FIELD: mechanical engineering. SUBSTANCE: method comprises machining A pipe by the tool head provided with two rotatable flexible tools. The working surfaces of the tools are answered to the surface to be machined. The tool head is set in rocking by an angle 5-15 about the axis that is coincident with the axis of the part to be machined. The part is set in forward motion along the axis of the rocking. The radius of the tool is less then the radius of curvature of the portion of a pipe to be machined at least by a factor of 1.2. EFFECT: simplified method. 2 dwg
