2. The apparatus of claim 1 , wherein the first position adjustment mechanism comprises a spindle and wherein the first flexure member is a flexure rod, the flexure rod coupled to the spindle.
3. The apparatus of claim 2 , wherein the first flexure rod has a thread and the spindle has a thread receiver, and wherein the first flexure rod is coupled to the spindle using the thread and thread receiver.
4. The apparatus of claim 3 , wherein the first position adjustment mechanism further comprises a motor coupled to the spindle to rotate the spindle.
5. The apparatus of claim 4 , wherein the motor comprises a worm reduction gear.
6. The apparatus of claim 1 , further comprising:
a target coupled to the first die;
a second die; and
a sensor coupled to the second die to determine the position of the first die with respect to the target.
7. The apparatus of claim 1 , further comprising:
a thrust pad coupled to the first die through a gas bearing during an initial range of travel of the thrust pad.
8. The apparatus of claim 7 , further comprising:
a thrust rod pivotally coupled to the thrust pad, the thrust rod comprising a gas inlet and a vacuum ring outlet.
9. The apparatus of claim 8 , wherein the gas inlet is configured to direct gas between a gas bearing surface of the thrust rod and the first die.
10. The apparatus of claim 7 , further comprising:
a bell crank coupled to the thrust rod; and
a bladder actuator coupled to the bell crank using a toggle link.
11. The apparatus of claim 1 , further comprising a second flexure member coupled to the first die.
12. The apparatus of claim 11 , further comprising a second position adjustment mechanism to adjust the position of the first die along a third axis.
13. The apparatus of claim 12 , wherein the first and second flexure members are flexure rods and wherein the first position adjustment mechanism comprises:
a first spindle coupled to the first flexure rod; and
a first motor coupled to the first spindle to rotate the first spindle; and
wherein the second position adjustment mechanism comprises:
a second spindle coupled to the second flexure rod; and
a second motor coupled to the second spindle to rotate the second spindle.
14. The apparatus of claim 13 , wherein each of the first flexure rod and the second flexure rod has a thread, wherein each of the first spindle and the second spindle has a first thread receiver, the thread and the thread receiver to couple a respective flexure rod with a respective spindle.
15. The apparatus of claim 14 , wherein each of the first and second motors comprises a worm reduction gear.
16. The apparatus of claim 12 , wherein the first axis is substantially perpendicular to the third axis.
17. The apparatus of claim 16 , further comprising a single thrust rod configured to apply a force to the first die along the second axis, wherein each of the first axis and the third axis lie in a same plane being substantially perpendicular to second axis.
18. The apparatus of claim 1 , wherein the positional adjustment mechanism is coupled to the first flexure member to adjust the position of the first die along a third axis.
19. The apparatus of claim 18 , wherein the first flexure member is a blade.
20. The apparatus of claim 19 , wherein the positional adjustment mechanism comprises a first axis slide coupled to the first flexure member and a third axis slide.
21. The apparatus of claim 20 , wherein the positional adjustment mechanism further comprises:
a first motor coupled to the first slide to adjust the position of the first die along the first axis; and
a second motor coupled to the third axis slide to adjust the position of the first die along the third axis.
22. The apparatus of claim 21 , wherein the first motor and the second motor are a same motor.
23. An apparatus, comprising:
a die coupled to a first flexure member;
means for aligning the die with a surface along a first axis using the first flexure member;
means for pressing the die; and
means for maintaining contact between the die and the first flexure member during the pressing.
24. The apparatus of claim 23 , further comprising means for aligning the die with the surface along a second axis using the first flexure member.
25. The apparatus of claim 23 , further comprising means for aligning the die with the surface along a second axis using a second flexure member.
26. The apparatus of claim 25 , further comprising means for maintaining contact between the die and the second flexure member during the pressing.
27. The apparatus of claim 25 , further comprising means for moving the die in a direction substantially perpendicular to the first and second axes using a single thrust rod.
