Advanced Engineering Materials, EarlyView.Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Cutting Temperature Investigation of AISI H13 in High Speed End Milling
International Journal of Engineering Materials and Manufacture, 2016 Heat produced at the tool-chip interface during high speed milling operations have been known as a significant factor that affect to tool life and workpiece geometry or properties. This paper aims to investigate cutting temperature behaviours of AISI H13

Wear behavior of different coated tools in MQL-assisted milling of magnesium-based rare-earth alloys
Journal of Materials Research and Technology, 2023 One of the most important and often employed indicators for describing machinability and machining quality is tool wear. While flank wear is commonly used to gauge the extent of a worn scar, tool wear is characterized more by its shape than its size.

Advanced Engineering Materials, EarlyView.The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Global mining footprint mapped from high-resolution satellite imagery
Communications Earth & Environment, 2023 Mining is of major economic, environmental and societal consequence, yet knowledge and understanding of its global footprint is still limited. Here, we produce a global mining land use dataset via remote sensing analysis of high-resolution, publicly ...

An efficient NC tool path planning approach [PDF]
, 2005 One major problem encountered in NC machining is that cutting load fluctuates in twisty tool paths and increases momentarily when milling concave corners where stock material concentrates.

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 This paper describes a novel tool path generation for three-axis ball-end milling using a local interpolation. After a modified local interpolation using normal unit vectors is introduced, generation of a parametric offset geometry is presented based on ...
