This invention belongs to the field of machining technology, specifically relating to an optimized design method for stepped drilling tools for weakly rigid laminated structures. This method addresses the problems of workpiece deformation and interlayer scratches that easily occur during drilling of weakly rigid laminated structures. It uses interlayer clearance control as the core indicator and, based on the coupling relationship between drilling axial force and workpiece deformation, constructs a quantitative mapping relationship between the tool's stepped geometric parameters and the interlayer clearance during machining. Furthermore, by establishing a critical clearance criterion for interlayer damage and combining the deformation characteristics under different drilling modes, the key parameters of the stepped tool, namely the step diameter and step length, are optimized. This ensures that the maximum interlayer clearance during drilling remains below the critical value, effectively suppressing interlayer chip intrusion and interface damage, thereby improving drilling quality. This invention realizes a shift in tool design from experience-driven to mechanism-driven, and is applicable to high-quality hole machining of various weakly rigid laminated structures.
