Gear fabrication in wire electrical discharge machining (WEDM) plays an important role manufacturing industries. This paper describes the analysis and optimization of process parameters for spur gear on brass workpiece (10cmx15cmx6mm) material by EDM process. The experiments were performed using design experiment (DoE) approach removal rate (MRR) was analyzed response surface methodology techni...

Abstract There are a variety of uses for metal matrix composites (MMC), including the aerospace and automotive industries. Because their benefits light weight inexpensive cost, they popular. Wire cut electric discharge machining (WEDM) stands out as great option creating complex or complicated shapes composite materials, especially when compared to other common non-traditional processes. An AA6...

Fatigue performance is a major consideration for critical aerospace components. The influence of surface grinding and rough/finish wire electrical discharge machining (WEDM) on the high cycle fatigue binary Ti 50.8 -Ni 49.2 shape memory alloy was assessed. effect machined workpiece integrity in terms roughness subsurface microhardness results also evaluated, addition to fractography analysis. T...

Advanced ceramic materials are gradually becoming very important for their superior properties such as high hardness, wear resistance, chemical resistance, and high strength to weight ratio. But machining of advanced ceramic like Al2O3-ceramics is very difficult by any well known and common machining processes. Normally, cleavages and triangular fractures generate when machining of these materi...

Wire-EDM is a highly complex process, which is characterized by non-linear behavior. Owing to unique capabilities of machining complex shapes and hard materials with high accuracy and fine surface finish, WEDM is used in various manufacturing industries. There has been on-going research to develop automated capabilities for WEDM by understanding the interaction mechanism of various input parame...

Increasing the machining efficiency of middle speed wire electrical discharge (MS-WEDM) is usually through optimizing process parameters, but servo parameters controller can also be optimized to achieve same purpose. This paper develops a multi-mode for MS-WEDM investigate parameters. Firstly, structure and control principle are introduced, core functions described in detail. Secondly, it intro...

An ultrasonic vibration has been superposed on the normal electrode movement to increase the flushing effect during a micro electro-discharge machining (EDM) process. A systematic study on the effects of ultrasonic vibration on the EDM performance for fabricating microholes in Nitinol has been completed. The introduction of ultrasonic vibration to the microEDM process has more than 60 times inc...
