“…Similarly, Chou et al [29] examined the tool performance based on the surface roughness and tool flank wear Bartarya et al [9] show the cutting condition and the range of each parameter used by various researchers in hard turning and this review shows that the range of feed rate chosen is between 0.05-0.2 mm/rev. In summary, it was realized that most of the researches used almost similar or the same cutting conditions by neglecting the ongoing developments on the machine tool and cutting tool technology and thereby discarding the wisdom of having chosen tighter limits of feed rate.…”

“…Consequently, surface residual stresses, the appearance of a white layer resulting in surface deterioration and attainable surface roughness have given only partial success to the commercialization of HT. Therefore, several attempts were made by the researchers in the past to study the possibilities of solving some of these aspects by different approaches, such as [6][7][8][9]:…”

Abstract:Continuous research endeavors on hard turning (HT), both on machine tools and cutting tools, have made the previously reported daunting limits easily attainable in the modern scenario. This presents an opportunity for a systematic investigation on finding the current attainable limits of hard turning using a CNC turret lathe. Accordingly, this study aims to contribute to the existing literature by providing the latest experimental results of hard turning of AISI 4340 steel (69 HRC) using a CBN cutting tool. An orthogonal array was developed using a set of judiciously chosen cutting parameters. Subsequently, the longitudinal turning trials were carried out in accordance with a welldesigned full factorial-based Taguchi matrix. The speculation indeed proved correct as a mirror finished optical quality machined surface (an average surface roughness value of 45 nm) was achieved by the conventional cutting method. Furthermore, Signal-to-noise (S/N) ratio analysis, Analysis of variance (ANOVA), and Multiple regression analysis were carried out on the experimental datasets to assert the dominance of each machining variable in dictating the machined surface roughness and to optimize the machining parameters. One of the key findings was that when feed rate during hard turning approaches very low (about 0.02mm/rev), it could alone be most significant (99.16%) parameter in influencing the machined surface roughness (Ra). This has, however also been shown that low feed rate results in high tool wear, so the selection of machining parameters for carrying out hard turning must be governed by a trade-off between the cost and quality considerations.

“…For the CBN tools used in hard turning, the preparation of the edge radius on the cutting tool is critical for both tool performance and quality of the machined component [12]. Variation of the edge radius may influence on chip formation, minimum chip thickness, cutting forces, tool wear, and tool life, as shown in Fig.…”

Performance of cutting tool in hard turning is significantly influenced by its microgeometry, such as edge radius. This study presents an experimental exploration to understand the effect of cutting edge radius on machining performance in terms of surface roughness and tool wear. The cutting tools (CBN) with three groups of nominal edge radius, 20, 30, and 40 μm, were used in the study. The cutting edge radii were characterized with an Alicona optical microscope, and variation of the edge radius was evaluated in this study. The machining tests were then conducted to experimentally assess the effect of cutting edge radius on surface quality and tool wear under different machining conditions. Three-level and two-factor experiments were designed in the test. The results in this study suggest that there is noticeable variation in the edge radius on a cutting tool with a certain nominal value of edge radius. The variations tend to be smaller with increase of the nominal value of edge radius. Besides, the results can be drawn that edge radii have a significant influence on surface roughness and tool wear. Considering all factors, the cutting tool with nominal edge radius of 30 μm demonstrate better machining performance among three groups of cutting tool in hard turning of AISI52100 steel.

“…El desgaste del flanco de la herramienta de corte fue medido con un microscopio electrónico de barrido marca JEOL. La utilización de elevadas velocidades de corte provoca un aumento de la temperatura en la herramienta de corte, como consecuencia debilita la arista de corte [10]. Los insertos de corte muestran desgaste por abrasión, adhesión, difusión y fractura del borde cortante, similar resultado obtenido por Jianxin y otros [11].…”

<p>El presente estudio experimental se centra en determinar modelos estadísticos para predecir el desgaste del flanco durante el torneado en seco del acero inoxidable AISI 316L utilizando dos insertos de corte. Los parámetros de corte fueron comparados utilizando un análisis de varianza y de regresión múltiple. Como principales resultados se obtuvieron el efecto significativo del avance de corte y el tiempo principal en el desgaste del flanco. Se hallaron los modelos estadísticos para estimar el desgaste de flanco, así como los errores absolutos medios de cada ecuación. El mejor desempeño correspondió al inserto GC2015 según las ecuaciones de regresión.</p>
