In this paper we present a technological problem encountered in the machining accuracy of the parts for aerospace, made of aluminum alloy extruded profile with 7 meters length. Those parts have very tight tolerances and on milling process appears deviation due to thermal expansion effect, which influences the repeatability of machining processes. Through several tests and recording all values during the milling process, was defined through Taguchi method the main impact factors which have impact on the machined parts. Acknowledgement: Applying Taguchi method to control the thermal expansion effect on machining process of aluminum alloy extruded profile is the result of an experimental research conducted with the support of the machining department of SC Universal Alloy Corporation Europe SRL, Dumbrăvița.
