Evaluation of the cutting edge fan-shaped during the cutting process by the hydro abrasive water jet

Abstract

This article presents the current state of hydro-erosion cutting and factors affecting the quality of cutting surface. The aim of this article is the evaluation of the fanshaped water spray pattern on the bottom cut edge by the hydro-erosion cutting based on selected parameters like cutting surface roughness and the distance between the inlet and outlet water jet. The results demonstrate that cutting speed had the largest influence on evolution of fan-shaped bottom of the cut edge because increasing cutting speed increases the values of both parameters mentioned above.
