An experimental investigation of air boundary layer flow in grinding using the laser doppler anemometry technique

This invited paper described work completed as part of the project: EPSRC-Industry [GR/S82350]. New insight and improved knowledge of the boundary layer flows around the periphery of a grinding wheel were obtained. This was the first use of Laser Doppler Anemometry in grinding under industrial conditions and allowed, for the first time, theoretical mapping of 3-Dimensional velocity profiles to be validated with experimental measurements. The work also led to the development of a novel positioning system for nozzles designed to minimise flow impedance and improve fluid penetration to the contact region which was validated in cooperation with industrial partners.
