A machine for machining a workpiece having a first central longitudinal axis passing through a workpiece plane that is disposed orthogonally relative to the first central longitudinal axis is provided. The machine includes a chuck or fixture on which the workpiece is disposable, a grinding spindle having a body, a wheel supporting an abrasive and an insulator electrically isolating the wheel from the body, the wheel being operable to remove material from the workpiece, the grinding spindle having a second central longitudinal axis about which the grinding spindle rotates, the second central longitudinal axis of the grinding spindle passing through the workpiece in the workpiece plane so as to create a continuous gear tooth on the workpiece and an electrochemical grinding (ECG) element configured to execute ECG processing on the grinding spindle and the workpiece to soften the workpiece as the gear tooth is being created by the grinding spindle.
A machine for machining a workpiece having a first central longitudinal axis passing through a workpiece plane, the workpiece plane being disposed orthogonal to the first central longitudinal axis, the machine comprising:
A gear comprising at least one of apex gap-less double-helical shaped teeth, apex gap-less herringbone shaped teeth and c-shaped teeth, the gear being machined by a process comprising:
A method of machining a gear, comprising:
