Due to the abrasive nature of material, conventional machining CFRP composites is typically characterised by high mechanical forces and poor tool life, which can have a detrimental effect on workpiece surface quality, properties, dimensional accuracy, and, ultimately, functional performance. The present paper details an experimental investigation assess feasibility wire electrical discharge (WE...

This paper presents the mechanical design and experimental characterization of a 2-DOF serial flexurebased micropositioning table. The cascade mechanical structure is proposed to implement planar motions of the moving platform. In order to increase the stroke of the moving platform, a lever mechanism is designed to amplify the displacement of the piezoelectric actuator. The finite element metho...

Electroconductive, homogeneous and dense ceramic/semiconductor/metal nanocomposites were obtained by hot press and subsequently machined by wire Electrical Discharge Machining (EDM). The addition of semiconductor and metal phases to a highperformance ceramic material produces nanocomposites which preserve the excellent mechanical properties of the ceramic/metal material while reaching the elect...

correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

Tribological characteristics of fine-grained WC–8 wt%Ni with different surface finishing conditions corresponding to sequential wire electrical discharge machining (wire-EDM) or grinding were investigated by performing dry reciprocating sliding experiments on TE77 pin-on-plate equipment with WC–6 wt%Co as mating material. Surface finishes and wear surfaces were characterized using surface topog...
