description The invention provides an automatic evaluation method and system for a non-closed blade profile of a precision forging blade, and the method comprises the steps: extracting theoretical closed blade profile data with a normal vector from a three-dimensional model, and obtaining the actual measurement data of the blade profile; constructing an automatic evaluation network of the non-closed blade profile of the precision forging blade, wherein the automatic evaluation network comprises a blade profile segmentation module, a K point detection module, a blade profile thickness detection module, a blade profile contour detection module and a blade profile out-of-tolerance detection module; and inputting the actually measured data and the theoretical closed blade profile data of the to-be-evaluated precisely-forged blade profile into the precisely-forged blade non-closed blade profile automatic evaluation network to obtain a K-point detection report, a blade profile contour detection report, a blade profile thicknes
