Today, there are many different methods for cutting hard and difficult to machine materials such
as stone, composites, ceramics, metals and alloys. In most of these methods, it is very difficult to achieve
the desired surface quality and tolerance range. The abrasive water jet can cut smoothly and within the
desired tolerance range with water and abrasive grit without any chemical material. In this study, AL7075
T651 aluminum alloy material was cut on an abrasive water jet machine by changing the cutting pressure,
abrasive flow rate and feed rate values at 3 different levels and keeping the other parameters constant, and
the surface roughness and deviation of the holes from the circularity values were examined after cutting.
According to the data obtained after the experiments, the increase in cutting pressure and abrasive flow rate
decreased the surface roughness, while the feed rate increased. Increasing the cutting pressure decreased
the deviation from circularity, while the feed rate and abrasive flow rate increased the deviation from
circularity.
