Abstract:
A method of fabricating a cross-blade flexure block, comprising the steps of:furnishing a first plate of a flexure material; machining a first cross-blade flexure element from the first plate as a first single piece of material; furnishing a second plate of the flexure material; machining a second cross-blade flexure element from the second plate as a second single piece of material; wherein each of the cross-blade flexure elements comprises: an upper blade housing; a lower blade housing positioned with respect to the upper blade housing such that there is a planar slot between the upper blade housing and the lower blade housing and lying in a slot plane, the upper blade housing and the lower blade housing being shaped to define an external form factor symmetric about a housing axis and a bore therethrough symmetric about the housing axis; and a blade extending transversely through the bore between the upper housing and the lower housing and intercepting the housing axis, the blade having a blade angle of from more than 0 to less than 90 degrees relative to the slot plane; and assembling the first cross-blade flexure element and the second cross-blade flexure element together to form a flexure block.
