The invention discloses a multifunctional laser digital-control processing system with a central control system, characterized in that the central control system is provided with a processor, a process flow database, a data-loading platform and a processing control platform. The parameter input end of the processor is connected with a processing parameter input device for acquiring processing parameters and extracting processing process flows, the processing parameters are implanted in the processing process flows for generating a processing program, and a three-dimensional output end group of the processing control platform is connected with a laser head three-dimensional travel system. The invention has the advantages that a plurality of laser processing processes can be realized, and a working piece can be processed in a plurality of different positions at different angles. By adopting the automatic control technology, the gas mixing proportion and the gas pressure of a single gas source or a plurality gas sources are controlled, and the travel path of a relative laser head, and the supply proportion and the gas pressure of auxiliary gases are set so that the requirement of integrating a plurality of laser-processing systems are satisfied.
