In this study, the effect of nozzle traverse speed on the geometric tolerances in the drilling of AA 7075 aluminum alloy by abrasive water jet was investigated. Holes were drilled with a diameter of 10 mm using 10 different nozzle traverse speeds (10, 16, 24, 34, 45, 55, 65, 75, 90 and 110 mm/min) and the other parameters were kept constant. Circularity and cylindricity deviation of the holes drilled using different nozzle traverse speeds was measured using a CMM. It was found that the increase in nozzle traverse speed results in increased deviation values from circularity and cylindricity. As a result, increased nozzle traverse speed reduces the amount of abrasive contacting the unit surface and the cutting process does not occur in accordance with the desired geometry.
