A method of machining a surface of a component. The method comprises scanning the surface of the component to obtain scanned electronic 3D data representing the scanned surface of the component locating a surface defect of the scanned surface and identifying a defect region that surrounds and includes the surface defect, and providing electronic 3D data representing a patch having the desired shape of the defect region. The method also comprises transforming the patch to generate a tooling path for repairing the surface defect. The transformation comprising translating a plurality of nodes of the patch. The translation distance of each node based on the distance of that node from an origin node of the patch. The method further comprises machining the surface of the component according to the generated tooling path.

In a work polishing apparatus, a polishing head including a head base portion, in an upper portion, to which a vertically movable and rotatable head shaft is fixed, and a holding member, in a lower portion, having a lower surface on which a work is held, is provided with, on the upper surface side of the holding member, a vertically movable partitioning portion and first and second fluid chambers respectively on the inner and outer circumference sides of the partitioning portion. Pressure in the first fluid chamber and in the second fluid chamber can be independently increased or decreased. The partitioning portion can be lowered at least to a position where the first fluid chamber and the second fluid chamber are partitioned such that a pressure difference can be produced between the interior of the first fluid chamber and the interior of the second fluid chamber.
