In general, grinding fluid is supplied from the supplying nozzle to the grinding wheel-workpiece contact zone during the surface grinding process. However, when the profile or curved surfaces need to be machined, the supply of the grinding fluid to the contact zone seems to be more difficult due to the fixed direction of the grinding fluid supplying nozzles. Therefore, the system which can supply the grinding fluid through the grinding wheel was developed and evaluated. In order to evaluate the effectiveness of this system, the maximum workpiece temperature on the backside of the grinding point using the thin wall workpiece was measured by an infrared radiation camera. The flow rate of grinding fluid and grinding parameters showed a significant effect on the temperature and the grinding performance. Moreover, the profile grinding of the turbine blade shape was successfully conducted.
