The invention relates to a motor vehicle aluminum alloy wheel with a Udercut weight reduction structure on the inner side of a rim and a machining strengthening method of the motor vehicle aluminum alloy wheel. Compared with a traditional spoke weight reduction structure, the Udercut weight reduction structure has the advantages that the machining process is more advanced, and the light weight is more remarkable. In addition, tests prove that the fatigue life of the wheel with the Udercut weight reduction structure is better than that of a wheel with a spoke weight reduction structure. According to the machining method, a special groove cutter is added, and special machining process parameters are adopted, so that the Udercut weight reduction structure is obtained. The spinning machining method is added, the roller spinning technology is adopted, the strength and hardness of the Udercut weight reduction structure are improved, and perfect balance between weight reduction and mechanical strength is achieved. Compared with a traditional spoke weight reduction structure, the Udercut weight reduction structure has the advantages that the machining process is more advanced, and the light weight is more remarkable. In addition, tests prove that the fatigue life of the wheel with the Udercut weight reduction structure is better than that of a wheel with a spoke weight reduction structure.
