The control system is designed to control a hydraulic press having a die, at least two separate sets of workpiece forming punches, and at least two hydraulic pistons, each operatively associated with one set of workpiece-forming punches. The control system includes a means for controlling a magnitude of a pressing force applied by each set of workpiece-forming punches, and a means for controlling a position of each set of workpiece-forming punches relative to the die. ## Claims ### Claim 1 A powder press manufacturing system comprising; an independent power source for delivering hydraulic fluid with a pressure; a plurality of pressing modules remotely associated therewith, each said pressing module comprised of at least one punch having an end for pressing a powder material to form a work piece, the at least one punch being operatively associated with a first end of a piston having a second force receiving end; at least one hydraulic assembly configured to apply pressing force directly to the force receiving end; the plurality of pressing modules being operatively and reciprocally connected to and receiving power through the delivery of the hydraulic fluid from the independent power source; a die to receive and contain the powder, the die having an opening position to receive the end of the punch; and at least one controller associated with each of the pressing modules, the controller for controlling the pressure of the hydraulic fluid being delivered by the independent power source to the module. ### Claim 2 (depends on 1) The manufacturing system according to claim 1, wherein the pressing module further comprises means for delivering powder into the die and creating a substantially uniform distribution of powder in the die. ### Claim 3 (depends on 1) The manufacturing system according to claim 1, further comprising at least one pressing station remotely connected to the power source, wherein each of the at least one pressing module is removably attached respectively at one of the at least one pressing station. ### Claim 4 (depends on 2) The manufacturing system according to claim 2, wherein the means for creating a substantially uniform distribution comprises a powder fluidizing apparatus. ### Claim 5 (depends on 1) The manufacturing system according to claim 1, further comprising a computer interface associated with that controller. ### Claim 6 (depends on 1) The manufacturing system of claim 1, wherein the punch being operatively associated with said first end of the at least one piston is removable therefrom. ### Claim 7 (depends on 1) The manufacturing system of claim 1, wherein the punch being operatively associated with the first end of the at least one piston comprises a single monolithic part. ### Claim 8 (depends on 1) The manufacturing system of claim 1, further comprising at least one second punch extending a second direction opposite that of the at least one first punch and towards the die. ### Claim 9 (depends on 8) The manufacturing system of claim 8, wherein, the at least one second punch is fixed. ### Claim 10 (depends on 8) The manufacturing system of claim 8, wherein the at least one second punch is operatively associated with a first end of at least one second piston having a second force receiving end. ### Claim 11 (depends on 1) The manufacturing system of claim 1, wherein the first piston moves toward and into the due until it moves a predetermined distance in the cylinder. ### Claim 12 (depends on 1) The manufacturing system of claim 1, wherein the first piston moves toward the die until a predetermined force is being applied to a first surface of the work piece. ### Claim 13 (depends on 1) The manufacturing system according to claim 1, wherein the first piston moves toward and into the die until a mechanical stop is reached. ### Claim 14 A modular manufacturing system comprising; an independent power source for delivering hydraulic fluid with a pressure; a plurality of manufacturing modules remotely associated therewith, each of the manufacturing modules comprised of at least one tool having an end for working a material to form a work piece, the at least one tool being operatively associated with a first end of a piston having a second force receiving end; at least one hydraulic assembly configured to apply pressing force directly to the force receiving end; said manufacturing modules being operatively and reciprocally connected to and receiving power through the delivery of hydraulic fluid from said independent power source; a die to receive and contain the material, the die to engage the end of the punch; and at least one controller associated with each of pressing modules, the controller for controlling the pressure of the hydraulic fluid being delivered by the independent power source to the module. ### Claim 15 (depends on 14) The manufacturing system according to claim 14, wherein the Manufacturing module further comprises means for delivering the material to the die and creating a substantially uniform distribution of the material in the die. ### Claim 16 (depends on 14) The manufacturing system according to claim 14, further comprising at least one manufacturing station remotely connected to the power source, wherein each of said at least one manufacturing module is removably attached respectively at one of the at least one manufacturing station. ### Claim 17 (depends on 14) The manufacturing system according to claim 14, further comprising a computer interface associated with that controller. ### Claim 18 (depends on 14) The manufacturing system according to claim 14, wherein said tool is configured as a stamp. ### Claim 19 (depends on 14) The manufacturing system according to claim 14, wherein the tool is configured as a forging press. ### Claim 20 (depends on 14) The manufacturing system according to claim 14, wherein said tool is configured as a closed mold for casting fluid material. ### Claim 21 (depends on 14) The modular manufacturing assembly according to claim 14, wherein said tool is configured as a closed die for receiving casting material. ### Claim 22 A press for forming a work piece, comprising: an independent power source for delivering hydraulic fluid with a pressure;
