Abstract

In this paper, a simple hole-drilling device was designed to improve hole-depth precision of the drilling. The precision of hole-depth at each step for drilling can be ensured at 0.01mm. Residual deformation around a hole of aluminum casting specimens was obtained by using a phase-shift Moiré interferometry method. Residual strain distribution with different hole-depth was calculated from the residual deformation and analyzed. According to the result of the experiment, the residual strain distribute around the hole is generally compressed under a special hole-depth. The compressed residual strain is reduced with the increase of the distance far away from the center of the hole. In addition, the compressed residual strain declines rapidly with the increase of the hole-depth.
