铝合金材质由于密度小,加工性强等特点被越来越多的应用于航空领域,大型薄壁铝合金零件多为航空发动机零件。该类零件的加工受到材质自身膨胀系数大和外界环境温度差异等因素影响较大,测量值和真实值之间存在误差,往往会导致零件加工超差或报废。本文主要针对以上两点影响因素进行分析研究,分析使用温度补偿技术对铝合金零件加工质量进行控制,最后将该技术实际应用到生产中。
Due to its low density and strong processability, aluminum alloy is more and more used in the field of aviation. Most of the large thin-wall aluminum alloy parts are aeroengine parts. The processing of such parts is greatly affected by factors such as large self-expansion coefficient of the material and differences in external ambient temperature, errors between the measured values and the actual values, which often result in over-processing or scrapped parts. This article mainly analyzes and studies the above two influencing factors, analyzes the use of temperature compensation technology to control the processing quality of aluminum alloy parts, and finally applies the technology to production.
