Evaluation of Cut Quality on AlMg4.5Mn Material Using AWJ Containing Recycled Abrasives

Recycling the abrasives used in Abrasive Water Jet cutting is a theme that touches multiple areas. First of all, it is the economic aspect (increasing the price of abrasives on world markets, its availability and ensuring timely supplies, as well as the environmental aspect of abrasives extraction and transport). For used abrasive material recycling the sorting lines are used, which consist of sorting and drying equipment. However, recycled material should achieve sufficient cutting efficiency when reused. To determine whether it achieves recycled abrasive material is sufficiently effective, an experiment was performed. The assessment was evaluated through selected roughness parameters Ra, Rq, Rz and Rt and Abbott-Firestone material fraction curve for AlMg4.5Mn aluminum alloy samples (EN AW 5083). The results of the experiment can contribute to the widespread use of recycled abrasive material.
