FIELD: metallurgy. ^ SUBSTANCE: according to the invention, the method provides for item rotation around its axis and item machining by a tool making rotational movements and interpolated axial displacement. Preliminary, natural blade vibration frequencies are calculated for each line and angle of blade turning. Resonant behavior lines are then determined and tool rotation frequency is set for each above line based on a condition that dynamic component of generated roughness is minimised. In addition, blade rotation frequency for each line by the blade turning angle is set provided that the required speed of peripheral feed is ensured. ^ EFFECT: improved quality of machining. ^ 2 tbl, 1 ex |
