INFLUENCE OF NON-PERPENDICULARITY OF THE CUTTING EDGES OF THE CUTTING HEAD ON THE SHAPE OF A CYLINDRICAL SURFACE PROCESSED BY TAP MILLING
The solution to the problem of chip removal in mass production of bodies of revolution by replacing turning operations with milling operations is shown. Known works and technological solutions proposed in them are briefly described. The most advantageous condition for milling bodies of revolution is an arrangement with a perpendicular arrangement of the axes of the workpiece and the cutting head. When machining using the tangential milling method, these errors are theoretically zero. However, errors in the manufacture of the tool can lead to a violation of the perpendicularity of the axis of rotation of the head and cutting edges. The paper gives an analytical calculation of possible processing errors.
