**1. Introduction**

With the development and commercialization of micro-abrasive waterjet (μAWJ) technology, supported under an NSF SBIR Phase II/IIB grant, OMAX added a MicroMAX®to its product lines of JetMachining®Centers. In collaboration with MIT Center for Bits and Atom (CBA) and Department of Mechanical Engineering, the performance of abrasive waterjet (AWJ) was compared with those of lasers, wire EDM, and CNC milling [1–4]. Reference parts including miniature butterflies, tweezers, and nonlinear load cells were selected to cut with these tools. Based on their interesting performance comparison, a MicroCutting Project was initiated with the objective to broaden the performance comparison by including several selected sets of modern additive and subtractive machine tools.
