Claim 0:
1. A ram drive assembly for a can bodymaker including a plurality of forming assemblies, each forming assembly including: a stationary assembly and a moving assembly, the stationary assembly including a die pack, the moving assembly including a ram assembly and a cam follower assembly, the die pack defining an elongated forming passage having a proximal end and a distal end, the ram assembly including an elongated ram body having a proximal end and a distal end, the cam follower assembly coupled to the proximal end of the ram body, the ram body structured to reciprocate through the forming passage of the die pack between a retracted, first position, wherein the distal end of the ram body is spaced from the proximal end of the die pack, and, an extended, second position wherein the distal end of the ram body is extended from the distal end of the die pack, the ram drive assembly comprising:
a cam having a body with a number of cooperative cam surfaces structured to operatively engage the cam follower assembly of each forming assembly of the plurality of forming assemblies; and
a motor having a rotating output shaft operatively coupled to said cam body and structured to rotate said cam body,
wherein the cam body is a disk cam or a barrel cam, and
wherein the number of cooperative cam surfaces are portions of a ridge extending from the cam body.
