The present study aims to investigate the influence of grinding on shot peened (SP) aluminium alloy 7075 by means of residual stresses. The aluminium alloy was subjected to homogenisation annealing at 475 °C for 2 h, followed by quenching in water to room temperature. After that, the surface was shot peened with different Almen intensities and at different coverages to obtain compressive residual stresses in the surface layer of the material. The grinding operation is then followed to reduce the surface roughness and also to increase corrosion resistance. The first method used for measuring residual stresses was a semi-destructive blind-hole drilling method and the second was a non-destructive X-ray diffraction method. The resulting residual stress profiles reveal that residual stresses throughout the surface layer of all shot peened specimens are of a compressive nature. The highest value of residual stress were obtained after shot peening with 16A and a coverage of 200 %, i.e., –377 MPa at a depth of 250 mm. However, regardless of any shot peening parameters, the compressive residual stresses in the specimens are, after reaching maximal values, directed towards the tensile area with a very similar gradient.
