Barrel Cam Relationship

[aldug]

Has anyone found a way to mate a barrel cam to a cam follower mounted on a linear slide in an assembly so as you rotate the cam, the follower moves linearly?

Hi,

yes, it works. The cam itself must, however, have closed set of tangent faces to define the cam. When the follower's mating
face is a flat one the rotation of the cam may stop at arbitrary
positions. What SE version are you running?

I can get it to work fine with plate cams, it's barrel cams that I'm at a loss with.

Hi,

hmm, 'barrel cams' -- tells me nothing at the mo. Shape like
those on a car's camshaft?

/Edit

got it! I think it can't be done with that relationship.
Might be something for either Motion or the new Motor function
in V19. But I've not done that so I cn't help any further.

Hi,


just made a quick test: it will work with the new (V19) Gear
Relationship --> rotation to linear

it just haunted me ;-)

That also doesn't quite do what I want. This is an illustration of what I have:

As I rotate the cam, I want the follower to stay inside of the groove and slide back and forth.
