FIELD: mechanical engineering. SUBSTANCE: device for implementing the method has driving rollers 1 mounted for permitting movement. The rollers are set to allow for the diameter of the part to be worked. The calculation of the angles of setting of a cutting tool with respect to the bearing rollers is then performed. The calculation is performed to allow for deformation of the part due to its own weight negatively affecting forming. EFFECT: improved accuracy of working. 1 dwg
