Cylindrical Cam Segment - back and forward

[Anonymous]

Hello. I'm using Inventor 2012 and need to design a Cylindrical Cam Segment - it's a back and forward system instead of a continuous movement like a regular cam. I've tried emboss, bend, sweep and design accelerator without sucess. 

target - make follower (a cylinder) follow the path - up if cam is turned clockwise and down if turned otherside. i've also read these threads, but no solutions yet.

I haven't looked at your file, but -

I suspect you could simply create a cylindrical cam using the Design Accelerator that goes the entire 360° and then Sculpt to fill the unwanted portion.

greetings, JDMather.

I've done what you said, but I'm not been able to constrain the roller to path. Whem I use transitional, followers goes straight top cylinder. 

Mesuring Cam (supposibly to be 20mm width), I've found 19,999 and 19,994mm widths. 

Any suggestions on how can I constraind cam and follower?

thank you,
