Abstract
A platform for constraining a workpiece includes x-y stage connected to a base, wherein the x-y stage includes a floor and a y-axis datum and a x-axis datum aligned along a first axis and a second axis perpendicular to the first axis, respectively, and a primary constraint mechanism on the x-y stage. The primary constraint mechanism includes an x-axis wedge, a primary y-axis wedge and a primary z-axis clamp, and a primary linear actuator with a rod extendable and retractable parallel to the second axis. A primary linear actuator slides the x-axis wedge away from the x-axis datum, slides the primary y-axis wedge away from the y-axis datum, and rotates the primary z-axis clamp away from the workpiece. The primary z-axis clamp is attached to a cam with a pinion gear that engages a rack gear connected to the rod of the primary linear actuator.
