Asymmetric Setting Element for Cutting Tool Clamping

The patent applies asymmetry by forming a contour on the cylindrical basic body that deviates from perfect cylindrical symmetry. This contour, which may include flat regions, grooves, or other asymmetric features, creates an asymmetric cross-section that prevents rotation while the element remains guidable in the setting element guide. The asymmetric contour ensures that the setting element can only be inserted in the correct rotational position, thereby preventing undesirable rotation during tool change while maintaining automatic orientation capability.

The patent applies local quality by maintaining a substantially cylindrical basic body shape for the majority of the setting element, which provides the necessary automatic orientation capability. However, a specific local region of the cylindrical surface is modified by forming an asymmetric contour, which prevents rotation. This localized modification ensures that the bearing surfaces maintain adequate contact area for precise automatic orientation while the asymmetric contour feature prevents rotational movement during tool change.

The asymmetric contour formed on the cylindrical basic body prevents the setting element from rotating in the guide during tool change. This ensures that the active surface of the setting element consistently bears flush against the cutting-body rear wall in a planar manner, rather than point-like or one-sided contact. The asymmetric feature maintains proper orientation and contact throughout operation, preventing both rotation and precision setting errors.
