中文摘要:
      目的 揭示微细铣削下的切削深度ap、进给量f、切削速度v对不锈钢310S表面完整性的影响规律,为优化不锈钢310S的切削工艺提供参考。方法 基于响应曲面方法,采用涂层硬质合金微直径铣刀,对不锈钢310S进行了铣削加工试验,对表面粗糙度、表面形貌和显微硬度的数据和信息进行采集并分析,进行多元非线性回归,建立了表面粗糙度Ra与切削参数之间的映射关系,对多元回归方程进行了显著性检验。结果 得到切削参数ap、v、f显著度分别为 0.099、0.620、0.011。基于曲面响应法的试验数据及数学模型,直观地绘制了ap、v、f对表面粗糙度Ra、表面形貌和显微硬度的影响规律图。结论 在一定的切削加工参数范围内,进给量f对微细铣削不锈钢310S表面粗糙度Ra的影响最显著,其次是切削深度ap,切削速度v的影响最小。表面留有摆线状加工痕迹,顺铣侧的残留物分布多于逆铣侧。切削深度ap对310S试件表层显微硬度的影响最显著,其次是切削速度v。减小进给量f是降低不锈钢310S表面粗糙度的有效加工方法。
英文摘要:
      The work aims to provide reference for optimizing cutting process of stainless steel 310S by revealing influence law of cutting depth ap, feed rate f and cutting speed v on surface integrity of stainless steel 310S. Milling experiment was performed to stainless steel 310S using coated carbide micro diameter cutter in response surface methodology (RSM). Then data and information regarding surface roughness, morphology and hardness were collected and analyzed. Multielement nonlinear regression was used, mapping relation between surface roughness Ra and cutting parameters were established, and significance test was performed to multielement regression equation. Significance of cutting parameter ap, v and f was 0.099, 0.620 and 0.011, respectively. Diagram of influence law of cutting depth ap, feed f and cutting speed v on the surface roughness Ra, surface morphology and hardness were plotted visually based on the experimental data and mathematical model of the surface response method. In a certain range of cutting parameters, feed rate f has the most obvious effects on surface roughness Ra of stainless steel 310S, followed by cutting depth ap, and little effects on cutting speed v. Cycloidal processing mark is left on the surface, there is more residue on the milling side than that on the reverse milling side. The cutting depth ap has the most remarkable influence on the hardness of 310S test piece, followed by the cutting speed. Reducing feed rate f is an effective processing method of reducing surface roughness of stainless steel 310S.
