Abstract
A method of producing a hole in a fiber reinforced composite material workpiece includes the step of providing a cutting tool having a shaft, a cutting head, and an axis of rotation. The cutting head has a diameter which is substantially smaller than the diameter of the hole that is produced. The shaft has a diameter which is substantially smaller than the diameter of the cutting head. The cutting head has a height which is substantially smaller than the depth of the hole that is produced. The cutting tool is oriented such that the axis of rotation of the cutting tool is substantially orthogonal to the surface of the workpiece. The workpiece is simultaneously machined in both an axial and a radial direction relative to the longitudinal axis of the hole, by simultaneously rotating the cutting tool around the axis of rotation, moving the cutting tool in an axial direction, and moving the cutting tool eccentrically around the longitudinal axis of the hole.
