“…Effectiveness of cryogenic machining in reducing tool wear, cutting force and surface quality of the work piece is already proven in experiments [8][9][10][11]. These experiments showed thatcryogenic machining is superior in comparison to MQL and dry machining.…”

“…Uncoated carbide has a very different surface texture from coated carbide, mainly because the coating layer helps to make the tool harder and tougher with a good surface finish. The residual stress which is present on the machine surface is improved, along with reducing the cutting temperature and enhancing the machine surface with the help of the coating layer (Outeiro, Pina, M'Saoubi, Pusavec, & Jawahir, 2008). It was observed that the compressive stresses increase with increase of the thermal softening of the material and such surface flaws clear out of the machined surface, enabling the near-surface area of the workpiece to reconstruct itself easily (Kadirgama, Abou-El-Hossein, Mohammad, Noor, & Sapuan, 2008).…”

This paper presents an experimental study of surface integrity in end milling of Hastelloy C-2000. The experiment was carried out using two different cutting inserts under wet conditions -namely physical vapor deposition coated carbide with TiAlN and uncoated carbide. Design of experiment was implemented with a Box-Behnken design. The surface integrity of the workpiece was analyzed through scanning electron microscopy (SEM) and chemical element changes were inspected by an energy dispersive X-ray (EDX) test. The surface integrity of Hastelloy C-2000 was better when machining with coated carbide compared to uncoated carbide cutting inserts, mainly because the coating layer of coated carbide acted as a protecting layer to the cutting tool insert. Surface defects such as feed marks, surface tearing, plucking, cracking and adhered chips were found during the machining process. The chemical element changes happened due to the adhesion and diffusion mechanisms which were identified using SEM and EDX.

“…Carbide cutting tools are amongst the oldest of the hard cutting tools. The use of coated and uncoated tungsten carbide (WC) cutting tools is seen to offer control over the residual stress, because the coated WC cutting tool enhances the residual field on the machined workpiece, reducing the cutting temperature when machining nickel-based alloy [27][28][29]. However, it was still observed that uncoated tools reach higher maximum process temperatures than coated tools [27,30].…”

This paper presents an experimental study of the cutting force and chip formation in the end milling of the nickel-based superalloy, Hastelloy C-2000. The experiment was conducted using two different cutting inserts under wet conditions -namely physical vapor deposition coated with TiAlN, and uncoated carbide. The assessment of machining performance is based on a design of experiment. New insight into the influence of the cutting process on the cutting force and chip formation are key measures of machining performance. The effect of the machining parameters on chip formation was examined through scanning electron microscope micrographs and energy dispersive x-ray tests. The cutting forces and chip formation analysis for different sets of experiments were examined and compared in order to establish the most suitable cutting conditions, through highlighting the drawbacks and by suggesting proper measures to be undertaken during machining performance, which might overcome the barriers of machining Hastelloy C-2000.
