The objective of the present work was to investigate the effect of the wire electrical discharge machining process parameters on material removal rate of titanium alloy using Taguchi approach. A brass wire of 250μm was applied as a tool electrode to cut the specimen. L36 mixed orthogonal array (2 ×3) has been selected for experimentation under different variables like dielectric conductivity, p...

Based on notes by Elizabeth Ellinger, Spring 2004, as expanded and modified by Bruce E. Trumbo, 2005-08. Copyright © 2005, 2008 by Bruce E. Trumbo. All rights reserved. 8.1.1. For your convenience the breaking strength measurements in the table above have been repeated below, reading across each row of the table. Put them into c1 of a Minitab worksheet; label it PSI. Then use the patterned data...

The main objective of this work is to develop a mathematical model to evaluate optimum sanding conditions of Europen black pine (Pinus nigra). Samples were sanded using different of grit size, feed rate, cutting speed and depth of cut. Average surface roughness (Ra) values of each type of specimens were measured employing a stylus type of equipment. Interaction between sanding parameters and su...

The experimental investigations of the delamination factor of glass fiber reinforced plastic at different cutting parameters are reported in this study. This paper has involved the determination of different factors affecting the hole quality and cause of delamination in a glass fiber reinforced plastic. The various process parameters like different twist drill bits of different materails, diff...

Every day scientists are developing new materials and for each new material, we need economical and efficient machining. Turning process is the one of the methods to remove material from cylindrical and non-cylindrical parts. Stainless steel is a widely used material in day to day applications. This paper deals with the optimization of turning process by the effects of machining parameters appl...

The article analyzes the operational reliability of filter on gas turbine compressor intake and electric transformer connector. Empirical data (statistical sample) were collected to determine failure density function f (t), hazard λ expected value mean time MTTF. numerical model was created in Minitab 19 software tool. Anderson-Darling test used accept or reject hypothesis.

Awan cumulonimbus merupakan jenis awan berbahaya yang dapat menimbulkan cuaca ekstrim seperti hujan deras, kilat dan guruh. Jenis angin mempengaruhi adanya adalah Vertical wind shear, dengan ini menentukan badai terjadi. Apakah termasuk kedalam intensitas hebat atau tidak. Karena semakin besar shear akan juga terjadi akibat cumulonimbus. Untuk mengetahui keterkaitan pada pertumbuhan maka diadak...
