Milling head for a ball track milling cutter, ball track milling cutter having a milling head of this type, method for producing a cutting edge for a ball track milling cutter, computer program product for carrying out a method of this type, data carrier having a computer program product of this type, and grinding machine for carrying out the method

A milling head for a ball track milling cutter, the milling head comprising:

• an imaginary center axis;
• a first end being a working-side end and a second end being a clamping-side end opposite the first end when viewed along the imaginary center axis;
• and
• at least one geometrically defined cutting edge extending from a first cutting edge end facing the first end of the milling head in a direction of the second end of the milling head to a second cutting edge end facing the second end of the milling head extending along a cutting edge profile of the cutting edge,
• wherein at least one cutting edge is designed as an intersecting line between a rake face associated with at least one cutting edge and a first flank face associated with at least one cutting edge, and
• wherein at least one cutting edge is assigned a negative rake angle, a first clearance angle, and a wedge angle, a value of the negative rake angle in a first region of the first cutting edge end has a different value than in a second region of the second cutting edge end, the first clearance angle in the first region of the first cutting edge end has a different value than in the second region of the second cutting edge end, and the wedge angle along the cutting edge profile is constant.

A method for producing a cutting edge for a ball track milling cutter, the method comprising:

• producing the cutting edge by grinding directly on a main body of a milling head or on a cutting insert for a milling head, the cutting edge having a first end and a second end;
• wherein the cutting edge is produced as an intersecting line between a rake face and a flank face;
• wherein the cutting edge is formed with a negative rake angle having a rake angle value in a first region of a first, working-side end of the milling head facing the cutting edge end has a different rake angle value than in a second region of a second, clamping-side end of the milling head facing cutting edge end;
• wherein the cutting edge is produced with a clearance angle that has a clearance angle value in a first region of the first cutting edge end and a different clearance angle value in a second region of the second cutting edge end;
• and
• wherein the cutting edge is produced with a wedge angle that is constant along a cutting edge profile of the cutting edge between the first cutting edge end and the second cutting edge end.
