Full-automatic laser cutting and groove machining system and method

A full-automatic laser cutting and groove machining system comprises an automatic feeding module, a laser cutting module and a groove machining module. Wherein the automatic feeding module is used for feeding a steel pipe to be subjected to laser cutting into the laser cutting module and sending feeding completion information to the laser cutting module; the laser cutting module is used for receiving the feeding completion information sent by the automatic feeding module, automatically generating a laser cutting instruction, carrying out cutting and chamfering operation according to preset parameters, and sending laser cutting completion information to the groove processing module after the laser cutting module completes the cutting and chamfering operation; and the groove processing module is used for receiving the laser cutting completion information sent by the laser cutting module, automatically generating a groove processing instruction, matching a proper knurling wheel and a pressing wheel according to
