... features pertaining different wear mechanism displayed during turning of waspaloy. The methodology used to distinguish the contributing elements was developed coupling turning tests with corresponding tribological experiments so that clear evidences on different contributions were identified showing...

.... This study explores the effect of micro-texture geometry parameters fabricated on the rake face of tungsten carbide inserts that were tested in dry turning titanium alloy Ti-6Al-4V. The effects of micro-texture geometry on the cutting forces, tool stresses, tool temperatures, tool wear rate, and variable...

... is expected to exhibit stronger adaptability since it achieves greater flexibility. In this paper, an active chatter suppression strategy is presented by simultaneously adjusting the amplitude and frequency of spindle speed variation. The effect of SSV parameters on stability improvement in turning processes...

...Dinh Nguyen; Phi-Ho Lee; Yang Guo; Kyung-Hee Park; Patrick Kwon This paper evaluates the performances of dry, minimum quantity lubrication (MQL), and MQL with nanofluid conditions in turning of the most common titanium (Ti) alloy, Ti-6Al-4 V, in a solution treated and aged (STA) microstructure...

... i where a i , and k i are power-curve fit coefficients at the end of each pass i ( i  = 1–3). This paper served to analyze the effect of two different carbide grain sizes on the VTW of straight WC-Co inserts when turning Ti–6Al–4V. By adapting a previously developed...

...M. Eynian; Y. Altintas The accurate prediction of chatter stability in general turning operations requires the inclusion of tool geometry and cutting conditions. This paper presents regenerative chip and regenerative chip area/cutting edge contact length based dynamic cutting force models, which...

... feeder system is shown in Fig. 1 , and the photograph of the setup for the turning equipment is shown in Fig. 2 . The solid lubricant powder feeder system is comprised of five components: the solid lubricant feeder, shaft, helical blades, the single-phase induction motor, and the casing...

...Takashi Ueda; Akira Hosokawa; Keiji Yamada In this paper, the influence of oil mist on the tool temperature in cutting is investigated experimentally. The turning of a carbon steel with oil mist applied is performed, and the temperature of the alumina tool at the tool-chip interface is measured...
