with sandpaper glued to a mandrill cutter.
Using a 5axis router with B and C axis you can then cut 3D.
This method is a bit messy as foam dust goes all over the place.
In the automotive industry they use this method for lost foam castings. |
