Double-inclined hole and machining method thereof

The invention discloses a double inclined hole and a machining method thereof, and relates to the technical field of inclined hole machining, and the machining method of the double inclined hole comprises the steps that workpiece size information, machining information and machining tool size information are obtained, and a corresponding workpiece three-dimensional model and a corresponding machining tool three-dimensional model are constructed; the machining information comprises size information of theoretical double inclined holes to be machined; rotating parameters of the workpiece three-dimensional model and the machining tool three-dimensional model are selected, simulation machining is conducted to form virtual double inclined holes, and when the difference index of the virtual double inclined holes and the theoretical double inclined holes is larger than or equal to a preset threshold value, the rotating parameters are optimized till the difference index is smaller than the preset threshold value; and
