Simulation and intelligent control during grinding process for difficult-to-machine materials in aerospace
【摘要】 近年来,钛合金、高温合金、金属间化合物、高强度钢等难加工材料凭借优异性能广泛应用于航空航天领域关键构件。磨削作为难加工材料及关键构件精密制造的终加工方法,对制造质量与生产效率具有直接影响。然而,由于材料的难加工特性以及磨削过程的复杂性,导致磨削过程极易出现磨削力大、磨削温度高、砂轮磨损严重以及加工质量差等问题。本文针对航空航天难加工材料,以磨削加工过程模拟与智能控制技术为主线,总结了磨削过程力、温度、砂轮磨损及表面完整性等方面的研究进展和现存问题。最后,本文针对当前研究存在的主要问题,对未来磨削过程模拟与智能控制技术的发展趋势进行了展望。
【Abstract】 The difficult-to-machine materials(e.g. titanium alloys, superalloys, intermetallics and high-strength steels,etc) have attracted increasing attentions in manufacturing the key components in aerospace fields in recent years, resulting from their superior mechanical properties. Grinding, as the final machining method, has been employed to fabricate those materials and the associated key components, playing an important influence in the manufacturing quality and efficiency. However, there are problems such as large grinding force and temperature, severe wear of wheels, and poor grinding quality, owing to the difficult machining property of those materials and the complexity of grinding processes.This paper summarized the research progresses and existed problems in view of the grinding force, the grinding temperature, the wheel wear and the ground surface quality. The research object was the difficult-to-machine materials in aerospace fields and the main discussion topics focused on the simulation during grinding processes and intelligent control techniques. Finally, the future development trends of grinding process simulation and intelligent control technology were prospected regarding the main problems existing in current researches.
