This paper deals with the abrasive waterjet turning of newly developed hybrid MMC A359/B4C/Al2O3 produced by electromagnetic stir casting. The justification of the fabrication was revealed by microstructural images and x-ray diffraction results. The main aim of the study is to analyse the machining behaviour of produced hybrid MMC under abrasive waterjet turning. The surfaces created at different traverse speed were discussed in terms of surface integrity and surface texture. Optical profilometer was used to generate surface roughness report and 3D visualization of the machined surface. Olympus LEXT OLS 3100 laser confocal microscope was used to collect 2D and 3D surface topographical details of the machined surface. Surface morphology was discussed by FE-SEM images to evaluate surface defects. Residual stresses and microhardness test through the depth profile were also carried out to analyse the machined surface and subsurface. It has been found a perfectly round, slightly undulated surface which shows ploughing nature. The results also reveal the higher rate of material removal with rough cutting. © 2017 The Society of Manufacturing Engineers
