Special Issue Information

Dear Colleagues,

Ultra-precision manufacturing provides essential means for manufacturing products with regard to the demand for the continuous improvement of product quality and performance in aerospace, biomedicine, advanced optics, photonics, telecommunication, etc. The development of ultra-precision manufacturing methods, machine tools, and measurement instruments is extremely crucial. It is especially useful in achieving high-precision and high-efficiency manufacturing with new structures and materials. On specific product surfaces, it needs to achieve nanoscale and structural manufacturing.

Accordingly, this Special Issue seeks to showcase regular research papers, reviews, and communications that focus on the frontiers of ultra-precision manufacturing. It will serve as a platform for the communication of the latest developments and innovations in machining mechanisms, machine tools, measurement instruments, and ultra-precision assembling.

In order to understand the formability of as-received tempered commercial pure titanium grade 2 foils (CP Ti Gr2) with a thickness of 38 µm, a series of micro limited dome height (µ-LDH) tests were conducted in quasi-static speed (0.01 mm/s) at room temperature without the use of a lubricant. A technique developed at NIU was also used to create micro-circular grids (ϕ50 μm) on the as-received material. The forming limit curve (FLC) of the CP Ti Gr2 foils was obtained through the proposed µ-LDH test. For having mechanical properties of the CP Ti Gr2 foils for LS-Dyna FEA (Finite Element Analysis) simulations, a series of tensile tests in three directions were also conducted at room temperature with the same speed. The obtained FLC has been validated using a micro deep drawing case study in which both FEA simulations and experiments were conducted and compared. It has been proven in this study that the FLC obtained using the proposed µ-LDH test can be used for an extremely thin sheet-metal-forming process by the automotive, aerospace, medical, energy, and electronic industries, etc., right away for product design, forming process development, tool and die designs, and simulations, etc. Full article
