In recent years, additive manufacturing (AM) has gained popularity in the aerospace, automobile, and medical industries due to its ability to produce complex profiles with minimal tolerances. Micro-milling is recommended for machining AM-based parts to improve surface quality and form accuracy. Therefore, the machinability of a titanium alloy (Ti6A...

Additive manufacturing, particularly 3D printing, has revolutionized the manufacturing industry by allowing the production of complex and intricate parts at a lower cost and with greater efficiency. However, 3D-printed parts frequently require post-processing or integration with other machining technologies to achieve the desired surface finish, ac...

Ultra-precision diamond turning is widely used in optical manufacturing. However, when only a fixed point at the cutting edge of a diamond tool is used in single point diamond turning, the tool may experience significant wear. Recently, straight-nosed diamond tools have gained popularity in cutting optics due to their ability to improve machined su...

Achieving appropriate cobalt concentration within the matrix when fabricating ultra-thin diamond blades with fused deposition modeling and sintering (FDMS) leads to improved machining performance. This study investigates the effects of cobalt content on mechanical properties such as hardness, relative density, and holding strength of ultra-thin dia...

The growing public concern about sustainable development has increased interest in exploring sustainable machining alternatives. However, the absence of a widely accepted method for evaluating the environmental impact of machining processes and a thorough understanding of the requirements for achieving sustainable development has created a pressing...

Polycrystalline diamond compact (PDC) is composed of a polycrystalline diamond layer with a tungsten carbide substrate, which is commonly used on drill bits. PDC bits are widely used in geological and petroleum drilling. There are frequently issues with failure, such as chipping of teeth during drilling, attributed to the residual stress within the...

Purpose Material extrusion technology is considered to be an effective way to realize the accurate and integrated manufacturing of high-performance metal diamond tools with complex structures. The present work aims to report the G4 binder that can be used to create metal composite filament loading high concentrations of large diamond particles thro...

Existing studies rarely focus on manufacturing complex diamond tools via fused filament fabrication subject to the development of corresponding filaments. This work aims to develop diamond-containing metal composites filament to effectively fabricate ultrathin diamond blade. In this study, properties of filaments with different volumes of diamond a...

As an additive manufacturing technology, Fused Deposition Modeling and Sintering (FDMS) technology can give diamond tools some creative structures to be applied in more fields. To explore the influence of diamond parameters on diamond tools manufactured by FDMS, copper-tin-diamond composite samples with different diamond concentrations and particle...
