Special Issue Information

Dear Colleagues,

Research in the field of machining is constantly progressing, and one primary area of interest is the precise and efficient machining of simple and complex parts for various industries. The effect machining of various types of materials is currently advancing the field, with various methods being employed to correctly select suitable machining strategies, perform measurements and verifiy the required shape and dimensions of parts. The machining process requires the achievement of high precision and quality in the production of parts, which is a common goal in satisfaction of customer requirements. This Special Issue aims to present application solutions that relate to machining processes, control methods and additive manufacturing. These new solutions should ultimately enable mechanical engineers to achieve efficient production and high precision. I would like to invite you to contribute a manuscript to this Special Issue, whose scope includes, but is not limited to, the following topics:

  • Machining of metallic and non-metallic materials;
  • New technologies and methods in the machining process;
  • Coatings and their applications in the field of cutting tools;
  • The wear and lifetime of cutting tools;
  • Lubricants and their influence;
  • High-speed milling;
  • Vibrations and their effect on the quality of the machined surface;
  • Evaluation of the integrity of the machined surface;
  • Hard-to-machine materials;
  • Dimensional and shape accuracy of parts manufactured by milling;
  • The micro and macro geometry of cutting tools;
  • Milling strategies;
  • CAD/CAM systems;
  • Machining of parts created via metal additive manufacturing.

Abstract
Inconel 617 is a nickel-based superalloy that is a primary candidate for use in next-generation nuclear applications such as the Gen IV Molten Salt Reactor (MSR) and Very-High-Temperature Reactor (VHTR) due to its corrosion and oxidation resistance and high strength in elevated temperatures.

Inconel 617 is a nickel-based superalloy that is a primary candidate for use in next-generation nuclear applications such as the Gen IV Molten Salt Reactor (MSR) and Very-High-Temperature Reactor (VHTR) due to its corrosion and oxidation resistance and high strength in elevated temperatures. However, Inconel 617 machinability is poor due to its hardness and tendency to work harden during manufacturing. While the machinability of its sister grade, Inconel 718, has been widely studied and understood due to its applications in aerospace, there is a lack of knowledge regarding the behaviour of Inconel 617 in machining. To address this gap, this paper investigates the influence of cutting parameters in the turning of Inconel 617 and compares the impact of Minimum Quantity Lubrication (MQL) turning against conventional coolant. This investigation was performed through three distinct studies: Study A compared the performance of commercial coatings, Study B investigated the influence of cutting parameters on the surface finish, and Study C compared the performance of MQL to flood coolant. This work demonstrated that AlTiN coatings performed the best and doubled the tool life of a standard tungsten carbide insert compared to its uncoated form. Additionally, the feed rate had the largest impact on the surface roughness, especially at high feeds, with the best surface quality found at the lowest feed rate of 0.075 mm/rev. The utilization of MQL had mixed results compared to a conventional flood coolant in the machining of Inconel 617. Surface finish was improved as high as 47% under MQL conditions compared to the flood coolant; however, work hardening at the surface was also shown to increase by 10–20%. Understanding this, it is possible that MQL can completely remove the need for a conventional coolant in the machining of Inconel 617 components for the manufacturing of next-generation reactors.
