The invention discloses an engine interface digital measurement method, which comprises the following steps of: 1, establishing a coordinate system: a, establishing an original point and an X axis, b,establishing an origin of a coordinate system, c, establishing a Y axis, and d, establishing a Z axis to form a three-dimensional coordinate system of the engine 1, and 2, conducting digital measurement on the interface 7 of the engine 1: a, scanning the interface 7 of the engine 1, scanning the round surface data of the interface 7, and scanning the cylindrical shaft data of the interface 7, b,positioning the interface 7 of the engine 1, positioning the position of the interface 7 through an outer round surface 8 and an axis 9 of the interface 7, and determining the direction of the interface 7 through axis 9 data, and c, performing data application on the interface 7 of the engine 1, and completing establishment of a coordinate system of the engine 1 and measurement of the interface 7.The coordinate system esta
