5 axis toolpath

[jorges]

Hello all,

I'm just getting into 5 axis machining and have some difficulties trying to cut the undercut shown in the model. The idea is using our 5 axis machine to cut the step with a ball end mill instead of slitting saw type of cutter from top. I threw a few tool paths without luck but have 2 of them that look close but not quite right.

We have a Haas 5 axis Trunnion that would like to use more often.

Attached is X7 file.

Any help would be appreciated.

Thanks

That path on a turrion is going ot be difficult like you are planning it. Pinching will be my concern. I think you are too worried about keeping the tool normal to the surface. I would look at kicking my tool so you get away from zero surface speed at the tip and stay at the side of the ball tool so you get good chip load and surface speed. Sue some Vectors to control you path and good to go.

It seems like that part would be better turned than milled.

Beat me to it. Turn it up then make 2 per blank. I get it if no access to turning center though. Mill turn would be optimal.

How about turning the part and performing the secondary operation with Wire EDM?

Just coming back from vacation. Thanks for your input.

There are more features around the part not shown on cad file that need to be milled, that is the reason of machining it on a 5 axis machine would be a better option (also material cost).

I need some help choosing the right parameters of the toolpath to be able to make it work. I think Flow 5 Axis would be more apppropiate for this specific cut. What do you guys think...?

I played with parameters without luck, for sure I'm missing something basic to make it work.
