Abstract
A process of manufacturing sinusoidal shaped sealing rings is provided in which the rings are machined from solid bars of material. The rings are machined from the outer diameter of the bar by means of OD turning, trepanning or face-grooving tool and a parting tool. All of the tools synchronously oscillate precisely with the spindle by means of computer control to form the sinusoidal shape. The remaining material is then salvaged and retained at a smaller diameter than it started. The smaller diameter bar is then used to make smaller diameter rings at a later date.
