Fabrication of Hemispherical Tool Tip of Ultra Small Diameter via Electrode Wear Phenomenon in EDM

Tool wear studies in fabrication of microchannels in ultrasonic micromachining.

Form accuracy of a machined component is one of the performance indicators of a machining process. Ultrasonic micromachining is one such process in which the form accuracy of the micromachined component significantly depends upon the form stability of tool. Unlike macromachining, a very small amount of tool wear in micromachining could lead to considerable changes in the form accuracy of the ma...

An Experimental Study of Surface Roughness of H11 Steel in Edm Process Using Copper Tool Electrode

In this study, the effect of input parameters of Electro Discharge Machining (EDM) process including polarity, peak current, pulse on time, duty cycle, gap voltage and concentration of abrasives powder in dielectric fluid on surface roughness are experimentally investigated. A L18 Taguchi’s standard orthogonal array is used for experimental design. Copper is used as tool electrode to machine H1...

Edm of Tool Steel

The EDM Vis Tool

We introduce EDM Vis, an information visualization software tool for exploring, navigating and understanding student data logs. EDM Vis loads student logs, entire classes, hundreds of students, at a time, and displays the student behavior of those students as they solved problems using a software tutor. The visualization uses a tree structure to provide an overview of class performance, and int...

A Fast Inspection of Tool Electrode and Drilling Depth in EDM Drilling by Detection Line Algorithm

The purpose of this study was to develop a novel measurement method using a machine vision system. Besides using image processing techniques, the proposed system employs a detection line algorithm that detects the tool electrode length and drilling depth of a workpiece accurately and effectively. Different boundaries of areas on the tool electrode are defined: a baseline between base and normal...
