“…However, cutting force is one of the most important parameters which reflect the tool wear degree directly for the high-speed milling of Inconel 718 curved surface. 24,25 To further increase the productivity of Inconel 718, there is an urgent need for further research on the wear mechanism of coated cutting tool with different geometrical parameters.

High-speed machining provides an efficient approach for machining Inconel 718 with high quality and high efficiency. For high-speed milling of Inconel 718 curved surface, the geometrical characteristics are changing continuously leading to a sharp fluctuation of cutting force, which will aggravate the tool wear. As the wear mechanism of coated cutting tool is seriously affected by the cutting tool geometrical parameters, suitable geometrical parameters of cutting tool should be selected to avoid the cutting tool from being worn out very quickly. In this study, the influence of cutting tool geometrical parameters on tool wear in high-speed milling of Inconel 718 curved surface is investigated with coated cutting tool, and the cutting force in milling process is also analyzed. The results show that the cutting force variation can manifest the tool wear degree, and the failure type of coated cutting tool in plane milling and curved surface milling after the same cutting length is different. Furthermore, the cutting tool geometrical parameters seriously affect the tool wear and the tool life in high-speed milling of Inconel 718 curved surface. Concretely, the small rake angle has greater strength and has superiority, the relief angle increasing can enhance the tool life, and the tool life is decreased with the increasing of helix angle for the cutting tool, whose helix angle is larger than 30°. This study provides a theoretical basis for cutting tool wear mechanism and cutting tool geometrical parameter selection in high-speed milling of Inconel 718 curved surface, so as to guarantee the machining efficiency in high-speed milling of Inconel 718 curved surface.

A mastering of surface quality issues during machining helps avoiding failure, enhances component integrity and reduces overall costs. Surface roughness significantly affects the quality performance of finished components. A number of parameters, both material and process oriented, influence at a different extend the surface quality of the finished product. Aluminium alloy 5083 component surface quality, achieved in side end milling, constitutes the subject of the present case study. The design of experiment method is employed: that is, 18 carbide two-flute end mill cutters -manufactured by a five-axis grinding machine -have been assigned to mill 18 pockets in finishing conditions -having different combinations of geometry and cutting parameters values, according to the L 18 (2 1 3 3 7 ) standard orthogonal array. Process performance is estimated using the statistical surface texture parameters R a , R y and R z -measured during three different passes on the side surface of the pockets. The results indicate that process parameters -such as the cutting speed, the peripheral second relief angle and the core diameter -mostly influence surface texture. The experimental values are used to train a feed forward back-propagation artificial neural network for the prediction of the yield surface roughness magnitude.

“…Due to the characteristics of side milling, axial force F z usually keeps a relatively small value and it has minor effects on the total cutting forces. 21,22 Thus, we will first focus on the feed force F x and radial force F y , respectively, when side milling Inconel 182 overlays.…”

Nuclear steam turbines are well-known working in saturated wet-steam environment. The use of anti-corrosion material depositing or coating on the critical components and then machining to the required thickness with specific surface quality can be an effective and economical way to prevent critical components of steam turbines from corrosion and erosion. Inconel 182 can be this anti-corrosion material; however, a few literature has reported its machinability, not to mention its machinability at different overlay thickness. The objective of this study is to investigate the influence of the coated overlay thickness on microstructures and machinability of Inconel 182 overlays. First, the micro-hardness and microstructures of Inconel 182 overlays at different overlay thickness are studied. Afterwards, cutting forces, cutting temperature, surface roughness and the machined surface morphology at different overlay thickness are discussed. Finally, the prediction model for machining Inconel 182 overlays at different overlay thickness is established. The results indicate that the microstructures of Inconel 182 overlays strongly rely on overlays thickness and Inconel 182 electrode diameter (3.2 mm). The prediction model illustrates that the machinability of Inconel 182 overlays is acceptable at overlay thickness from about 0 to 2.1 mm; it is poor at overlay thickness from about 2.1 to 6.4 mm, and it is stable at overlay thickness from about 6.4 to 10 mm.
