Abstract: A method for machining a drill with tilting blade slot structures for composite machining is provided. In the machining method, a face of the drill produces a downward component force for the inlet material to inhibit the inlet material from turning up; and a cutting edge inclination of an end surface at an outer turning point in a corner region of the drill is a positive value. The face and a flank are firstly partially ground in the corner region of the drill. The face at the outer turning point is ground with a grinding wheel to obtain two tilting blade slot structures. After grinding, a new face and a new cutting edge are obtained; and the cutting edge inclination on the end surface formed by the new cutting edge and a reference plane is a positive angle.
