Wire-EDMing Parameters Investigation and Machining Cost Analysis
International Journal of Knowledge and Systems Science, 2022Cost analysis of wire-EDMing operation was investigated in this study. Servo voltage, pulse on time, pulse off time, wire feed rate, and wire tension were varied in the experiment to define the optimal conditions for supporting wire-EDMing process. Taguchi's L27 orthogonal array was applied for designing the experiment. Machining cost, material removal

CNC Automatic Programming System for Wire-EDM
1999This paper introduces a developed CAM system for wire-EDM to automatically select the sequencing of the wire path considering fixation stability. The system creates technological aspects based on geometry features. Many of the wire cutting techniques such as trim cut, correction, taper angle, threading & breaking points, and the standard radius are ...

Prevention of wire breakage in wire EDM
International Journal of Machining and Machinability of Materials, 2011This paper compares the performance of brass wire and zinc-coated wire on wire electro discharge machining (EDM) of high speed steel (HSS) material. For both types of wire the current, duty cycle, pulse-on time and wire speed have been selected as the input variables while the cutting rate, surface roughness and frequency of wire breakage as the output

Investigation of silicon wafering by wire EDM
Journal of Materials Science, 1992The new technology of silicon wafering by wire electrodischarge machining (EDM) was investigated to determine its mechanism of current-conducting and material removal. Target materials were n-type single-crystal silicon ingots with the resistivity of 7–15 cmΩ. It was found that the surface potential barrier of the semiconductors had a dominating effect

NC verification for wire-EDM using an R-map
Computer-Aided Design, 1996Abstract Due to the high complexity and the low speed of the wire-EDM process, it is important to recognize all the possible errors before starting the process. The unproductive and time consuming test runs of wire-EDM NC programs in the real production environment can be avoided by computer graphic simulation.

Roughness of the machined surface in wire EDM
Russian Engineering Research, 2016Wire electric-discharge machining (EDM) is investigated. A complete factorial experiment is conducted. Regression methods are used in analysis of the experimental results and the derivation of an empirical formula. The empirical model obtained permits assessment of how the roughness of the machined surface depends on the cutting conditions, the height ...
