Abstract： The automobile industry is one of the pillar industries of a country， and the huge automobile demand requires a systematic processing and manufacturing industry， and the vehicle panel mould is a key link in the vehicle manufacturing. Through the vehicle panel die， the one-time forming and stamping of the vehicle panel can be completed， and the manufacturing efficiency of the vehicle panel can be improved. The stamping quality of the vehicle panel is closely related to the machining quality of the vehicle panel die. Because of the large size， complex shape and high surface accuracy of the vehicle panel die， the stamping quality of the vehicle panel is closely related to the machining quality of the vehicle panel die. Nowadays， high speed cutting technology is often used to complete the high precision machining of vehicle panel die. High speed machining technology can be used to form good machining accuracy on the surface of vehicle panel die. Based on the analysis of the characteristics of high speed cutting technology， this paper analyzes and introduces its application in vehicle panel die machining.

Keywords： vehicle panel die; high speed cutting technology; application
