<p>Whirling method for machining round material or the like, with a clamping device (19, 19') for the workpiece (18) and a whirling attachment (1) for the machining, the workpiece (18) being held stationary with regard to its longitudinal centre axis (22), and the whirling tool (16), designed as an annular cutting tool with an internal tooth system (17, 33), being able to traverse on a compound slide (6) movable in a perpendicular plane (38) to the longitudinal centre axis (22), and a cutting movement of the whirling tool (16) taking place on account of a displacement of the pitch-circle centre point (24, 24') on a pitch-circle centre point path (27), characterised in that a displacement of the pitch-circle centre point (24') along a curve (31) is at the same time in a CNC-controlled manner on the linear plunging movement of the pitch-circle centre point (24) into the workpiece (18) (Z-axis), the curve (31) meeting the pitch-circle centre point path (27) after a rotary angle alpha . …<IMAGE>… </p> |
