- High-pressure abrasive water jet Cutting Hardox® steel Gray relational analysis
EN This paper presents the results of the Abrasive Water Jet (AWJ) cutting process optimization for Hardox® steel. This type of steel makes it possible to reduce the weight of a work piece and increases the service life of steel elements in comparison with common steel applications. The special combination of features, such as hardness, strength, and toughness, allows using elements with smaller cross-sections. The effect of different pressure levels, traverse speeds and abrasive flow rates, on cutting depth, kerf width and roughness on the cut surface of the Hardox® 500 steel was experimentally tested. In order to determine the most beneficial control parameters of the cutting process, multi-criteria optimization by means of the Gray Relation Analysis (GRA) combined with the Taguchi approach was carried out.
