Prediction of Electrochemical Machining Process Parameters using Artificial Neural Networks

Electrochemical machining (ECM) is a non-traditional machining process used mainly to cut hard or difficult to cut metals, where the application of a more traditional process is not convenient. It offers several special advantages including higher machining rate, better precision and control, and a wider range of materials that can be machined. A suitable selection of machining parameters for t...

Parametric Analysis of Electrochemical Discharge Micro-Machining Process during Profile Generation on Glass

Electrochemical discharge micro-machining (micro-ECDM) has the ability to machine electrically nonconducting materials as compared with different existing traditional and also non-traditional machining processes. This paper deals with the effects of different process parameters like applied voltage (V), electrolyte concentrations(wt%), pulse frequency and duty ratio on different machining perfo...

Quadrilateral Micro-Hole Array Machining on Invar Thin Film: Wet Etching and Electrochemical Fusion Machining

Ultra-precision products which contain a micro-hole array have recently shown remarkable demand growth in many fields, especially in the semiconductor and display industries. Photoresist etching and electrochemical machining are widely known as precision methods for machining micro-holes with no residual stress and lower surface roughness on the fabricated products. The Invar shadow masks used ...

Diffusion Process for GGR Machining System with Spares, Balking and Reneging (RESEARCH NOTE)

This paper deals with the G/G/R machining system consisting of M operating machines as well as S cold standbys. The concepts of balking and reneging are incorporated which make our model more versatile to deal with real time systems. The broken-down machines are sent to repair facilities consisting of R permanent repairmen. The failure times and repair times are generally identical and independ...
