    Modeling of 3D temperature fields for oblique machining
    (Elsevier, 2012) N/A; Department of Mechanical Engineering; N/A; Lazoğlu, İsmail; İslam, Coşkun; Faculty Member; Master Student; Department of Mechanical Engineering; Manufacturing and Automation Research Center (MARC); College of Engineering; Graduate School of Sciences and Engineering; 179391; N/A
    Fast and accurate temperature prediction for oblique cutting processes is still one of the most complex problems and challenges in the machining research community. For the first time in this article, a novel 3D temperature prediction model based on the finite difference approach for oblique cutting processes is presented. An elliptic structural grid generation method is implemented. Representing different oblique cutting geometries is straightforward now. Moreover, since the resulting equation system is algebraic, the model allows much faster calculations compared to available finite element method based machining temperature models. 3D oblique simulation results verify that temperatures are in good agreement with experimental results.

    Titanium is a commonly used material in various critical applications such as aerospace and biomedical applications. In this article, for the first time in the literature, development and implementation of a novel plasma boronizing process on Tungsten Carbide (WC) cutting tools is introduced. Plasma boronizing on WC tools is performed with gas combination of 10% BF3, 40% Argon and 50% H-2 at different temperatures and durations. Performance enhancements of plasma boronized WC tools on Titanium (Ti-6Al-4V) machining are investigated under various cutting conditions. It is found that new plasma boronizing of WC is a very cost effective solution for significantly increasing tool life in Titanium machining. (C) 2010 CIRP.
