Digital twin-driven green material optimal selection and evolution in product iterative designSpringer Science and Business Media LLC - Tập 11 - Trang 647-662 - 2023
Feng Xiang, Ya-Dong Zhou, Zhi Zhang, Xiao-Fu Zou, Fei Tao, Ying Zuo
In recent years, green concepts have been integrated into the product iterative design in the manufacturing field to address global competition and sustainability issues. However, previous efforts for green material optimal selection disregarded the interaction and fusion among physical entities, virtual models, and users, resulting in distortions and inaccuracies among user, physical entity, and ...... hiện toàn bộ

The integration of nanomaterials such as carbon nanotubes (CNTs) into microsystems is highly desirable, in order to make use of the unique nanomaterial properties in real devices. However, the CNT-to-microsystem integration is challenging to implement in a manufacturable, cost-effective industrial process. This paper presents our work towards a process for making complete, integrated CMOS / MEMS s...... hiện toàn bộ
Surface integrity of ball burnished bioresorbable magnesium alloySpringer Science and Business Media LLC - Tập 11 - Trang 342-362 - 2022
G. V. Jagadeesh, Srinivasu Gangi Setti
Magnesium alloys are potential biodegradable and biocompatible implant materials because of their excellent biological properties. Recently, interest in these alloys as a promising alternative for temporary orthopedic implants has grown owing to their desirable biological, mechanical, and physical properties. However, the application of magnesium alloys is hindered by their rapid degradation and l...... hiện toàn bộ
Optimum calibration of a parallel kinematic manipulator using digital indicatorsSpringer Science and Business Media LLC - Tập 2 - Trang 222-230 - 2014
V. B. Saputra, S. K. Ong, A. Y. C. Nee
This paper presents a calibration method for parallel manipulators using a measurement system specially installed on an external fixed frame. The external fixed frame is important as an error reference for calibration in certain operations, such as in the configuration of a parallel manipulator functioning as a machine tool where the workpiece is fixed to a worktable. The pose of the end-effector ...... hiện toàn bộ
Improved time-optimal B-spline feedrate scheduling for NURBS tool paths in CNC machiningSpringer Science and Business Media LLC - Tập 11 - Trang 111-129 - 2022
Yang Li, Fu-Sheng Liang, Lei Lu, Cheng Fan
Feedrate scheduling in computer numerical control (CNC) machining is of great importance to fully develop the capabilities of machine tools while maintaining the motion stability of each actuator. Smooth and time-optimal feedrate scheduling plays a critical role in improving the machining efficiency and precision of complex surfaces considering the irregular curvature characteristics of tool paths...... hiện toàn bộ
