A new experimental method of in-process dressing has been conducted by means of water-jet, as well its application investigated in the present study. While the workpiece is difficult to be ground by the surface grinding machine, the high pressure watenjet is supplied to the grinding wheel as a supplementary method. The principle of this method can be simply described as that the waterjet is a kind of processing technique, which is able to strip the chips on the surface of the grinding wheel without damaging it by adjusting the injection pressure and stand-off distance. The dressing effects are examined according to the surface conditions of the grinding wheel and ground workpiece by a surface roughness and profile measuring device and a microscope. Because of the complexity of the interaction influences between the jet pump pressure and the stand-off distance on the dressing results, in this report at fixed stand-off distance condition the effects of the jet pressure on the grinding wheel of CBN #325 and finished surface of Ti6A14V materials have been clarified. From the results of the experiments, it was found that the dressing life time of the grinding wheel and the roughess of the ground material finished surface have been improved distinctly when the injection pressure is 107.1MPa at stand-off distance 20mm. On the other hand much lower pressure will have no influence on dressing results, and much higher one will damage the CBN wheel.
