Complex 4th axis deburing tool path.

[NicholasO123]

Hello, I'm trying to machine a part on my multi axis live tool lathe. The part is round with varying diameters that transition into each other. I'm trying to debur a slot on the part. The bottom of the slot machines  well with 2d contour wrapping.  However the top of the part has varying Z heights as it twists around the part. The problem that I'm having is every tool path that I've tried just wants to follow a cylinder and not the change of Z. In other words it will only stick to the same Z height. I have the machining extension. I need a tool path that is like trace but for 4th axis to break/chamfer the edge.

Hi

Luckily For You there is a toolpath called Deburr which will do what you want.

It has 3, 4 and 5 axis modes

If you have a y axis you can set the primary mode to "zero lead angle" for the best results

If you don't have a Y axis you would need to set it to "To Rotary axis"

Your toolpath is treating the part as a simple cylindrical wrap, so it’s ignoring the changing Z along the twist. The fix is to extract or project the true 3D edge curve, then run a swarf or flow toolpath directly along that curve. This lets the path follow both the twist and the Z variation. Just make sure the tool orientation follows the curve so it doesn’t flatten out. A screenshot of the edge would help pinpoint the best method.

This the part I'm working with. I have made the slots successfully. The radius edges are not needed, only a chamfer/edge break. I do have a Y axis. I have been unsuccessful at debur tool path, but hopefully I can tweak it somehow. Here is the section of the part.

Hi

Deburr will not deburr edges that don't exist in the model.

If you delete the Radii from the model then it should work just fine.

If your still unsuccessful, you can Upload the model here and we can show you how to do it.

Goto File>Export>Save as .f3d/.f3z
