Electrical discharge machining (EDM) can use soft tool electrodes to process hard workpieces achieve “soft against hard”, because it directly uses electrical energy and thermal remove metal materials. Then, generate complex features on harder materials meet the requirements of excellent surface quality. Since EDM involves many parameters, including non-electrical properties, is essential optimi...

Electric discharge machining (EDM) is a type of high-precision usually applied to hard-material for mold manufacturing and in the aerospace industry. Longer process times typically reduce facility efficiency. The use electrochemistry (ECM) can overcome this challenge efficiently machine large workpieces. Some industries have adopted combined these two processes Inconel 718 material machining. H...

The electrical discharge machining (EDM) process is mostly used in conditions that complex and intricate shapes need to be machined on very hard metals. However, the leaves behind some undesirable properties such as high surface roughness, rough topography, residual tensile stresses, micro-cracks, heat-affected zone (HAZ), recast layer. This paper investigates effects of different output parame...

Preliminary notes This paper presents the possibilities of applying a new method of programming based on STEP-NC standards, which was developed as an alternative to the G code. The possibilities of application in the field of machining simulation and verification of the program before machining on the wire electrical discharge machine are discussed. The paper shows the possible methodology for ...

abstract: nowadays, the non-traditional processes such as “laser, edm and awj” used for cutting high thickness sheet metal. hardox is hard and tough steel alloy and it has many industrialize applications. one best process to cut the hardox is abrasive water jet (awj) cutting.  it can cuts complex shape with high quality and accurate tolerance.  awj cutting offers certain unique benefits such as...

In electrical discharge machining (EDM), gap control is the key to stable processing; plays a significant role in EDM. To determine influence of on material removal and melt pool movement, which are two fundamental issues EDM, high-speed photography molecular dynamics (MD) simulations were used study process. Research results demonstrate that has during A smaller width produces more larger remo...

Extensive work has been reported on modelling and optimization for different materials such as aluminum, iron, nickel-base alloy, C40 steel, mild steel, Ti6Al4V, HE15, 15CDV6, M-250, AISI D2 steel material etc. However model of process parameters for EDM technique on Ti-5Al-2.5Sn material has not been developed yet. Thus in the present work, an effort is made to develop model of material remova...

The reduction of electrode wear is very important for high finish and high accuracy machining in microEDM. Electrically conductive CVD diamond has shown almost zero electrode wear, even at short pulse duration of 3μs, which is extremely important for maintaining the desired shape. This research involves an investigation into the EDM performance of the electrically conductive CVD diamond with re...
