In this paper we present technical solutions to define the machining process to create good products specific for aerospace industry made of aluminium alloy extruded profile. Those parts have very tight tolerances and it is necessary to create a robust system to ensure repeatability of machining processes.
The major factor which affects our machining process is internal stress effect of the aluminium alloy extrusions. To determinate this influence were made several tests, using parts for aerospace industry, those parts were measured through coordinate measuring machine and all data was recorded for statistical analysis. Based on input data was determinate a technical solution to eliminate deviations caused by raw material internal stress for obtaining parts in tolerance.
Through several tests and recording all dimensions changes during the milling process, was obtained good products and was ensured repeatability of the machining process.
