The wood fiber reinforced magnesium oxide composite (WRMC) material, as a new decorative building product, has been used in the construction and decorating field due to its excellent physical and mechanical properties. The cutting force and the surface roughness of the workpiece during taper milling of WRMC were studied. The results showed that the cutting force was positively correlated with the milling depth, but negatively correlated with the taper angle and the milling speed. The surface roughness increased with the increase of the milling depth and decreased with the increase of taper angles and milling speeds. An optimized cutting parameter combination with the taper angle of 75°, the milling speed of 45 m/s, and the milling depth of 0.5 mm was proposed. Under the above conditions, the cutting force and the surface roughness were 50.24 N and 2.11 μm, respectively.
