The invention discloses a combustion chamber shell machining benchmark design method. The method comprises the following steps: firstly, placing a combustion chamber shell with an external hanging piece arranged on an outer surface and a laser three-dimensional scanner on a platform; 2, measuring the combustion chamber shell by using a laser three-dimensional scanner to generate a three-dimensional point cloud model; fitting the three-dimensional point cloud model with a preset three-dimensional design model of the combustion chamber shell; 3, taking the central vertical line of the three-dimensional design model as I-I reference, and taking the central horizontal line of the three-dimensional design model as II-II reference; and rotating the three-dimensional point cloud model around the central axis, and when the external hanging piece models of the three-dimensional design model are all located in the size range of the external hanging piece models of the three-dimensional point cloud model, determining a
