Article history: Received January 2, 2015 Received in revised format 6 February 2015 Accepted 15 February 2015 Available online February 17 2015 Surface roughness and cutting forces are considered as important factors to determine machinability rate and the quality of product. A number of factors like cutting speed, feed rate, depth of cutting and tool noise radius influence the surface roughne...

In the metal cutting process, the friction and wear behavior between the cutting tool and machined surface is the most important factor that affects the surface quality and the service life of the cutter. The irregular pore structure of porous titanium alloy has changed its mechanical properties and the processing technology. The friction and wear mechanism of the cutting tool and the machined ...

In this study, two different vegetable based cutting fluids developed from refined canola and sunflower oil and a commercial type semi-synthetic cutting fluid were carried out to determine optimum conditions for tool wear and forces during milling of AISI 304 austenitic stainless steel. Taguchi L9 (3) orthogonal array was used for the experiment plan. Cutting speed, feed rate, depth of cut and ...

ISBN 978-93-82338-21-5 | © 2012 Bonfring Abstract--The present paper is an experimental study to investigate the effect of cutting parameters (cutting speed, depth of cut and feed) on tool wear, surface roughness and material removal rate (MRR) during dry turning of EN-31 steel. Turning experiments were conducted with cutting speeds: 250, 300, 350 m/min, feeds: 0.15, 0.2, 0.25 mm/rev and depth ...

Nowadays, application of cermet coatings deposited by High-Velocity Oxygen-Fuel (HVOF) has received considerable attention in a variety of industries. Carbide coatings have high surface roughness, so it is essential to grind the coated surface. The present investigation studied the effect of simultaneous changes in the grinding parameters including the depth of cut, feed rate and cutting sp...
