| 目的 探究离心研磨自动化加工工艺对钛合金表面粗糙度的影响。 方法 选取了影响离心研磨加工效果的主要工艺参数（磨料材质、磨料粒径、滚筒转速），并使用单因素试验法对 TC21 钛合金进行了离心研磨加工试验。以表面粗糙度为评价指标对工艺参数进行了分析和优化。采用优化后的工艺参数对 TC21 钛合金进行了表面离心研磨加工，在此基础上研究了表面二次细化加工对 TC21 钛合金表面粗糙度的影响，并对比了加工前后工件的表面粗糙度值和表面形貌。 结果 确定了较优的离心研磨 TC21钛合金的工艺参数，即：磨料材质选用氧化铝，磨料粒径为 5 mm，滚筒转速为 240 r/min。采用优化后的工艺参数进行了离心研磨加工试验， TC21 钛合金表面粗糙度值由 1.412 μm 低至 0.513 μm；表面二次细化加工后，工件表面粗糙度值由 0.513 μm 降至 0.267 μm，加工纹理和缺陷消失。 结论 采用优化后的工艺参数对 TC21 钛合金取得了较好的离心研磨加工效果，结合表面二次细化加工，使 TC21 钛合金表面粗糙度值降低两级，并修复了表面缺陷，验证了使用离心研磨工艺加工 TC21 钛合金的可行性。 |

| Objective To explore the influence of centrifugal grinding automation processing technology on surface roughness of titanium alloy. Methods Single factor experiments were conducted using the main process parameters affecting grinding results. The process parameters were analyzed and optimized by selecting surface roughness as the evaluation index. Using the optimized process parameters, this paper conducted the experiment of surface grinding on TC21 titanium alloy. On this basis, the influence of surface secondary refining process on surface roughness of TC21 titanium alloy was studied, and the surface roughness and surface topography of the workpiece before and after processing were compared. Results The experiments determined the optimal parameters of centrifugal grinding TC21 titanium alloy: alumina as abrasive material, abrasive particle size of 5 mm, and drum rotation speed of 240 r/min. After processing with the optimized parameters, the surface roughness of the workpiece decreased from 1.412 μm to 0.513 μm; after surface secondary refining processing, the surface roughness of the workpiece decreased from 0.513 μm to 0.267 μm. Besides, the texture and defects disappeared. Conclusion Good experimental results were obtained under the optimized processing conditions. In combination with the surface secondary refining processing, the surface roughness of TC21 titanium alloy fell by two levels, and surface defects were fixed. The experimental results verified the feasibility of centrifugal grinding processing on TC21 titanium alloy. |
