Abstract
A method for the manufacture of a component comprises the following steps, in sequence using an additive layer manufacturing process to build a three-dimensional net shape of the component; performing a first abrasive blasting operation on a region of a surface of the component; and performing a second abrasive blasting operation on the region. The angle of incidence of the abrasive on the surface in the first abrasive blasting operation is less than the angle of incidence of the abrasive on the surface in the second abrasive blasting operation.
