Wear Behavior in Wire of Wire Cut EDM

Applied Mechanics and Materials, 2014
Wire electrical discharge machining (WEDM) is a specialized thermal machining process, capable of accurately machining parts with different hardness, complex shapes and sharp edges that are very difficult to be machined by the traditional machining processes.

Micro-Wire-EDM

2018
Micro-wire-electro-discharge machining (micro-WEDM) is a widely used non-conventional micromachining process to fabricate three-dimensional (3D) complex micro-features in difficult-to-machine materials. This chapter offers a concise overview on the micro-WEDM process. A brief overview on the process mechanism, system components, parameters and variants

High-Precision Wire-EDM by Online Wire Positioning Control

CIRP Annals, 1994
The paper deals with a technical realization to improve the Wire EDM accuracy. The system which is readily available on commercial wire EDM machines is based on the on-line tracking and control of the wire position. The deviation of the wire position relative to the programmed wire path position is continuously measured and corrections are being made ...

Machining Characteristics of Inconel 718 by Sinking-EDM and Wire-EDM

Materials and Manufacturing Processes, 2014
Inconel 718 superalloy has wide applications in several industries due to its excellent mechanical properties. However, it is very difficult to machine using conventional cutting and grinding because of its high strength at elevated temperatures. Electrical discharge machining (EDM) is an alternative competitive process to machine Inconel alloys by ...

The Effect of Cutting Parameters on Wire Crater Sizes in Wire EDM

The International Journal of Advanced Manufacturing Technology, 2003
In this study, the effect of the cutting parameters on size of erosion craters (diameter and depth) on wire electrode were experimentally and theoretically investigated in wire electrical discharge machining (WEDM). The experiments were conducted under the different cutting parameters of pulse duration (300, 500, 700, and 900 ns), open circuit voltage (

Intricate ruled surface machining by wire-EDM

Journal of Materials Processing Technology, 1991
Abstract Based on the study of ruled surface (RS) mathematical modal, this paper introduces a new concept—distance parameter (DP) and puts forward that RS depends on not only two boundary curves but also DP. The formula to calculate the maximum inclination angle of ruling and the formula to calculate coordinates of points on ruled surface have been ...

Some Characteristics of Wire Electrode EDM

1980
The process of wire electrode EDM uses a travelling wire as a trepanning tool and represents an important development in EDM technology. In this paper the effects of the different variables of wire electrode EDM on process efficiency are studied without including numerical control considerations.

Analysis of electromagnetic force in wire-EDM

Precision Engineering, 2009
This paper clarifies the mechanism of how electromagnetic force applied to the wire electrode in wire electrical discharge machining (wire-EDM) is generated. This electromagnetic force is caused not only by DC component but also by AC components of the discharge current supplied to the wire.
