Threading using wrapped toolpaths help?

[77_JR]

Hi everyone.

I'm trying to use the 4th axis to thread on the mill, I know there are better ways but I'm just experimenting with the 4th axis at the mo for practice.

Is there a way to do multiple roughing depths with a 60 degree cutter? I think the issue is because the multiple depths option is not available with spot/chamfer mills, but here must be a way. I've also tried a pocketing operation but this ramps down with the Z continuously throughout the operation, which I want to avoid.

Hi

You will have to create duplicate operations and offset the bottom height each time to make multiple steps with that tool.

You can also use tangential extensions to get the path to machine right off the end correctly

There's another option defining the tool as a tapered mill

see video and file for explanation

Thanks mate!! I’ve learnt a lot from them two demonstrations.

There is also an option called passes and linking on the cutting data inside the tool settings that called ”stepdown” but I wasn’t having having much luck getting this to respond much.

maybe it’s for something else..

anyway, I’m going to test the way you have shown soon as I can 🙂

The Stepdown and stepover in the tool library are for autopopulating some of the fields in operations

Like optimal load and stepdown in adaptive:

or 2D contour:

I really only use them in presets for roughing

Ahhh like presets. Thats worth knowing. Cheers.
