In previous paper, cleaning and removal functions of a waterjet were examined and the effect was validated as a means of inprocess dressing. This paper discribes : a) the optimal injection pressure of a waterjet dresser depending on the grain size of the wheel and b) the dressing effect of a waterjet dresser in relation to its injection angle in grinding Ti6Al4V using a cBN wheel. The optimal injection pressure of a dresser differed depending on the grain size of the wheel, and the condition of a processed surface deteriorated when the injection pressures were not optimized in the in-process dressing with waterjet. It was clarified that higher waterjet pressure was required to remove chips as the grain size of a wheel became smaller in the dressing using wheels of a grain size from #230 to #1000. The collision speed of a waterjet with a wheel differed depending on the injection angle. When a waterjet collided with a wheel in a direction opposite to its rotation, the collision speed became higher and a better dressing result was obtained. Conversely, when a waterjet collided with a wheel in the same direction as its rotation, the dressing effect decreased. It became clear that the injection angle of a waterjet has considerable influence on the dressing effect.}, pages = {1315--1319}, title = {ウォータージェットを用いた砥石のインプロセスドレッシング (第2報): 噴射圧力・噴射角度がドレッシング特性に与える影響}, volume = {71}, year = {2005} }
