Hard materials have found extensive applications in the fields of electronics, optics, and semiconductors. Parallel grinding is a common method for fabricating high-quality surfaces on hard with high efficiency. However, surface generation mechanism has not been fully understood, resulting lack an optimization approach parallel grinding. In this study, profile formation processes were analyzed under different conditions. Then, novel was proposed to improve finish grinding, experiments...
This paper presents the nonlinear analysis of stability and dynamic rotational accuracy an unbalanced rotor supported by aerostatic journal bearings. A finite element method is utilized with Runge-Kutta fourth order to solve transient Reynolds equation dynamics equations simultaneously for response rotor. The behavior center analyzed under different masses. It shown that responses strongly depend on mass. periodic, multi-periodic or quasi-periodic motions are observed as mass changes. Under...
Polymethyl methacrylate (PMMA) is a material with good surface wettability and has unique widespread applications in industrial fields. However, fabricating this an environmentally friendly way while maintaining its mechanical robustness remains challenging task. One effective through the rational design of microstructure surfaces. The current study fabricated pyramid array on mold using offset-tool-servo flycutting, which was then combined hot embossing to replicate inverted PMMA surface....
This study develops a comprehensive numerical model employing computational fluid dynamics for the precise prediction of nitrogen oxide (NO) formation and reduction in industrial-scale calciners. Through integration Euler–Lagrange multiphase particle cell methods with global chemical kinetic reaction model, it explores complex NO migration mitigation strategies. The research validates against empirical data from cement plant, revealing limited impact traditional staged combustion due to...
In ultra-precision cutting, the inherent working frequency and positioning accuracy of actuators are decisive. It is challenging to generate multi-scale cutting motions with high on a hierarchical scale simultaneously. this study, novel micro nano device multiple axes micro-scale in millimetres nanoscale micron meters developed for overcoming challenge. The structure designed small form factor dimension comparison other auxiliary devices machine tools. magnetic field simulation also used...
In this study, in order to improve and restore the performance of polishing pads reduce cost chemical mechanical polishing, three types material pads, namely, polyurethane, damping cloth, non-woven fabric, were selected for experiment. Accordingly, each pad was set up with diamond conditioner high-pressure micro-jet (HPMJ) conditioning control experiments. Subsequently, fluctuation ranges removal rate on 2.73-3.75 μm/h, 1.38-1.99 2.36-4.32 respectively under HPMJ method, while 1.80-4.14...
