Abstract: Methods and apparatus for removing swarf from machined components are described, in which a component is mounted on support means and the latter is vibrated in a manner to cause the component to be accelerated alternately in one direction and then the other, for a period of time. The acceleration is such as to cause the component to momentarily lift off the support means during at least part of each of the vibrations so as to bounce repetitively on the support means. The latter includes fingers adapted to engage non-critical regions of the components to reduce damage to machined surfaces or distortion of the machined component during vibration. A fluid flushing may precede and/or follow the vibration step.
