アブレシブジェット加工面に生じるしま状粗さに関する実験的解析

抄録

Experimental investigation is carried out in order to determine the effect of the cutting parameters such as abrasive feed rate, nozzle discharge pressure, nozzle traversing speed, nozzle size and material of the specimen on the striated roughness of the surface in abrasive waterjet cutting. It is shown that when the combination of nozzle traversing speed and nozzle discharge pressure is chosen so that the maximum kerf depth is kept constant, a smooth surface can be obtained by the combination of slow nozzle moving speed and low discharge pressure. It is also shown that the wavelength of striation ranges mainly from l to 1.5 mm, regardless of the cutting parameters.
