Optimized Surface Roughness of Grinding and Polishing in Blisk

以整体叶盘作为加工对象,为提高其叶片表面加工质量,降低表面粗糙度,展开整体叶盘磨抛工艺参数(如砂带粒度、砂带线速度、进给速度)的优化。首先,进行整体叶盘数控磨抛试验,其次,应用信噪比优化磨抛工艺参数,最后,选最优工艺参数对整体叶盘进行磨抛试验,加工表面测量结果表明,整体叶盘表面粗糙度显著降低,满足叶盘表面加工质量要求。

Take blisk as research subjects,to improve surface quality of the blisk blade and reduce surface roughness,the paper carry out optimizing the blisk grinding and polishing process parameters,such as particle size,belt speed and feed rate.Firstly,conducted grinding and polishing experiment.Secondly,applied the method of signal to noise ratio to optimize the grinding and polishing parameter.Finally,select the optimized process parameters to conduct grinding and polishing test,the result shows that the surface roughness of blisk is significantly is lower to meet the requirements of processing quality.
