I think I have an idea of your explination of a cam grinder.
Am i correct in saying that it works somewhat similar to a key copying machine?
But instead of cutting flat keys, the stock it is rotated on one side which is directly connected to another part of the machine that, when turns causes the cam portion to rotate under the grinder.
With an eccentric to cause the grinder to "rise" and "fall" onto the stock you are grinding.
How do you design the geometry of the eccentric to cut the journal?
Super cool stuff !!!!!
I guess that after you design the eccentric all you got to do is flip 180 degrees for intake and exhaut. |
