Abstract
A method of machining keyways in shafts comprises the steps of aligning a central line of a spindle of a machine tool with a center line of a shaft to be machined, preliminarily machining a keyway in the shaft with keyway mill arranged on the spindle so as to retain a symmetrical allowance for a finishing machining of the keyways so as to machine walls of the keyway, finishing machining of radiused parts of the keyway at its both ends with a cross-feed of the mill so that a width of radiused parts is greater than a desired width of the keyway, and final machining the keyway with a self-aligning cutting tool mounted on the spindle so that it freely turns and is rectilinearly moved along the keyway.

A method of machining keyways in shafts comprising the steps of aligning a central line of a spindle of a machine tool with a center line of a shaft to be machined;
- preliminarily machining a keyway in the shaft with keyway mill arranged on the spindle so as to retain a symmetrical allowance for a finishing machining of the keyway so as to machine walls of the keyway;
- finishing machining of radiused parts of the keyway at its both ends with a cross-feed of the mill so that a width of radiused parts is greater than a desired with of the keyway;
- and final machining the keyway with a cutting tool which is self-aligned in the keyway and mounted on the spindle so that it freely turns and is rectilinearly moved along the keyway to finally machine the walls of the keyway.
