The invention relates to the technical field of lifesaving of aviation, in particular to a cumulative cutting method for an escape hatch to solve the problem of difficulty in arrangement of a cumulative cutting rope. The cumulative cutting method for the escape hatch comprises steps as follows: the shape of the pre-cut escape hatch is marked out; a predetermined arrangement line of a cutting rope is divided into multiple first cutting sections and multiple second cutting sections; the cumulative cutting rope is sectioned into multiple first cumulative cutting ropes and multiple second cumulative cutting ropes which correspond to each other, and a cumulative cutting rope protecting jacket is further arranged at each second cumulative cutting rope; the multiple first cumulative cutting ropes and the multiple second cumulative cutting ropes are arranged on the multiple first cutting sections and the multiple second cutting sections respectively for cumulative cutting. By means of the cumulative cutting method for the escape hatch, the cumulative cutting rope can be more conveniently arranged and mounted, the mounting manufacturability of the escape hatch on an airplane is improved, and besides, the condition that the reliability of a product is affected by repeated bending of one cumulative cutting rope is also avoided.
