Machining fillets

[Richie_B]

Hi

I would appreciate any help on machining the top fillet on the enclosed file.

I would like to use a Ø8.0 mm bull nose end mill with a 0.5mm corner rad and maybe something like a 3d contour toolpath

thanks in advance

Here's a couple of ways.

3D contour, advantage is smaller program and better smoothing. Disadvantage is not a constant stepover on the surface.

Scallop, Advantage is a more constant stepover but if you look at the corners you'll see it's quite wavy in the Z axis so you don't get good smoothing and arc fitting.

Files attached.

Edit. Forgot to mention I added a patch surface I've selected in the 3d contour op to stop machining the inside of the pocket. It's selected on the geometry tab under model so on this op sees the patch, it's not selected in the setup.

@seth.madore  Can you take a look at this design. When I  first tried to generate a toolpath I got this.

After investigating I found an extra body that was hidden got selected while creating the setup. Seems to be because the folder is hidden but the body still has it's light bulb on. I think a body that's not visible because it's folder is hidden should not get selected.

Thanks Mark

Good catch, you are correct, it should not get selected. I'll write this up today and send it in
