“…In terms of machining properties, life of cutting tools deteriorates due to the work hardening and attrition properties of Inconel 718. Furthermore, very high cutting forces cause metallurgical damage to the workpiece, such as work hardening, surface tearing, and distortion (Madariaga et al 2014;Sofuoğlu et al 2018a;Sofuoğlu et al 2018b). xx/xx 02/10…”

This paper investigates the influences of three different input parameters, such as feed rate, insert nose radius, and insert coating methods, in the turning operation of Inconel 718. The coating methods were selected as medium temperature chemical vapor deposition (MT-CVD) and physical vapor deposition (PVD) and in addition to coating methods, the role of various coating materials was discussed since the inserts were coated with multi-layers of TiCN/Al2O3/TiN and single-layer of TiAlN on carbide substrates. The results were discussed in terms of wear behavior of cutting tools and surface quality of the workpiece, which is indicated by surface roughness. A full factorial experimental design was employed in the present work and the results were evaluated using main effects plots. Furthermore, the analysis of variance (ANOVA) method was applied to specify both reactive and non-reactive effects of experimental parameter reactions. The results showed that surface roughness is reduced using low feed rates and large nosed inserts in the operations. Furthermore, TiAlN-coated inserts with PVD method provided better surface finish than with MT-CVD method. It was also found that surface roughness increases as the wear rate of inserts increases.

“…The experimentation results showed that the abrasiveness of the carbide particles on the tool and the mechanical loading had a growing influence on the CF. Sofuo glu et al [5] studied the impact of the v c , tool extended length, and novel methods, namely Conventional Turning (CT), Ultrasonic Assisted Turning (UAT) and Hot-Ultrasonic Assisted Turning (HUAT) on the SR, a p , and CT while machining Hastelloy X. The reduction in SR and increment in regular a p and CT were attained in UAT and HUAT compared to CT. Dhananchezian [6] conducted the machinability study on Hastelloy C-276 under dry and cryogenic liquid nitrogen (LN 2 ) cooling conditions using turning operation.…”

In this research work, the machinability of turning Hastelloy X with a PVD Ti-Al-N coated insert tool in dry, wet, and cryogenic machining environments is investigated. The machinability indices namely cutting force (CF), surface roughness (SR), and cutting temperature (CT) are studied for the different set of input process parameters such as cutting speed, feed rate, and machining environment, through the experiments conducted as per L27 orthogonal array. Minitab 17 is used to create quadratic Multiple Linear Regression Models (MLRM) based on the association between turning parameters and machineability indices. The Moth-Flame Optimization (MFO) algorithm is proposed in this work to identify the optimal set of turning parameters through the MLRM models, in view of minimizing the machinability indices. Three case studies by considering individual machinability indices, a combination of dual indices, and a combination of all three indices, are performed. The suggested MFO algorithm’s effectiveness is evaluated in comparison to the findings of Genetic, Grass-Hooper, Grey-Wolf, and Particle Swarm Optimization algorithms. From the results, it is identified that the MFO algorithm outperformed the others. In addition, a confirmation experiment is conducted to verify the results of the MFO algorithm’s optimal combination of turning parameters.

“…In recent years, many scholars have carried out many corresponding studies on ultrasonic assisted processing, ultrasonic assisted machining is a new composite machining method [10]. Ultrasonic assisted cutting increases the periodic vibration in one or more directions on the basis of ordinary cutting, periodic contact and separation between tool and workpiece, periodic changes in velocity magnitude and direction, so that the processing process can achieve better results [11]. Wang et al [12] performed ultrasonic milling tests on Vit1 block metallic glass, the results showed that compared with ordinary milling, the milling force in the feed direction of ultrasonic assisted milling was reduced by an average of 23%, and the axial resistance was reduced by an average of 31%, the tool wear was also significantly improved.…”

Carbon fiber reinforced plastics (CFRP) is a new type of composite material that is widely used in the aviation field, the influence mechanism of fiber cutting angle on cutting force is analyzed, a theoretical model of ultrasonic assisted cutting force for CFRP is established, ultrasonic assisted longitudinal-torsional cutting experiments of CFRP disc are carried out, and compared with normal cutting process. According to the experimental results, the radar map of the cutting force along the circumference of CFRP unidirectional laminates is established, which show that the cutting force can be reduced by ultrasonic assisted cutting compared with ordinary cutting. Under the three cutting modes, the fiber cutting angle has a great influence on the tangential force, and the radial force of the same fiber cutting angle is less than the tangential force, the maximum radial force appeared near the fiber cutting angle of 120°, while the minimum tangential force and the minimum radial force both appear near the parallel direction cutting at 0°. The research results can be used for reference in the processing of CFRP and other composite materials.
