The profile of the cut surface is a combination of shape errors, undulations and surface roughness. Plastic deformation allows you to reduce the surface roughness without changing the shape and waviness errors achieved by boring. Combining the operations of fine boring and fine plastic deformation of the surface allows not only to improve the quality of the treated surface, but also under certain conditions provides the opportunity to simultaneously increase the processing performance. The best way to combine these operations in terms of productivity is when both the cutter and the deforming tool are located diametrically opposite in the same hole of the boring bar. Are proposed and described the engineering methods for calculating and selecting the geometry of the deforming tool, the feed and the strain force for combining technological operations of fine boring and fine plastic deformation of the wasted surface of the main holes of the ship’s hull mechanisms.
