TL;DR: In this article, the authors proposed a numerically efficient NURBS interpolation scheme which consists of two stages namely preprocessing and interpolating, where the parameter interval is split into several blocks at breakpoints and an iterative numerical quadrature method is applied for each block.

TL;DR: The present study mainly provides a numerical framework than a method that can be theoretically used by different numerical methods for solving Ordinary Differential Equation (ODE), such as Euler’s method, Runge–Kutta method, Adam's multistep methods, etc., in this framework for derivation of iteration formula with corresponding construction of coefficient matrix of iterations formula.

TL;DR: In this article, a new analytical method, to identify crucial geometric errors for a multi-axis machine tool is proposed based on multibody system (MBS) theory and global sensitivity analysis.

TL;DR: In this paper, a 3-factor, 5-level welding experiment is conducted by Taguchi L25 orthogonal array through the statistical design method, and the output results are efficient connection length of left side and right side, top width (WT) and bottom width (WB) of the weld bead.

TL;DR: In this article, a comparative study of magnetic field assisted electrical discharge machining and conventional electrical discharge was conducted to analyze the discharge energy flowing and temperature distribution of workpiece, electrode tool and debris, and the effects of external magnetic field on the machining performance, environmental impacts and energy efficiency.
