Micro electrochemical milling

Journal of Micromechanics and Microengineering, 2004
In this paper, electrochemical machining (ECM) for fabricating micro structures is presented. By applying ultra short pulses, dissolution of a workpiece can be restricted to the region very close to an electrode. Using this method, 3D micro structures were machined on stainless steel.

Micro milling characteristics of LS-WEDM fabricated helical and corrugated micro end mill

International Journal of Mechanical Sciences, 2020
Abstract Micro milling offers a high potential for fabricating three-dimensional micro structure, such as micro grooves, micro channels and micro dimples. However, the fabrication of solid micro end mills with hard materials and complex structures poses many challenges.

Diamond milling of micro-optics

IEEE Aerospace and Electronic Systems Magazine, 2006
A diamond mill (a tiny end mill) can cut aspheric lenses and mirrors with diameters smaller than 0.5 mm. The cutting tool has a two-dimensional shape and is spun about the axis of the surface to be cut. As the spinning tool is plunged into the substrate, it cuts a radially symmetric surface to sub-micron accuracies.

Micro-EDM Milling of Micro Compressor Prototype

First International Conference on Integration and Commercialization of Micro and Nanosystems, Parts A and B, 2007
Micro power system is becoming more and more important for micro- and nano-scale system. The fast development of MEMS (Micro Electromechanical Systems) has strongly enhanced the application of new harder work materials. The fabrication of metallic 3D microstructures has been one of the most attractive topics of micro machining.

Micro-EDM Milling of Micro Platinum Hemisphere

2006 1st IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2006
Micro-EDM milling has become one of the powerful means of 3D micromachining for MEMS. However, for micro- EDM milling, there isn't a general electrode wear compensation strategy matched to arbitrary materials of workpiece and electrode. In this paper, the machinability of platinum metal is evaluated by taking latent heat of fusion and evaporation into ...

Machining NiTi micro-parts by micro-milling

Materials Science and Engineering: A, 2008
Abstract The machinability of NiTi by milling has been examined using solid carbide end milling cutters. First results were obtained from machining simple slots applying TiAlN-coated tools with a diameter of 0.4 mm. The machining process was evaluated in terms of tool wear, cutting forces and machining quality.

Fabrication of Complex Micro Channels by Micro Electric Discharge Milling (µ-ED Milling)

Volume 2B: Advanced Manufacturing, 2013
Micro electric discharge milling (μ-ED milling) is an effective and economic process for the fabrication of micro channels. In the present work, the bulk approach of μ-ED milling is being attempted to make complex shaped micro channels. For a straight channel the bulk approach of μ-ED milling was found to be a successful approach.
