Fabrication of high-quality microflexures using micromilling techniques
This research focuses on the feasibility of using micromilling as a process for fabricating the flexural body of mesoscale nanopositioners. A desire to fabricate non-silicon microflexures for more favorable material properties and flexural responses has led MIT's Precision Compliant Systems lab to …

Analysis and comparison of metrology methods for quantifying micro-endmills
Micromilling is a powerful machining method increasingly used in the medical, optical, and electronics industries to rapidly create 3-dimensional, micro-scale components for meso-scale devices. The micromilling process causes higher incidences of tool wear and breakage, which are often not readily …
