In the field of research and manufacturing of control surfaces in robot components using 7075-T6 aluminum alloy, distortion during/after machining occurs because of the material removal forces and residual stresses and it affects robot path control. After the exact inspections, the main factors were found to be the machining strategy parameters in milling operation. This paper first presents flatness significance of robot chassis as a control surface for accurate path control, then discusses main causes of the Al-7075-T6 distortion, and offers methods of distortion reduction in material removal process by non-conventional milling strategy and finally optimum experiment parameters have been carried out. We have concluded this paper with a review of the main findings which will set the domain of our current and future research. Key words: Aluminum 7075 T6, distortion, control surface, robot, chassis.
