Abstract: A milling tool is disclosed. The milling tool may include an elongated body having a longitudinal axis and a plurality of cutting inserts. The cutting inserts may each have a cutting edge and a cutting radius and be coupled to the body and spaced along the longitudinal axis. One or more of the plurality of cutting inserts may be adjustable (e.g., mechanically adjustable) between first and second cutting radii. A difference between the first and second cutting radii may be at least 10 μm. The milling tool may include cutting inserts having a plurality of different cutting radii. The milling tool may be configured to have a length that spans an entire height of an engine bore. The cutting inserts having different radii may compensate for dimensional errors in an engine bore diameter that occur when milling a deep pocket.

Abstract: According to one aspect of this disclosure, a grooving tool is provided. The grooving tool has a body with a plurality of recesses. Plural inserts assembled into each of the recesses. The recesses include a cutting edge for forming grooves in an engine cylinder wall when rotated in one rotational direction. The insert also includes a peening surface extending in the opposite rotational direction from the cutting edge for deforming the upper edges of the grooves when rotated in an opposite rotational direction.

Abstract: Milling tools configured to increase surface roughness are disclosed. The tool may include an elongated body having a longitudinal axis and a plurality of cutting inserts coupled to the body and spaced along the longitudinal axis, each cutting insert having a cutting edge. In one embodiment, the cutting edges may have an orientation that is oblique to the longitudinal axis of the elongated body. Each cutting edge may have a first end having a greater cutting radius than a second end. The cutting edges may be offset from the longitudinal axis of the elongated body by an offset angle. In another embodiment, the cutting edges may have a textured or rough surface profile. For example, the cutting edges may have a mean roughness (Rz) of at least 7.5 μm. The milling tools may increase the surface roughness of a milled engine bore to facilitate a subsequent rough honing process.
