High Performance Grinding Springer for Research

High performance grinding (HPG) also called high efficiency deep grinding (HEDG) is characterized by extremely high specific material removal rates (MRR), using high wheel speed, high depth of cut, and high feed rate with superabrasive tools resulting generally in very low specific energy (6–15 J/mm 3 for ferrous material) compared to other grinding processes (Table 1).

Principles of Modern Grinding Technology ScienceDirect

Examples of high-speed grinding are described including crankshaft grinding and drill-flute grinding. Benefits include not only greatly increased removal rates but also reduced energy requirements to remove a volume of material. The development of these trends is described with references to key publications and underlying principles.

Laser assisted micro grinding of high strength materials

This paper aims to develop a laser assisted grinding process capable of manufacturing micro features in high strength materials. A diode laser with wavelength 808 nm was set on a precision grinding machine. Micro grooves were fabricated on high strength materials including silicon nitride and aluminium oxide by using the laser assisted grinding process, i.e. laser pre-heat workpiece flowed by

12/08/2012· High efficiency deep grinding (HEDG) achieves very high removal rates with moderate temperature rise. It is shown that key factors are high wheel speeds, large depths of cut and moderately high work speeds. High removal rates in HEDG are associated with very efficient grinding and very low specific energy compared to conventional grinding. Although HEDG-enabled machine tools are
