This paper proposes an optimal button arrangement of a percussion drill bit and its operating condition to improve drilling efficiency. A new evaluation method is introduced for the that utilizes superimposed impact area, blank deviation moment as quantitative indices evaluate buttons on rock surface. To determine conditions, progressive metamodel-based design optimization was conducted using analysis response, then solution determined through iteration. Consequently, all were reduced...
In addition to the textile industry, unwinding of cable or fiber is used in various fields such as electronics, communication, and guided weapons. The released from package exhibit a complicated behavior, entailing combination rotational translational motion. This causes problems entangling fracture. Therefore, it necessary study boundary adhesion conditions prevent failure. this study, an experimental device for analysis was developed, behavior analyzed experimentally under conditions....
Recent advances in additive manufacturing have provided more freedom the design of metal parts; hence, prototyping fluid machines featuring extremely complex geometries has been investigated extensively. The fabrication via requires significant attention to part stability; however, studies that predict regions with a high risk collapse are few. Therefore, novel algorithm can detect precisely is proposed herein. reflects support span over faceted surface propagation and invalidates...
Waterjet is a device that cuts or crushes materials using water pressure injected through the nozzle. Especially, Low waterjet used in stripping and cleaning work. The patterns of low determined by various design variables, such as number nozzles, an angle gear ratio so on. In order to optimize pattern, optimum required depending on shape target structure. To do this, large analysis models should be used. This study reduced time automating creation desired model with simple changes conducted...
In metal product manufacturing, additive manufacturing (AM) is a method that has the advantage of fabricating complex shapes and customized production, unlike existing machining methods. However, owing to characteristics AM process, anisotropy macrostructure occurs because various causes such as scan direction, melting, fusion, cooling powdered material. The realized from when single layer stacked in one it expressed orthogonal anisotropy. Here, classical lamination theory applied simply...
