Cam design

#1

Anyone know of software to design sine cams? For example y=sin (x) and another would be y=sin (2x) cams of that nature.

Thanks :slight_smile:

Bonus point if you guess what I want to make :smiley:

Might just be polar graphing r=sin (t) …

If you can figure out the proper equation then you can “design” in processing or javascript (with a plugin like 3.js).

If you have Solidworks then it will graph equations (see @Hirudin’s work in the divider thread).
I have seen a demo of this, but it 'aint cheap https://www.psmotion.com/

Search for modified sine curve cam.
Perhaps this can help about cam design. Also. Check out the portfolios at processing.org. The math and images are very helpful.

Thanks :slight_smile: I’ll check the sites out.

openSCAD can likely do that without a problem since it is algorithm driven…

Thanks!

It’s free of course, just to warn the learning curve is a tad steep (since it is essentially a programming environment rather than visual cad). However if you are asking about sine-cams, you already likely know what you are doing…

I think I may have “missed the mark” somewhat. :slight_smile:
