Nb3Sn Wire Technology for High-field Superconducting Magnet

Nb3Sn superconducting wires are widely used for highfield superconducting magnets, and the NMR magnet is one of the most successful applications. In order to realize a large Jc (critical current density), which is essential to high-field superconducting magnets, several different types of production methods have been developed, such as the bronze-route method, the powderin-tube method and the i...

A Wear Investigation of Repeatedly Used Wire in Wire Cut Electrical Discharge Machine

Wire electro-discharge machining (WEDM) is a fully extended and competitive machining process widely used for hard and difficult to machine materials. In the present research, experimental investigation have been conducted to find out the wire wear rate at different machining parameter Such as peak current, pulse on time, pulse off time, based on full factorial design of experiment. Molybdenum ...

Optimization of machining parameters and wire vibration in wire electrical discharge machining process

Background: Wire Electrical discharge machining (WEDM) has higher capability for cutting complex shapes with high precision for very hard materials without using high cost of cutting tools. During the WEDM process, the wire behaves like a metal string, straightened by two axial pulling forces and deformed laterally by a sum of forces from the discharge process. Major forces acting on the wire c...

Breakdown of a Wire-to-Plane Discharge: Transient Effects

A wire-to-plane discharge during the early phases of breakdown has been studied. The discharge has been modeled in a prolate spheroidal coordinate system with the wire shape taken as a hyperboloid of revolution. Four simultaneous coupled, time-dependent, nonlinear partial differential equations describe the electrical discharge. These are the conservation equations for ion and electron densitie...
