Abstract
A method and apparatus for vibro-treating an object. The method includes the steps of controlling a relative displacement between a vibro-treating media and a surface area of the object to provide a vibro-treating effect; and, controlling movement of the object relative to a surface of the vibro-treating media while controlling relative displacement between the vibro-treating media and the surface area of the object, according to one or more pre-determined conditions, to provide a substantially even vibro-treating condition over the surface area of the object.
Claims20
A method of vibro-treating an object, the method comprising:
- providing a vibro-treating effect that comprises imparting a layer of compressive residual stress onto a surface area of the object, the vibro-treating effect provided by controlling a relative displacement between a vibro-treating media and the surface area of the object;
- and
- providing a substantially even vibro-treating condition over the surface area of the object, the substantially even vibro-treating condition provided by controlling substantially vertical movement of the object relative to a surface of the vibro-treating media while controlling the relative displacement between the vibro-treating media and the surface area of the object, the substantially even vibro-treating condition including providing a predetermined intensity over a predetermined coverage area of the object, the predetermined coverage area being a percentage of the surface area of the object that has been vibro-treated according to one or more predetermined conditions.
Vibro-treating apparatus comprising a controller configured to:
- provide a vibro-treating effect that comprises imparting a layer of compressive residual stress onto a surface area of the object, the vibro-treating effect provided by the controller controlling a relative displacement between a vibro-treating media and the surface area of the object;
- and
- providing a substantially even vibro-treating condition over the surface area of the object, the substantially even vibro-treating condition provided by the controller controlling substantially vertical movement of the object relative to a surface of the vibro-treating media while controlling the relative displacement between the vibro-treating media and the surface area of the object, the substantially even vibro-treating condition including providing a predetermined intensity over a predetermined coverage area of the object, the predetermined coverage area being a percentage of the surface area of the object that has been vibro-treated according to one or more predetermined conditions.
