The invention relates to a laser cutting method for a corner. In the invention, a PLC control program is adopted to control the speed magnification of a CNC numerical control system, so that a machine tool automatically reduces speed magnification and obtains relatively low cutting speed at a contour corner of a cutter path; after smoothly passing through the contour corner of the cutter path, the machine tool gradually raises cutting speed to the normal cutting speed, so that the machine tool can not only reduce cutting speed at the contour corner of the cutter path and smoothly carry out cutting without increasing nitrogen flow for supporting cutting, but also ensure that the machine tool can carry out cutting at normal speed at other sections of the cutter path, thus obtaining relatively high processing efficiency. Moreover, as the control of the processing machine tool is improved, insufficient cutting and rejected slag in the laser cutting process are greatly reduced, thus well protecting a focus lens from being polluted by cutting rejected slag, prolonging the service life of the focus lens and reducing attrition rate thereof.
