Abstract
This paper investigates the evolution of residual stresses induced during a three steps hole making sequence (drilling => boring => reaming) that enables to manufacture accurate holes. The objective is to characterize how the 1st and 2nd operations may affect the final surface integrity. Surface residual stresses induced by each step are analysed by X-ray diffraction. It has been revealed that the first roughing operation (drilling) determines the thickness of the final affected layer, whereas the residual stress state in the external layer is controlled by the last operation (reaming). Reaming induces a compressive layer in the external layer. Finally it has been shown that boring does not contribute significantly to the final residual stress state.
