Investigation of Micro Square Structure Fabrication by Applying Textured Cutting Tool in WEDM

This paper studies micro structure fabrication by means of a textured tool cutting edge, which is manufactured by applying the wire cut electrical discharge machining (WEDM). Machining performance of the square structure fabrication on the tool cutting edge is investigated in the WEDM process, and the machining accuracy is explored in experimental analyses. In this proposed method, undesired ov...

An Algorithm to Generate Cutting Path for Micro-Fabrication

In a two-photon femtosecond laser system of three-dimensional micro-fabrication, a model of micro-device is fabricated layer by layer along its contours of cross-sections. So it is necessary to generate cutting path. In this paper, we present an efficient algorithm to generate cutting path which is a series of ordered contour points on each cross-section of a model. Keyword. Micro-fabrication, ...

Design and Fabrication of the Harvard Ambulatory Micro-Robot

Here we present the design and fabrication of a 90mg hexapedal microrobot with overall footprint dimensions of 17 mm long x 23 mm wide. Utilizing smart composite microstructure fabrication techniques, we combine composite materials and polymers to form articulated structures that assemble into an eight degree of freedom robot. Using thin foil shape memory alloy actuators and inspiration from bi...
