Fabrication and Characterization of Cross-Connected Microchannel Porous Mesh Plates (CCMPMPs) by Multi-Cutter Milling.

A new method for fabricating CCMPMPs, namely multi-cutter milling, is proposed and the fabrication principle is discussed. Then, a study of three microchannel parameters, the microchannel depthHc, widthWc, and intervalWs, and two CCMPMP parameters, the porosityPand the total surface area per unit volumeSV, is presented. Furthermore, 3D FEM has been adopted to study the effective stress distribution, the metal flow velocity distribution, and the cutting forces. The results show that CCMPMPs can be successfully machined.Hc,Wc, andWscan be controlled by the radial depth of cutae, the slotting cutter thicknessEt, and the gasket thicknessEg, whilePandSVcan be changed by adjustingHc,Wc, andWs. Moreover, asaeincreases, the average resultant force increases, and the friction between chip and the side face of the machined microchannel, and between chip and the rake face, plays an increasingly important role in it.
