Abstract
The design of advanced adaptive boring heads with automatic metal-cutting elements is developed. It allows setting up the heads for the finishing of inner cylindrical surface with the required accuracy, depending on the surface diameter, the value of tolerance field and its placement schemes. We describe the structure of the adaptive boring heads and how it works. To reduce shock loads when metal-cutting elements embedded for thrust adjustment screws, elastic dampers are used. On the basis of the settlement scheme analytical dependences for determination of the clearance gap between a thrust screw and a boring head regulating screw are developed. The value to process the holes of various accuracy with the same structural and geometrical parameters of metal-cutting elements is defined as well as the value and placement of tolerance field. The graphs of dependences of the value Δ on a nominal diameter of inner cylindrical surface of machined holes and various accuracy degrees are drawn. An image dependencies have practical value and can be used to directly configure heads of production units.
