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

Abstract

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 overcut comes from the discharge between the processing debris and the side wall of the target structure. Furthermore, by applying the textured cutting tool, the target square structure is directly fabricated on the alumina workpiece with just a simple turning process, which verifies the feasibility of the proposed tool cutting edge textured method by applying the WEDM. This technology is expected to become a potential method for the mass production of micro structure surfaces in the future.

Ultrasonic-Assisted Incremental Microforming of Thin Shell Pyramids of Metallic Foil

“…For this purpose, efficient microprocessing technologies with high accuracy and high surface quality are required to meet the demand for their production. Microcutting [ 1 ], micro-laser-machining [ 2 ], micro-electric discharge machining [ 3 , 4 ], and microforming [ 5 ] have been intensively studied, and recently, micro-additive-manufacturing combined with other microprocessing [ 6 ] is more and more important in tailor-made manufacturing or high-mix low-volume production of complex parts.…”

Properties Evaluation of Thin Microhardened Surface Layer of Tool Steel after Wire EDM

“…In general, achievable qualitative parameters of eroded surface are comparable to the parameters achieved by finishing machining technologies [1,2] such as grinding, honing, lapping, superfinishing, etc. However, a complex evaluation of machined surface quality after WEDM is a demanding procedure.…”
