A numerical control metal cutting method is characterized in that: when an operator needs to use the numerical control metal cutting machine, firstly, the operator rotates the first handle 307, drives the first rotating shaft 306 to rotate through the first handle 307, drives the second bevel gear 305 to rotate through the first rotating shaft 306, drives the first bevel gear 304 to rotate through the second bevel gear 305, drives the threaded rod 301 to rotate through the first bevel gear 304, so that the threaded rod 301 drives the first horizontal plate 302 to move, thus achieving the purpose of adjusting the height of a workpiece, rotates the second handle 406, drives the disc 403 to rotate through the second handle 406, drives the first vertical rod 404 to move through the disc 403, drives the arc-shaped block 502 to move through the first vertical rod 404, when the arc-shaped block 502 and the plate 504 are mutually attached, screws the bolt 505, fixes the plate 504 through the bolt 505, switches on an external power supply of the electric push rod 603, and starts the electric push rod 603, the second vertical rod 602 is driven to a proper position by the electric push rod 603, the motor 604 is started, the cutting blade is driven to rotate by the output shaft of the motor 604, so that the purpose of fixedly cutting a workpiece is achieved, when waste chips are generated on the workpiece, the external power supply of the blower 702 is switched on, the blower 702 is started, air in the blower 702 blows the waste chips through the air pipe 703, and the purpose of preventing the waste chips from splashing is achieved.
