| 摘 要： | 为了提高熔融沉积成型(Fused Deposition Modeling,FDM)成型件的表面质量,提出利用数控加工对FDM成型件进行表面加工的后处理方法,研究打印速度、挤出速度和分层厚度等工艺参数对成型件的成型误差和表面粗糙度的影响,在此基础上,研究数控加工对其加工误差和表面粗糙度的影响。结果表明:FDM成型件表面粗糙度较大,最大达到24.434μm,合理设置打印速度、挤出速度和分层厚度可以有效降低FDM成型件的成型误差;数控加工可以有效降低FDM成型件的表面粗糙度值,表面粗糙度降低到1.979~2.446μm。

| Abstract: | In order to improve the surface quality of fused deposition modeling(FDM)parts,a post-processing method of NC machining for FDM products was presented.The effects of process parameters such as printing speed,extrusion speed and thickness of the layer on the forming error and surface roughness of molded parts were studied.The effects of NC machining on machining error and surface roughness were studied.The results show that the surface roughness of FDM parts is large,the maximum value reaching 24.434μm.The forming error of FDM parts can be effectively reduced by reasonably setting the printing speed,extrusion speed and layered thickness.The surface roughness of FDM parts can be effectively reduced by NC machining,the value reaching 1.979~2.446μm. |
