Abstract: Aiming at the problem of deformation and local stress concentration in the sawtooth radial groove of diamond saw blade under sawing force, the parameters of the radial groove were simulated by using ANSYS Workbench and orthogonal test. The influence of the parameters of the radial groove on the sawtooth deformation, equivalent stress, radial stress and tangential stress was analyzed, and the optimal parameters of the radial groove were obtained. Finally, the experimental results were verified to optimize the parameters of the radial groove.The results indicate that the radius of the bottom hole of the radial groove has the greatest effect on the deformation of the saw blade and the depth has the least effect on the deformation of the saw blade. The width of the radial groove has the greatest effect on the stress of the saw blade and the depth has the least effect on the stress.When the equivalent stress, the maximum tangential stress and the maximum radial stress are optimal, the radius of the bottom hole R is 4 mm, the width of the radial groove B is 3 mm, and the depth of the radial groove H is 17 mm.
