摘　　要：为了研究激光熔覆增材再制造的Inconel 718合金在干式端铣过程中的可加工性,采用激光熔覆技术在27SiMn合金钢表面涂覆Inconel 718合金。使用正交试验方法进行干式端铣试验,并研究铣削工艺参数对激光熔覆层切削力及表面质量的影响规律。研究结果显示,铣削深度对切削力的影响最为显著,主轴转速、进给速度和铣削深度的增大都会导致切削力的增加。在各个铣削工艺参数中,进给速度对表面粗糙度的影响最为显著,其次是主轴转速,而铣削深度的影响最小。当主轴转速为2 000 r/min、进给速度为150 mm/min和铣削深度为0.5 mm时,表面粗糙度值最低。此外,铣削深度对表面显微硬度的影响最为显著。这些发现对激光熔覆涂层机械加工过程中的工艺参数选择具有指导和参考意义。To investigate the machinability of Inconel 718 alloy in dry end milling during laser cladding additive manufacturing, the laser cladding technique was used to coat Inconel 718 alloy on the surface of 27SiMn alloy steel. Orthogonal experimental design was employed to conduct dry end milling experiments and study the influence of milling process parameters on cutting forces and surface quality of the laser cladding layer. The research results indicate that milling depth has the most significant effect on cutting forces, and an increase in spindle speed, feed rate, and milling depth all lead to an increase in cutting forces. Among the milling process parameters, the feed rate has the most significant impact on surface roughness, followed by spindle speed, while the effect of milling depth is the smallest.The minimum surface roughness value was achieved when the spindle speed was set at 2 000 r/min, the feed rate was set at 150 mm/min, and the milling depth was set at 0.5 mm. Additionally, milling depth has the most significant influence on surface microhardness.These findings provide guidance and reference for process parameter selection in the mechanical machining process of laser cladded coatings.
