Summary: Nickel-based superalloys, such as INCONEL (R) variants, are increasingly used in various industries due to their high-temperature resistance and resistance to creep. However, they are considered difficult-to-cut materials because of their poor thermal conductivity and work hardening, which can lead to tool wear and poor finishing. Therefore, optimizing machining parameters is crucial for improving the quality and cost of the product.

Summary: Inconel 718 is highly valued in aerospace and nuclear industries, but machining this material is difficult due to rapid tool wear. In this study, turning experiments were conducted to evaluate the machinability of Inconel 718 using PCBN tools with different binder phases. It was found that cutting speeds and workpiece properties significantly influenced tool life, with notch wear being a major concern at lower speeds and flank wear at higher speeds. Tools with TiN-based binder outperformed TiC-based tools, exhibiting more consistent behavior during machining.

Summary: This paper summarizes the drilling and milling processes in Fiber Metal Laminates (FMLs) based on a literature review from 2000 to 2023. It analyzes and discusses the parameters used in multi-material manufacturing and machining, as well as the machining process parameters related to sustainability. SWOT analysis identifies opportunities for improvement in surface treatment of aluminum alloys, testing non-traditional manufacturing modes, and developing sustainable techniques in FML manufacturing. Opportunities in tooling relate to tool coatings and adjusting machining parameters for optimum finished parts. To enhance sustainability, testing coated drills under cryogenic conditions to reduce lubricant usage is necessary.

Summary: Additive manufacturing is a process that layers materials to obtain 3D parts but lacks necessary surface finishing. To address this, a new technology integrating additive and subtractive processes into a single machine, known as hybrid manufacturing, has been developed. This approach improves manufacturing efficiency and quality by combining additive and subtractive methods.
