Abstract

In today's world, interest in the aviation sector and developments within it continue to grow at an accelerated pace. With this increase, the demand for the production of components for unmanned aerial vehicles, passenger airplanes, or jet aircraft has risen correspondingly. However, due to the complex structure of aviation parts, the strategy employed during their processing is of significant importance. The distortion issue encountered in the machining of aviation parts, particularly in thin-walled components, leads to unwanted dimensional changes and significantly complicates the production of these parts.

This study aims to investigate the effects of different machining techniques on the widely used Al 7075 T7351 aluminum alloy in the aviation sector and to contribute the experimental results to both readers and the literature. In the experiments, samples of Al 7075 T7351 aluminum alloy with thicknesses of 1.00 mm, 1.20 mm, and 1.50 mm were processed using various machining strategies. According to the experimental results, the effect of tool strategy on thickness was observed to vary between a minimum of 0.67% and a maximum of 7.78%. Taking the average of the minimum and maximum values of the three samples, the average effect of the tool path strategy on surface roughness was found to be 55.46%, and its effect on parallelism varied between 37.50% and 112.50%.

Furthermore, it is believed that the methods presented in this study will contribute to solving similar problems in other industries, in addition to the aviation sector, in areas such as material selection, determination of processing parameters, and compliance of three-dimensional coordinate measurements (CMM) with standards.
