摘要

木质纤维增强氧化镁复合材料（WRMC）作为一种新型建筑装饰装修材料，其以优异的物理力学性能被应用于建筑装饰领域。本文研究了在对WRMC的锥形铣削过程中，铣削参数（锥度角、铣削深度和铣削速度）对切削力和加工后工件表面粗糙度的影响。结果表明：切削力与铣削深度呈正相关，与锥度角、铣削速度呈负相关。表面粗糙度随着铣削深度的增加而增大，随着锥度角和铣削速度的增加而减小。综合分析得到对WRMC的优化切削参数组合：锥度角为75°，铣削速度为45 m/s，铣削深度为0.5 mm，切削力和工件表面粗糙度分别为50.24 N和2.11 μm。

Abstract

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.
