ABSTRACT:
An apparatus and method for performing a sequence of machine operations on connecting rod blanks to convert the blanks from an original casting to a finished product includes loading parts at a beginning of a process stream for performing various machining operations on the parts as the parts travel along the process stream. The process stream is defined at least in part by a first path portion extending between opposing work stations for partially machining the parts, and recirculating the partially machined parts along the process stream into a second path portion. The second path portion extends parallel with the first path portion of the process stream in order to provide generally symmetrically opposing machining operations at the opposing work stations along a portion of the process stream. Lift and carry devices engage and move the raw parts and recirculating parts simultaneously between adjacent opposing work stations in step fashion. The raw parts and the recirculating parts are held in predetermined positions at each work stations within nests in cooperation with reciprocal holding devices to maintain the parts within the nests during the machining operations.
