Wire EDM, not sure if this is possible

[cncworker]

I got this part handed to me today. I've wired this part before, but now they added the 2x 3/64 chamfers. Not sure how to go about this. Is it even possible to wire? Using Mastercam 6x, i know, i'm behind. Wire EDM is Mits FX20. Any help is appreciated.

In one setup I say no. You would do everything you can from the 82 side and maybe can get those 2 other faces, but if you are talking about along the edge that look they are 90 deg to that corner, then I see that as another setup where the wire can cut through the part and not hit anything. I always had to imagine the wire being able to pass through anything I was given to cut. Then I would develop my setups and then programming form there. I have had some 4 to 6 setup stuff I have had to do, but as long as I could pass a wire through it I could do it.

 

Edit without seeing a 3D model I am going to say no cannot get to these 2 areas with a wire.

If these are the 2 area then I think yes with a different setup.

Thanks for your reply Crazy^Millman. The second reply with the one with the bigger angles i am talking about. The first ones you mentioned are flaws in the drawing. Ya, i'm thinking a separate setup too. Not sure what i'm going to do yet. Thanks for your input.

Does your machine have enough travel to cut them in the same setup as the 82 deg angle? You are not planning on doing the 82 deg and the profile in the same setup are you? Is the material already at 82 deg when you get it? What kind of machine do you have and what is your travel capacity?

Seems like you would have to sinker edm the 2 angles to me after wedm.

The 82 deg angles will be milled on or ground on, not sure what i'm going to do yet. Then i will do the wire work. The angles in post #3 are my concern.

The machine is Mitsubishi FX20. Not sure on travel, but there is plenty. I guess i should ask the boss how he thought we were going to do it. He's the one that quote it. Thanks for all input. It means a lot to me. Sometimes i get stuck on projects, so i come to this forum. Very valuable too!!

grind on after wire

[crazy^millman]

I always worry about coming to shoulder with grinders and keeping the edge. If I could get to it from the same position as the other work then I would try it there. If not then mount at the angle needed to machine with using the wire and be done with it. Old trick I would do it program my machine to move 45 degree angle and then use that to help me to indicate my plates in if I needed to mount them at 45 degree angle.
