I have a couple of robofil 290P machines and usually cut straight work with an occasional job that needs 1-3 degree or so for die slug clearance. My machines do not have taper expert on them. I took in a job that needed a u shape path cut in it with 17 degrees on the left and right and 20 degrees at the back 1/8 radii in the corners in 5/8 thick 4140ht. Kind of like a 3 sided funnel. I wasn't sure if I could get the 290 to cut those biger angles or if I would end up in a machining center doing it all with a ball end mill . The 290 did it with some tinkering around with the gen settings and the parts turned out close enough for the wide open tolerance +-.003.
The big question in my mind now is just how steep can I go with .010 soft brass before it becomes too much for the guides/wire/flushing etc. The 290 has the same uv travel as the xy so it isn't physically limited on where the guides can be. What I am looking for is how steep of a taper and in what thickness have you guys been able to cut before it became a flushing nightmare or other issues made it unacceptable?
