摘　　要：为了获得给定范围内的砂带磨削钛合金表面粗糙度工艺参数的最优区间,以钛合金TC4为研究对象,进行砂带磨削表面粗糙度试验。构建砂带磨削钛合金表面粗糙度的经验公式,分析表面粗糙度对工艺参数的灵敏度,获得工艺参数的稳定域与非稳定域。结合正交试验中的极差分析,得到工艺参数对表面粗糙度的影响曲线,进行了工艺参数的区间优选。研究结果表明:表面粗糙度对磨料粒度的变化最为敏感,对砂带线速度的变化最不敏感;磨料粒度的优选范围为120#~150#,砂带线速度的优选范围为15~20 m/s,磨削压力的优选范围为10~15 N。本研究对砂带磨削钛合金表面粗糙度控制提供了理论方法与试验依据。In order to obtain the optimal range of process parameters for abrasive belt grinding of titanium alloy surface roughness within a given range,titanium alloy TC4 was used as the research object to conduct abrasive belt grinding surface roughness tests.The empirical formula of grinding titanium alloy surface roughness was established,analyzed the sensitivity of the surface roughness to the process parameters,and obtained the stable and non-stable regions of the process parameters.Based on the range analysis of the orthogonal experiment,the influence curve of the process parameters on the surface roughness was obtained,and the interval optimization of the process parameters was carried out.The research results showed that the surface roughness is the most sensitive to changes in abrasive grain size,and the least sensitive to changes in abrasive belt linear velocity;the preferred range of abrasive grain size is 120#~150#,and the preferred range of abrasive belt linear velocity is 15~20 m/s,the preferable range of grinding pressure is 10~15 N.The theoretical method and experimental basis for the surface roughness control of titanium alloy grinding with abrasive belts are provided.
