Hexblade positioner: A fast large-range six-axis motion stage

Here we introduce a new 6-axes positioner, called hexblade that achieves high speeds over large ranges with precision. The positioner these capabilities due to its bent-blade-flexure topology, which decouples 6 actuators. A matrix-based analytical approach is used model the stiffness and inertia of positioner's topology performance are subsequently calculated plotted for each version design comprehensive sweep geometric parameters. verified by comparing modal analysis results finite-element-analysis performed on same designs sampled from parameter sweep. An optimal fabricated frequency-sweep data provided (i) demonstrate design's open-loop dynamic in all 6° freedom (ii) experimentally validate approach. lowest eigenfrequency measured when stage driven extreme displacements directions system's support driving speed don't appreciably change as flexures deformed full range. Although introduced here designed enable rapid high-resolution 3D printing harsh, high-vibration environments (e.g., vibrating structure orbiting earth or inside fast-moving vehicle), suited any high-precision application requires motion along freedom. • We high-speed large-range 6-axis flexure-based precision stage. behavior. determine using FEA validated experimental measurements.
