On the use of Copper Tool developed by Atomic Diffusion Additive Manufacturing (ADAM) Process for Electrical Discharge Machining

Abstract

This paper highlights the review of work done in the area of 3D printed tools for the spark machining process. In recent times, additive manufacturing has gained wide popularity in different sectors. The additive manufacturing process or 3D printing, is a method for creating three-dimensional objects by layering material. Using the additive manufacturing technique of atomic diffusion, a tool for electrical discharge machining was developed. In this method, a mixture of metal and polymer that are formed into wire was employed and kept in a cartridge. The material mix is deposited in similar to extrusion process. A computer software does all the calculation, costing, weight analysis and printing time assessment. The procedure of the same is discussed. The scanning electron microscopic analysis of the same is done along with porosity measurement using ImageJ software. The surface characteristics of the printed tool was measured with Gwyddion software. Discussion on applicability of printed tool for electrical discharge machining process is done. words.
