Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Machinability investigation of S32750 super duplex stainless steel using magnetorheological fluid-assisted nano polished cemented carbide tool inserts   Order a copy of this article
    by Thiyagu M, Elanchezhian J, Anbuchezhiyan G, Narendranathan SK, Purushothaman P 
    Abstract: This study explores nano-polishing of cemented carbide tool inserts with magnetorheological fluid (MRF) and diamond abrasives to enhance tribological properties in the tool chip contact zone. The MRF-assisted process yielded surface roughness under 30 nm on the flank and under 48 nm on the rake face. When used for dry turning of S32750 super duplex stainless steel, these nano-finished inserts extended tool life by up to 30%, with an average life of 27 minutes compared to 19 minutes for unprocessed inserts. This resulted in an 18% reduction in cutting forces and improved lubricity, outperforming conventional inserts in terms of cutting force, flank wear, and surface roughness.

  • Influence of high magnetic field on surface roughness and temperature of Inconel 718 in dry turning operation with SiAlON ceramic cutting tool.   Order a copy of this article
    by Sukhdev B. Waghmode, Anupama N. Kallol, Rajendra L. Doiphode, Deepak M. Shinde 
    Abstract: In this research work, the high magnetic field is applied on a single-point silicon aluminium oxynitride (SiAlON) ceramic cutting tool during the turning process of Inconel 718 (In718) to check its effect on surface roughness, tool temperature, and tool wear at different cutting speeds. A Neodymium magnet is used to apply the magnetic field. The machining parameters selected for experimentations are speed 5 levels and magnetic field 11 levels. In the experiment, Lorentz force is developed which helps for improvement of surface roughness. The experimental results showed that tool marks caused by the tool vibration are highly reduced, resulting in improvements in surface roughness. Moreover, because of the magnetic field fine particles are removed from the cutting zone resulting in decreased tool wear. Magnetic field affected on thermal conductivity of In718 which causes tool temperature is decreased but in the case without magnetic field machining temperature is increased as speed increases.
    Keywords: Inconel 718; turning; magnetic field; surface roughness; tool wear.

  • Experimental Investigation and FEA Implementation on Drilling of Graphene Reinforced GF/epoxy Polymer nano Composite Laminate using Coated and Uncoated Carbide Drills.   Order a copy of this article
    by Bishnu Prasad Mishra, Debadutta Mishra, Pranabini Panda, Pragyan Senapati, Trupti Ranjan Mahapatra 
    Abstract: The current study aims to explore the drilling characteristics of graphene-reinforced GF/epoxy nanocomposites via experimentation, validated by finite element analysis (FEA). Experiments involved drilling a [0/90]40s 10 mm thick laminate using 8 mm diameter uncoated and coated (TiN, TiAlN) solid carbide drills (2 flute, cone angle: 118?). Effects of coating, cutting speed, and feed rate on thrust force, torque, entry, and exit hole size were analysed. Uncoated drills exhibited the highest average thrust force (78.6 N) and torque (0.61 Nm) compared to TiAlN and TiN coated drills. TiAlN produced maximum average value of thrust force and torque of 48.4 N and 0.44 Nm, while TiN yielded maximum average value of thrust force and torque of 44.70 N and 0.35 Nm, respectively. Uncoated drills showed 27%
