А., Ph.D. student, e-mail: mrsi@bti.secna.ru Firsov A. M., Ph.D. (Engineering), Associate Professor, Head of Department, e-mail: mrsi@bti.secna.ru Biysk Technological Institute, Branch of Polzunov Altai State Technical University, 27 Trafimova st., Biysk, Altai region, 659305, Russian Federation Abstract The paper is devoted to errors that affect the hole shape accuracy of thin walled body parts with variable wall thickness. It is shown that the total deviation of the hole shape depends on thermal deformation. In this paper a method for the technological process control which includes thermal deformation compensation at the TP design stage using artificial neural networks is proposed. Studies of deformations were carried out with the aid of computer modeling in the finite element analysis system ANSYS. Keywords thermal deformation, body parts, accuracy of shape, technological support, artificial neural networks
