Cylindrical Sweep
Cylindrical Sweep
(OP)
Goal:
Cyclindrical cam, barrel cam, drum cam, however you want to call it.
Trying to make a slot radially on a cylinder.
My approach:
Extrude the cylinder
Sketch slot path on a plane tangent to the cylinder
insert-curve-projection - project sketch onto cylinder surface
Sketch sweep profile on a plane that is normal to the curve.
Initial prototype is made on cnc lathe with live tooling to cut that radial cams/slot. or vmc with 4th axis.
Sweep cut with sketch and projected curve.
Errors/issues...
No matter what options I choose, the profile still twists along the path. The closest I have gotten is to "counter-twist" by twisting appx 10deg so it "looks" like it
doesn't twist.
Guide curves are tricky and have only given me more problems.
I get a lot of intersecting profiles until i tweak the profile.
Any tips/suggestions, approaches? Thanks!

Is this different than "swept boss/base" and "cut-sweep"?
RE: Cylindrical Sweep
I believe it is still an approximation, but is much closer to reality.

I think I've solved my sweep problem. Waiting for swept solid.

I personally am not going to recommend this feature because so many people are going to try and use it for something its not ready for and this is the initial release of the command. So its in it's infancy stages.
Good luck!
