What is Micromachining?

Mechanical Micromachining Micromilling, Microdrilling An emerging micro-

manufacturing technique Machining features with

characteristic dimensions less than 1 mm (0.040 in) Usually less than 500 micron (0.020 in) in diameter

(tools in milling and drilling)

Energy Systems Would smaller ones makes sense in

terms of efficiency? Specific Challenge

Large-area micro-featured structures (e.g., stamping and rolling dies)

Ideas for Meeting the Challenge Systems approach to micro-manufacturing
