The operating area has at least one milling edge extending transversely to the circumferential direction (U) of an operating axis of rotation. At least one of the at least one milling edge includes at least one milling edge portion in which a milling edge profile (P), which is defined by the radial distance (F) between the milling edge and the operating axis of rotation along the milling edge, has a non linear progression. The milling edge in the milling edge portion has a chip space, which extends radially inward toward the operating axis of rotation in relation to the milling edge. The chip space has a chip space base that follows the milling edge profile (P) at least in portions in the milling edge portion with the non-linear milling edge profile (P).

Milling tool and production method for a milling tool

A tool and related method for the non-cutting production or reworking of a thread in/on a workpiece comprises a forming area which is rotatable about a tool axis (A), the forming area having a plurality of pressing lobes protruding or projecting radially outwards away from the tool axis (A) for producing or post-reworking the thread by pressing the pressing lobes into the workpiece surface. The pressing lobes are arranged in succession along a shaping curve which substantially spirally encircles the tool axis (A), and the pitch of the shaping curve corresponds substantially to the pitch of the thread to be produced or reworked. The pressing lobes form at least one pressing ridge, wherein adjacent to the at least one pressing ridge a flaring ridge with a lower height Hthan the height of the pressing ridge His formed.

Tool and method for forming a thread, in particular an internalthread

A method for forming a thread with a predefined thread pitch and with a predefined thread profile in a workpiece, in which a tool is used, wherein, during working movement, a thread generating region forms a thread, wherein the tool is moved during a second working phase further into the workpiece in the same forwards direction as in the working movement, as far as a reversal point, wherein the decelerating movement comprises a rotational movement in the same rotational direction as in the working movement, wherein during the decelerating movement, the axial feed movement is controlled in dependence on the rotational angle of the rotational movement of the tool and wherein the axial feed of the tool during a complete revolution, is smaller in terms of amount than the thread pitchat least during part of the decelerating movement and is zero at the reversal point.

Method for forming a thread, in particular an internal thread

A thread former for the chipless production of a thread has a plurality of pressing lands, which are each arranged at predefined separation angles (T) along a shaping curve. Each separation angle (T) is smaller than or equal to a predefined maximum separation angle (T). For nominal thread former diameters (Da) between 6 mm and 20 mm, the maximum separation angle (T) is determined such that the following condition: T=sin((a&#xd7;ND+b&#xd7;ND+c)&#xd7;2&#xd7;&#x3c0;); is met for i) 6&#x2264;ND&#x3c;10 where a=&#x2212;0.0008, b=0.00705, c=0.1325, y=2; ii) 10&#x2264;ND&#x3c;12 where a=1.7924/(2&#xd7;&#x3c0;), b=0, c=0, y=&#x2212;0.408; or iii) 12&#x2264;ND&#x2264;20 where a=0.751/(2&#xd7;&#x3c0;), b=0, c=0, y=&#x2212;0.104; wherein Tis the maximum separation angle and ND is the amount of the nominal thread former diameter (Da) measured in millimeters.

Thread former and method for producing a thread

A tool for the chipless production of a thread on a workpiece can comprise a forming region, which is rotatable about a tool axis (A), for the chipless production of an internal thread, wherein the forming region has a plurality of pressure studs, which project radially from the tool axis (A), for producing or finishing the thread by pressing the pressure studs into the workpiece surface. In one implementation, the pressure studs are arranged successively along a shaping curve that encircles the tool axis (A) in a substantially spiral manner, and the pitch of the shaping curve corresponds substantially to the pitch of the thread to be produced. Additionally, the pitch angle (t) between first and second pressure studs along the shaping curve differs from the pitch angle (t) between the second pressure stud and a third pressure stud that follows the second pressure stud along the shaping curve.

This invention relates to a screw tap which is rotatable about a rotational axis and has a number of thread-cutting teeth, which respectively have a radially outer tip cutter and are disposed mutually offset, with a predefined thread pitch, in an arrangement running spirally or helically around the rotational axis.
