The present invention provides a double-point incremental forming manufacturing method and apparatus based on deep reinforcement learning. The method comprises: obtaining a three-dimensional model to be manufactured, performing layering to obtain a plurality of main working paths and a plurality of candidate supporting paths, and selecting an initial current main working path and a current supporting path; respectively cyclically controlling, according to the current main working path and the selected current supporting path, mechanical arms of a master robot and a slave robot for incremental forming in an actual application environment, to obtain a formed curved surface; and taking a deviation value of the formed curved surface and a target curved surface as a state vector, applying a pre-trained deep reinforcement learning model for reinforcement learning, cyclically outputting a supporting path corresponding to the next main working path, and cyclically updating the current main working path and the curren
