Annotation. Increasing drilling efficiency is an important task in mechanical engineering. An improved method is proposed for drilling a part in metal, which is elastically deformed in the area below the proportionality limit before drilling, which ensures that other dimensions remain unchanged. Empirically, the dependences of the axial force were obtained when drilling blanks from duralumin D16 in an elastically stressed state. These dependencies allow you to select the correct cutting conditions when drilling parts from D16 duralumin.

Annotation. Modern methods of restoring car body parts include many interrelated operations performed in accordance with certain requirements. The repair, as a rule, is controlled by both the organization that carried out the repair and the owner of the car. Often after the repair, there are disagreements in assessing the quality. The article describes a technique for determining the places of damage hidden from observation without using a destructive method. Based on the application of non-destructive testing methods and analysis of the chronology of events, conclusions were drawn about the cause of the formation of convex deformations of the hood. The article may be useful to specialists working in the field of body repair, as well as experts assessing the quality of body repair.
