A grinding system with a coolant subsystem including a grinding tool having a grinding surface adapted to grind a part, a nozzle adapted to supply a coolant material, and an arm coupled to the nozzle and to the grinding tool and adapted to allow placement of the nozzle in multiple positions. Each of the positions of the nozzle is preferably substantially tangent to the grinding surface of the grinding tool, which optimizes the transfer of excess heat from the grinding tool and the part.

A method of machining a part including clamping the part on a chuck, while the part is clamped on the chuck, orienting the part with an OD-type grinding tool and grinding a ball track on the part, and while the part is still clamped on the chuck, orienting the part with a cutting tool and cutting an outer surface of the part.

The present disclosure is directed toward a tooling assembly for a machine having an automatic tool changing system. The tooling assembly includes a holder, a tool body, and an internal passage defined within and extending through the holder and the tool body. The holder includes a machine interface configured to engage with a spindle of the machine. The internal passage is operable to have a coolant fluid flow within, and has a stem channel and a curved channel extending from the stem channel.

A method for determining residual stress in a selectively hardened parts including an unhardened region adjacent to a hardened region is provided. The method includes obtaining a Barkhausen Noise (BN) value for the unhardened region and selecting a corresponding absolute residual stress value from a correlation between BN values and absolute residual stress values. The selected absolute residual stress value accurately estimates the absolute residual stress in the hardened region of the selectively hardened part. In variations of the method the unhardened region is surrounded by the hardened region, the hardened region is a laser hardened region and the unhardened region is not laser hardened.

A method for determining residual stress in a selectively hardened parts including an unhardened region adjacent to a hardened region is provided. The method includes obtaining a Barkhausen Noise (BN) value for the unhardened region and selecting a corresponding absolute residual stress value from a look-up table. The selected absolute residual stress value accurately estimates the absolute residual stress in the hardened region of the selectively hardened part. In variations of the method the unhardened region is surrounded by the hardened region, the hardened region is a laser hardened region and the unhardened region is not laser hardened.

A method for laser-hardening a shaft for a vehicle includes applying laser light energy in a repeating pattern to a journal surface. The method further includes, responsive to the repeating pattern being applied completely around the shaft, applying laser light energy to the surface in a pattern different than the repeating pattern to form an overlap surface pattern that defines a tapered ramp having a corresponding hardness less than a hardness corresponding to the repeating pattern alone.

An automotive shaft fillet treating method including laser hardening a green machined fillet surface to a uniform depth d to induce compressive stresses into the surface, the surface extending the entire length l between outer edges of two undercut regions of the fillet, and applying additional compressive stress to the laser hardened surface via fillet rolling such that the uniform depth d is maintained along the entire length l during a subsequent grinding operation.
