In this paper we present a research regarding adjustment machining accuracy on CNC machines with long axis for increasing positioning accuracy considering as a factor: thermal expansion effect. The research performed was made using laser equipment on industrial CNC machines used for production of aerospace components made of aluminium alloy extruded profile with length up to 12000 mm. Those parts have very tight tolerances and on milling process appear several factors that influence the repeatability of machining processes, the main one being the thermal expansion effect. The research results prove the improvement of positioning precision using the coefficients obtained from experimental measurements.
