PROCESS FOR MACHINING PARTS IN THE FORM OF A REVOLUTION BODY ON A MACHINE TOOL USING A ROTARY CUTTING TOOL, AND WORKPIECES ACCORDING TO SAID PROCESS

摘要

For machining bodies of rotation, the setting angle ( phi ) of the plane of the cutting edge (2) of the bit (1) and the distance (H) between the axis of rotation (3) of the bit (1) and the reference plane (5) are chosen such that the difference in the distances (11 and 12) between the points (7 and 9) of the cutting edge (2) and the axis of centres (6) of the machine tool is equal to or greater than the amount ( DELTA ) of the elastic deformation of the material. In this case, the points (7 and 9) lie in a plane (8) which runs through the axis of centres (6) of the machine tool and the apex (7) of the cutting edge (2) of the bit, and on different sides of the axis of rotation (3) of the bit (1).
