A dual ram assembly for a turret machine includes a first and second ram (140,150). The first ram comprises a first cam follower bracket (142) and a first set of cam followers (144). An outer die tooling (148) is connected to the first ram. The second ram comprises a second cam follower bracket (152) and second set of cam followers (154). An inner knockout tooling (158) is connected to the second ram. The first set of cam followers is configured to follow a first cam surface (170). The second set of cam followers is configured to follow a second cam surface (180). The first ram is connected to the second ram on a slide block. As the first and second sets of cam followers follow the first and second cam surfaces, the inner knockout tooling and the outer die tooling move toward or away from an article to be worked on.
