Absract One of the key technological processes of production of the airframe of an aircraft is the manufacture of large-sized contour forming details such as “panel” and “fuselage shell”. To date, the most promising method of obtaining the required aerodynamic shape of such parts is the method of shot peen forming. It consists of processing the outer surface of a part with a stream of fast-moving shots, because of which a specific profile of micro roughness stays on the surface, characterized by numerous prints of fraction of different diameter and depth [1-5]. The grinding of the flap wheel is part of the forming process and improve the quality of the original surface. For the formation of large-sized surfaces, the scientists of INRTU have developed and introduced in the conditions of the Irkutsk aviation plant a unique installation for the shot peen forming– grinding of UDF-4 with CNC system [6, 7]. The primary, and the main difference of domestic development from foreign counterparts, is the division of the forming operation into smaller stages for easier process control. The development and improvement of grinding technology requires the development of appropriate methods and special software for it, which enables to automate the processing process.
