Good afternoon mates,
I created this angled. headstock model to use as my relief model.
It will be cut out of a 3x4" block, where I will cut out the side profile leaving a bit extra.
My question is since I have to set the material thickness to 3" it will simply be “in space” till it reached the actual wood.
Is there a hack I am missing, which toolpath works best?
Not sure I understand your question so maybe others who can help don’t understand it either.
Are the neck and head stock carved separately and then glued ?
Are the neck and head stock glued together and then carved. In which case, you wood block would look like this:
Thanks Chucky,
I cut it out of a solid 3x4 block which basically leaves what you have there.
I did try this:
I made a vector boundary, then made am Area Clearance toolpath, which I then projected onto the relief. It seems to work, I’ll do a test on some dense foam.
Maybe other guys have other ideas.
thanks,
William
That sketch above shows the wood stock before you start carving, not after.
If that’s the case, I don’t know how you deal with wood stock that is not the same depth throughout. I think you have to accept that you will have “air cuts” where your CAM software assumes you have wood but in reality, you don’t.
Hey William,
If I get this correct, you sorta kinda did rough shape on a bandsaw and want to carve out the profile with a 3d model, no?
For what I know about 3d model carving, you have a roughing toolpath and a finishing one. The finishing one does not look at the max dept of cut that is set for a bit, it assumes you did your roughing and carves the model. No air cutting.
You might be able to use a stirdy bowl bit to do a finish pass with a 30ish% stepover as a lets call it a rough finish and come in with your tapered or ballnose after that.
I have not tested such process for myself, just wildly theorizing here. This will need some serious testing before going for it on a real project.
Just a thought.
@William1 What do you have for CAD/CAM software to generate the toolpaths?
Hi Gwilki,
I use Plasicity for 3D design then import into Carveo Maker Plus, it allows vector projection.
Hi Eddie,
I’ll be gluing up 3-3/4" pdf to test.
Yes I rough it out within a 16th+, the width will not be touched so I can fasten it to the table with bridges.
I would already have the topside headstock angle done.
I can either do a 3D toolpath off the relief with some air cutting. LOL Or I can do an area clearance toolpath that I then project onto the model, Both allow for roughing and finishing.
I’ll post my progress and video it too.
Thanks,
William
