【摘要】 针对抛光整体叶盘根部与流道面工具损耗快、抛光效率低等问题,基于分区域抛光的思路从工具选型、轨迹优化、区域搭接及划分等方面开展研究。对抛光工具与轨迹进行优化;针对子区域之间的搭接问题建立优化模型并进行分析计算。在此基础上,基于分区域加工的方式对根部与流道面进行划分。工程环境下的抛光试验表明,分区域抛光将根部与流道面的工具损耗降低约30%,同时抛光效率提升约30%,从而推进了自动化抛光技术在整体叶盘上的工程化应用。更多还原

【Abstract】 Aiming at the problems of severe tool wear and low polishing efficiency in polishing the root and hub area of blisk, a study was carried out based on the idea of subregional polishing from the aspects of tool selection, toolpath optimization, area overlapping and division. Based on the idea of subregional machining, the polishing tool and toolpath are optimized; An optimization model for the overlapping problem between subregions is established and analyzed. After that, the root and hub area is divided based on the method of subregional polishing. Experiments in engineering environment show that the tool wear is reduced by about 30% and the polishing efficiency is increased by about 30%, which promotes the engineering application of automatic polishing technology in blisk.更多还原
