Abstract
The present invention provides an apparatus and method for processing a component surface by abrading the component surface using an abrasive surface. The apparatus comprises an abrasive surface which is rotatable about an axis extending parallel to said component surface. A support is provided for moving the abrasive surface or the component surface along a computer-generated toolpath and for applying a force between the abrasive surface and the component surface. The support increases the force between the abrasive surface and the component surface from a minimum force to a maximum force as the distance along the toolpath increases to maintain constant material removal from the component surface.
Claims15
A method of processing a component surface by abrading the component surface using an abrasive surface, said method comprising:
- rotating said abrasive surface about an axis extending parallel to said component surface;
- and
- moving said abrasive surface or said component surface along a computer generated toolpath whilst applying a force between said abrasive surface and said component surface,
- wherein the force between the abrasive surface and the component surface is increased from a minimum force to a maximum force as the distance along the toolpath increases.
An apparatus for processing a component surface by abrading the component surface using an abrasive surface, said apparatus comprising:
- an abrasive surface, said surface being rotatable about an axis extending parallel to said component surface;
- and
- a support for moving said abrasive surface or said component surface along a computer generated toolpath whilst applying a force between said abrasive surface and said component surface,
- wherein said support is adapted to increase the force between the abrasive surface and the component surface from a minimum force to a maximum force as the distance along the toolpath increases.
