High performance virtual machining and optimization of aircraft parts

轻型航空框架是由实心铝块加工而成。铝以非常高的速度被铣削， 其低强度和耐热性。铝加工的生产率是颤振 由柔性工具/机床主轴或零件薄壁引起。细长端米尔斯经历严重的 颤振，导致报废昂贵的航空航天部件或损坏高性能机床。这 项目旨在减少铝零件的加工时间，同时满足公差要求。UBC将 验证其基于科学的零件质量预测算法，考虑灵活的部分， 机械加工零件通过选择最合适的刀具几何形状， 并虚拟模拟加工力和振动，以优化薄壁、柔性航空航天产品的铣削 零件.基础研究算法目前在不列颠哥伦比亚省的 (UBC)制造自动化实验室（MAL）在NSERC -普惠加拿大工业 研究主席。长期目标是将AVCORP带到NSERC赞助的基础但协作 研究项目。据了解，该项目将不会有任何时间提供F-35数据， 不符合ITAR要求的团队成员。

Light aerospace frames are machined from solid aluminum blocks. Aluminum is milled at very high speeds due to its low strength and thermal resistance. The productivity of machining aluminum is the chatter vibrations caused by flexible tool/machine tool spindles or thin walls of the parts. Slender end mills experiences severe chatter, which leads to scrapping costly aerospace parts or damage the high performance machine tools. This project aims to reduce the machining time of aluminum parts while meeting tolerance requirements. UBC will validate its science based part quality prediction algorithms by considering the flexible sections of the machined parts. Chatter free cutting conditions will be identified by selecting the most suitable cutter geometry, and virtually simulate the process forces and vibrations for optimal milling of thin walled, flexible aerospace parts. The fundamental research algorithms are currently studied at the University of British Columbia's (UBC) Manufacturing Automation Laboratory (MAL) under NSERC - Pratt & Whitney Canada Industrial Research Chair. The long term goal is to bring AVCORP to NSERC sponsored fundamental but collaborative research projects. It is understood that this project will not have any time where F-35 data is made available to members of the team that are not in compliance with ITAR requirements.
