Machining method and device, workpiece and computer storage medium

The invention relates to the technical field of workpiece machining, aims to solve the technical problem of low machining efficiency of some known workpieces, and provides a machining method, equipment, a workpiece and a computer storage medium. The processing method comprises the following steps: placing a first part and enabling a first large surface to face upwards; a groove located on the first large face and a boss allowance located on the second large face are formed from the first large face to the second large face in a semi-shearing stamping mode, and the groove bottom face of the groove is located between the first large face and the second large face; stamping from the first large surface to the second large surface, and forming a first step at the outer edge of the first part; the first part is placed, the second large face faces upwards, and the workpiece is clamped; and carrying out fly-surface milling on the boss allowance from the second large surface, and stamping the second large surface on
