Wire electrical discharge machining (WEDM) is an unconventional process that being extensively used in the aerospace,medical devices, die, tooling, and automotive industries for high-hardness materials with conductivity. In present work, WEDM of aluminium 6082 alloys was carried out since it influences diversified applications manufacturing industries. The includes extensive number variables in...

The work presents a multi response optimization approach to determine the optimal process parameters in wire electrical discharge machining process. Experiments have been conducted using six process parameters such as discharge current, pulse duration, pulse frequency, wire speed, wire tension and dielectric flow rate each at three levels for obtaining the responses like material removal rate, ...

Whereas the efficiency of traditional cutting processes is limited by the mechanical properties of the processed material and the complexity of the workpiece geometry, electrical discharge machining (EDM) being a thermal erosion process, is subject to no such constraints. The base material used for this study was an AISI 1045 steel with copper electrode. This study highlights the development of...

Introduction: A bullet type sampler is sometimes used to obtain a sample from an asteroid on samplereturn missions [1]. On the other hand, in-situ analysis is demanded for the investigation of more amount of rock samples. Many drilling or coring devices have been developed [2-5]. Slicing the rock sample is preferable to observe its interior rather than shaving [6]. Because coolant cannot use in...

The process monitoring and mechanics of fixed abrasive diamond wire saw machining are investigated in this study. New techniques to affix diamond particles to a steel wire core have advanced to make this process feasible for the machining of ceramics, wood, and foam materials. Developments in fixed abrasive diamond wire machining are first reviewed. Advantages of using fixed abrasive diamond wi...

Electrical discharge machining (EDM) is the process of machining electrically conductive materials by using precisely controlled sparks that occur between an electrode and a work piece in the presence of a dielectric fluid. Aluminium metal matrix composites (AMMCs) refer to the class of light weight high performance aluminum ceramic material systems. The reinforcement in AMMCs could be in the f...

A review of the available literature on powder mixed electrical discharge machining (PMEDM) indicates that most research has been done for “die sinking mode” whereas “wire cut not received due attention despite being an important process variant. This work employs silicon carbide (SiC) dielectric fluid AISI D2 in cut” mode with re-circulating molybdenum wire (an economic and chemically stable p...

In conventional wire electrical discharge machining (WEDM), WC-Co machined pieces can stay for hours in the worktank. pH range of dielectric Co actively dissolves and thus corrosion occur affecting mechanical properties lifetime those pieces. This study demonstrates how applying cathodic polarization through implementation auxiliary electrodes work zone helps reducing in-depth propagation attac...
