Parallel Efficiency and Parametric Optimization in CASTEP
Parallel Architectures, Algorithms and Programming, International Symposium on
By Jun Chen,Liangjie Fu,Huaming Yang
Issue Date:December 2011
Parallel efficiency is always a fundamental research field in high performance computing. This paper focuses on parallel computing at high performance computing cluster with CASTEP program, discusses multi-core parallel efficiency in CASTEP, and analyses t...
A Computer Numerical Controlled System with NURBS Interpolator
Computer Science and Information Engineering, World Congress on
By Chen Liangji
Issue Date:April 2009
Using the advantage of Non-Uniform Rational B-Spline(NURBS) curves to represent spatial curves, an instruction format with NURBS curves, which is suitability for 3-axis coordinated real-time interpolation, is presented against the current line and arc inte...
Kinematics Modeling and Post-Processing Method of Five-Axis CNC Machine
Education Technology and Computer Science, International Workshop on
By Chen Liangji
Issue Date:March 2009
Five-axis complex surface machining on a Computer Numerically Controlled (CNC) machine needs CAD/CAM system for the cutter location and orientation data. Since these data are defined with respect to the coordinate system of work-piece, they need to be conv...
