Tube-spinning process is an effective method for manufacturing long thin-wall tubes with precision dimensions and desired mechanical property. The main objectives of this research deal with the influences of major process parameters of thermomechanical tube-spinning process such as preform thickness, thickness reduction, mandrel rotational speed, feed rate of rollers, solution treatment time, and aging treatment time on internal diameter growth and wall thickness changes for manufacturing of 2024 aluminum spun tubes using design of experiments. Experimental results are analyzed by analysis of variance and empirical models of internal diameter growth and wall thickness changes are developed. It is found that lower thickness reduction with thinner preform thickness, higher feed rate of rollers, slower mandrel rotational speed, and lower solution treatment time have advantages for obtaining smaller internal diameter growth and wall thickness changes.
