Hydroabrasive disintegration of rotating Monel K-500 workpiece

Abstract

This paper addresses the hydroabrasive disintegration of the difficult-to-machine material, Monel K-500. An experiment was performed using a hydroabrasive cutting system with an additional rotating module. The objective of the preliminary experiments was to identify significant technological factors and investigate their impact on the machined surface quality of difficult-to-machine materials. To describe the impact of parameters, experiments were carried out according to the design of experiment. Surface roughness parameters were measured, and surface topography visualisation and analysis were conducted. The results concluded that the abrasive mass flow rate and traverse speed significantly influence the surface roughness and material removal rate. From a practical point of view, the technology can prepare semi-finished workpiece shapes; however, surface finishing is necessary.
