Abstract (en)
[origin: EP3486034A1] In an embodiment, provided is a drilling method of forming a hole having a desired diameter in a fiber-reinforced plastic workpiece. The method includes disposing a resist layer, in which an opening having a diameter smaller than the desired diameter is formed, on the workpiece and ejecting blasting abrasives to the workpiece through the resist layer to cut a portion, which is exposed from the opening, in the workpiece while cutting a peripheral edge portion of the opening of the resist layer.
