Re: CAD: Making a cam mechanism

I also tried making this cam in pro-e which my result was okay but not perfect maybe if I had spent more than 10 mins on it....



anyway the question I have for you is how critical is the cam to have a follow cam profile? You could just use a cylinder piece of stock and drill the rotation hole offset from the center and get a cam effect. If you use a 3in piece and drill it .5 in off center you will get the same extreme's that you are looking for.

I guess I am wondering if the quick transition is actually necessary.
