WHAT IS CLAIMED IS:

1. A system for flexible manufacturing comprising:

a cell framework for defining a manufacturing area;

at least one workplace within the manufacturing area;

at least one manufacturing component within the manufacturing area and configured to be movable along multiple axes in relation to the at least one workplace; and

a conveying mechanism configured to move a part into the at least one workplace to be worked on by the at least one manufacturing component.

2. The system for flexible manufacturing according to claim 1 , wherein the manufacturing component comprises a press.

3. The system for flexible manufacturing according to claim 2, wherein the press is configured in a C-shape with pressing along a horizontal axis.

4. The system for flexible manufacturing according to claim 2, wherein the press comprises a tool exchanger mounted to the press, wherein the tool exchanger is configured to allow at least two tools to be alternatively mounted to the press, and wherein the tool exchanger is oriented with the press to allow the press to transmit a press force to the tool but not to the tool exchanger.

5. The system for flexible manufacturing according to claim 1 , wherein the manufacturing component is movable in relation to the workplace during a manufacturing cycle for accurate positioning.

6. The system for flexible manufacturing according to claim 1 , wherein the manufacturing component is movable in relation to the workplace during a manufacturing cycle for multiple operations.

7. The system for flexible manufacturing according to claim 1 , wherein the at least one workplace comprises at least two workplaces, wherein a first workplace is accessible to the at least one manufacturing component and a second workplace is accessible to an operator for manual operations, and wherein the system further comprises a pallet configured to be movable between the at least two workplaces.

8. The system for flexible manufacturing according to claim 1 , wherein the at least one manufacturing component comprises at least two manufacturing components, and wherein the at least one workplace and the at least two manufacturing components are each positioned and oriented in the manufacturing area to allow each of the at least two manufacturing components to operate on a part at the at least one workplace substantially simultaneously.

9. The system for flexible according to claim 1 , wherein the manufacturing area comprises a first manufacturing area, the system further comprises a second manufacturing area attached to the first manufacturing area in a modular fashion, the at least one workplace comprises a common workplace, and wherein the second manufacturing area is positioned and oriented to position the common workplace between the first and second manufacturing areas.

10. A system for flexible manufacturing comprising:

a cell framework defining a manufacturing area for completing an automated operation on at least one part, the cell framework having a base surface;

at least one workplace within the manufacturing area, wherein the workplace comprises a part fixture for receiving the part;

at least one machine press;

a moveable base supporting the machine press on the base surface; and

a positioning mechanism coupled to the moveable base for moving the machine press between: an operating position at the at least one workplace for completing the

automated operation on the part within the part fixture, and a standby position away from the part fixture.

11. The system according to claim 10, wherein the machine press comprises a C-shaped press having an actuation path, wherein the actuation path is aligned with the part fixture when the machine press is in the operating position, and wherein the actuation path is unobstructed by the part fixture when in the standby position.

12. The system according to claim 10, wherein the positioning mechanism cooperates with the moveable base to move the machine press along a plurality of mutually orthogonal axes in relation to the at least one workplace.

13. The system according to claim 12, wherein the positioning mechanism comprises an X-Y axis slide for moving the moveable base along the base surface, and a Z-axis slide for adjusting height of the machine press.

14. The system according to claim 10, wherein the machine press comprises a tool exchanger that is mounted to the machine press, wherein the tool exchanger comprises at least two tools and a rotatable turret for selectively positioning one of the at least two tools in alignment with the actuation path of the machine press.

15. The system according to claim 14, wherein the tool exchanger comprises a tool coupling, and wherein the tool exchanger is oriented with the press to allow the machine press to transmit a press force to one of the at least two tools via the tool coupling without transmitting the press force to the tool exchanger.

16. The system according to claim 10, wherein the machine press is movable to a plurality of operating positions in relation to the workplace during a manufacturing cycle for at least one of: accurate positioning of the machine press, and performance of multiple automated operations.

17. The system according to claim 10, wherein the at least one workplace is accessible to the machine press inside the cell framework to perform an automatic operation, and wherein the system further comprises:

at least one additional workplace accessible to an operator outside the cell framework to perform a manual operation;

wherein the fixture is moveable between the at least one workplace and the at least one additional workplace.

18. The system according to claim 17, wherein the at least one additional workplace is positioned outside the cell framework for completing the manual operation, and wherein the system further comprises a transfer receptacle at each workplace for moving the part fixture between the at least one workplace and the at least one additional workplace.

19. The system according to claim 10, wherein the manufacturing area comprises a first manufacturing area, the system further comprises a second manufacturing area attached to the first manufacturing area in a modular fashion, the at least one workplace comprises a common workplace, and wherein the second manufacturing area is positioned and oriented to position the common workplace between the first and second manufacturing areas.

20. A tool exchanger for use in a manufacturing component, the tool exchanger comprising:

a turret rotatably coupled to the manufacturing component, wherein the turret comprises:

a plurality of tool-mounting structures operatively connected to the turret;

a plurality of tool-couplings, wherein each of the plurality of tool- couplings is positioned and oriented within a respective tool-mounting structure to align, in sequence, each of the plurality of tool-couplings with an actuation path when the turret is rotated, wherein alignment of one of the

plurality of tool-couplings with the actuation path selects that one of the plurality of tool couplings; and

a tool-indexing servo coupled to the manufacturing component to rotate the turret relative to the housing;

wherein the turret is positioned within the actuation path wherein:

movement of a mounted tool along the actuation path to a first position couples the mounted tool to the selected tool-coupling and configures the tool- exchanger in an operation mode; and

movement of the mounted tool along the actuation path to a second position decouples the mounted tool from the selected tool coupling and configures the tool-exchanger in an indexing mode.
