The invention discloses a method for etching a non-developable FSS curved surface by a multi-axis precision laser processing machine tool. The method comprises the following steps that drawing and programming are conducted, any bus of an FSS curved surface workpiece is segmented, a central point of each section of bus is solved, a plane standard FSS graph is projected onto the FSS curved surface according to the positions of the central points, and a processing program is written according to the projected graph; the workpiece is clamped and aligned, and the FSS curved surface workpiece is connected to the laser processing machine tool through a tool; the coordinate origin of the X/Y/Z axis of the workpiece is calibrated as the machining coordinate origin; processing parameters are imported, and the processing program is imported into a control system of the laser processing machine tool; a plane standard FSS graph is imported, and the plane standard FSS graph is imported into the control system of the laser
