Technique for the Development of the Technological Process for the Tightening of Aircraft Parts on CNC Presses

Abstract:

A method for creating a control program has been developed, which ensures the manufacturing of the details-cladding of the required accuracy and quality in the automated mode. The method is based on the choice of the optimal loading scheme, under which the deformation program is created, the values of the control coordinates of the press are calculated in accordance with the kinematic model of the press. As a result, a control program is obtained, which ensures a more accurate manufacturing of the part, with a minimum amount of finishing work. The presented method of calculation of the tightening process allows, on the basis of the details of the part, to determine the shape of the tightening punch, and also, if necessary, to adjust the existing tightening punch in order to ensure a more precise manufacturing of the part.
