Hybrid computer numerical control machining center and machining method thereof

A machining method of a hybrid CNC machining center, comprising steps of:

• providing a hybrid CNC machining center including at least a cutting tool head, a laser cladding tool head, and a computer numerical control unit, wherein the cutting tool head and the laser cladding tool head are alternately installed in a tool holder of the hybrid CNC machining center, wherein the laser cladding tool head further includes a temperature sensor and a camera;
• processing a cutting operation, wherein the cutting tool head is configured to cut at least a machined surface of a work-piece;
• and
• processing a cladding operation, wherein the laser cladding tool head is configured to clad the machined surface, and at the same time, firstly detecting a temperature of a molten pool of the machined surface by the temperature sensor, and providing the detected temperature of the molten pool to the computer numerical control unit, wherein if the temperature of the molten pool is under a default temperature, a power of the laser cladding tool head is increased;
• and if the temperature of the molten pool is over the default temperature, the power of the laser cladding tool head is decreased;
• and then detecting a lightness and profile of the molten pool of the machined surface by the camera, and providing the detected lightness and profile of the molten pool to the computer numerical control unit, wherein if the lightness and profile of the molten pool is under a default condition, the power of the laser cladding tool head is increased;
• and if the lightness and profile of the molten pool is over the default condition, the power of the laser cladding tool head is decreased.
