Cylindrical Grinding Using Step Drill and Its Technological Improvement;

Study of Virtual Simulation of Grinding of Digital Gear Tooth Surface;

Effect of Grinding on Square Degree of Demagnetization Curve of Cylinder Nd-Fe-B Permanent Magnet Alloy;

Progress on the Modeling of Grinding Process;

With the continuous application of ultra-hard high speed steel and other materials hard to be machined in tool industry,higher requirements have been put foward to the grinding process for tools.

Grinding is a complicated process, to avoid researching the complicate d grinding hardening process in mechanism, we investigated grinding process usin g BP arithmetic and developed a simulation software using improved BP arithmetic .
