Automatic machining system and method for bearing seat

The invention provides an automatic machining system and method for a bearing pedestal, the system comprises at least two subsystems, and each subsystem comprises an interaction device, a control device and a machining device which are connected in sequence. Main working data and sub-working data which are stored in the interaction device and are read and called by the control device are set, the main working data are common parameter data of different bearing seats, relevant parameters can be modified through the interaction device, the sub-working data are specific machining parameter data, sub-working data instructions are set in the main working data, and the main working data and the sub-working data instructions are matched. The sub-working data can be searched and called through the main working data, related data can be conveniently inquired and maintained, the working efficiency can be improved, only fixed data and to-be-modified parameter data need to be compiled during working data compiling, speci
