“…That means, the experimental study exhibits a close relation between flank wear and surface roughness. Similar findings are reported in the literature (Fnides et al 2008;Bouchelaghem et al 2010). However, surface roughness shows a gradual deterioration with increase in tool VB, surface roughness and tool wear does not exceed the control criterion of hard turning process (i.e.…”

Background: Now-a-days, newer hardened steel materials are coming rapidly into the market due to its wide applications in various fields of engineering. So the machinability investigation of these steel materials is one of the prime concern for practicing engineers, prior to actual machining. Methods: The present study addresses surface roughness, flank wear and chip morphology during dry hard turning of AISI 4340 steel (49 HRC) using CVD (TiN/TiCN/Al 2 O 3 /TiN) multilayer coated carbide tool. Three factors (cutting speed, feed and depth of cut) and three-level factorial experiment designs with Taguchi's L 9 Orthogonal array (OA) and statistical analysis of variance (ANOVA) were performed to investigate the consequent effect of these cutting parameters on the tool and workpiece in terms of flank wear and surface roughness. For better understanding of the cutting process, surface topography of machined workpieces, wear mechanisms of worn coated carbide tool and chip morphology of generated chips were observed by scanning electron microscope (SEM). Consequently, multiple regression analysis was adopted to develop mathematical model for each response, along with various diagnostic tests were performed to check the validity and efficacy of the proposed model. Finally, to justify the economical feasibility of coated carbide tool in hard turning application, a cost analysis was performed based on Gilbert's approach by evaluating the tool life under optimized cutting condition (suggested by response optimization technique).

“…Furthermore, the same material may have different degrees of machinability by adding some specific chemical elements such as tellurium (Yaguchi & Onodera, 1988). As a result, there are many interacting parameters responsible for improving different machinability aspects including tool life, cutting force, surface finish and formation of small and stable built-up edges (Bouchelaghem et al, 2010;Kishawy et al, 2012;Peruchi et al, 2014;Song & Zuo, 2014;Xu et al, 2012). In all machining processes, including turning, controlling the workpiece-tool interaction associated with the workpiece material is extremely difficult, especially when combining these parameters to study their effects on machinability and/or surface characteristics and their impact on service life (Costa et al, 2016;Fnides et al, 2011).…”

In this study, several series of experiments on turning process of AISI 12L14 free cutting steel characterized by its self-lubrication and the high percentage of lead in its composition were performed to rate the influence of cutting conditions (Vc, f and ap) on the machining performance such as surface roughness, cutting force, cutting power and material removal rate. A computer generated optimal design of experiment based on the I-optimality criteria along with analysis of variance was created to study the characterizations in turning of this steel, and desirability function was utilized for the optimization. The global optimization, combined high surface quality and productivity with low cutting power consumption, gave 12 optimal setting points provided high desirability values. The obtained correlation for surface roughness, cutting force, material removal rate and cutting power were 99.4%, 95.5%, 99.7% and 94.3%, respectively.

“…Compared to grinding operations, precision hard turning enabled relatively high material removal rate and flexibility and thus, became more attractive especially to automotive, bearing and hydraulic industries [1][2][3]. Huang et al presented a thorough review that discusses CBN tool material microstructure, encountered wear patterns and tool wear rate modeling under hard turning [4].…”

Modeling and optimization of hard turning of X38CrMoV5-1 steel with CBN tool: Machining parameters effects on flank wear and surface roughness

The present study, aims to investigate, under turning conditions of hardened AISI H11 (X38CrMoV5-1), the effects of cutting parameters on flank wear (VB) and surface roughness (Ra) using CBN tool. The machining experiments are conducted based on the response surface methodology (RSM). Combined effects of three cutting parameters, namely cutting speed, feed rate and cutting time on the two performance outputs (i.e. VB and Ra), are explored employing the analysis of variance (ANOVA). Optimal cutting conditions for each performance level are established and the relationship between the variables and the technological parameters is determined using a quadratic regression model. The results show that the flank wear is influenced principally by the cutting time and in the second level by the cutting speed. Also, it is that indicated that the feed rate is the dominant factor affecting workpiece surface roughness.
