The invention relates to a grinding method for a fir-shaped milling cutter, which comprises the following steps of: checking the sharpness and the diameter abrasion loss of the fir-shaped milling cutter, and determining a grinding mode; grinding a front angle, namely grinding the front angle of the fir-tree-shaped milling cutter by adopting a grinding wheel; or grinding the rear angle and the front angle, namely respectively grinding the rear angle and the front angle of the fir-tree-shaped milling cutter by adopting a grinding wheel. The invention further relates to a fir tree type mortise machining method using the fir tree type milling cutter. The fir tree type mortise machining method comprises the steps of milling cutter checking, machining mode determining and one-tool forming machining or two-tool forming machining. According to the grinding method, the regrinding frequency of the fir-tree-shaped milling cutter is increased, the service life of the fir-tree-shaped milling cutter is prolonged by 3-4 tim
