In one embodiment, a method for controlling a manufacturing process can include obstructing a part receiving path of a press station with a part detection fixture. The part detection fixture can include a moveable contact member and a target body that moves in response to motion of the moveable contact member. The moveable contact member of the part detection fixture can obstruct the part receiving path such that the target body of the part detection fixture is positioned in a dissenting state. The target body of the part detection fixture can be positioned in an assenting state coincident with contact between the moveable contact member of the part detection fixture and the workpiece. Image data of the target body of the part detection fixture can be detected with a vision system. The press station can be actuated when the image data is indicative of the assenting state.
