Abstract :

Cold cutting properties is one of the advantages of abrasive water jet usage that does not generate heat and prevent melting or cracking or warping and surface hardening of the parts. In this study, the effect of nozzle diameter and water pressure in two different amounts has considered on CK45 steel cutting surface roughness. The results show that by increasing the nozzle diameter of 0.76mm to 1.1mm, cutting surface roughness. Also by increasing water pressure from 2500 bar to 3000 bar, although there is no significant change in surface quality, but cutting surface roughness has decreased by increasing water pressure and cutting quality increases.
