Abstract
A method and cutting tool for producing a hole or a recess in a workpiece which includes flat or curved sheets of fiber-reinforced composite material, metal or combinations thereof. The cutting tool has a shaft with a longitudinal axis and an axial cutting surface and at least one cutting edge disposed on the axial cutting surface and extending radially from the longitudinal axis with a gap between the radial inner extent of the cutting edge and the longitudinal axis. The method of use includes rotating the cutting tool about its longitudinal axis and also translating the cutting tool during rotation.
Claims45
A cutting tool for removing material in a workpiece, comprising:
- a shaft with a longitudinal axis and an axial cutting surface;
- and
- at least one cutting edge disposed on said axial cutting surface and extending radially from said longitudinal axis, a radial inner extent of said at least one cutting edge and said longitudinal axis defining a gap therebetween.
The cutting tool of claim 8, further including a countersink coupled with and positioned concentrical about said shaft.
A machine for removing material in a workpiece, comprising:
- a drive moveable in at least two directions;
- a cutting tool operatively coupled to said drive, including:
- a shaft with a longitudinal axis and an axial cutting surface;
- and
- at least one cutting edge disposed on said axial cutting surface and extending radially from said longitudinal axis, a radial inner extent of said at least one cutting edge and said longitudinal axis defining a gap therebetween.
A method of producing a hole in a workpiece, wherein the hole has a longitudinal axis which passes through a predetermined point on the surface of the workpiece and is oriented in a determined direction relative the workpiece, said method comprising the steps of:
- providing a cutting tool having a wear-resistant surface and an longitudinal axis, said cutting tool also having a cutting diameter which is substantially smaller than the diameter of the hole that is produced, said cutting tool including a shaft with a longitudinal axis and an axial cutting surface, at least one cutting edge disposed on said axial cutting surface and extending radially from said longitudinal axis, a radial inner extent of said at least one cutting edge and said longitudinal axis defining a gap therebetween;
- positioning said cutting tool eccentrically relative to the longitudinal axis of the hole;
- and
- simultaneously machining the workpiece in both an axial and a radial direction relative to the longitudinal axis of the hole, by simultaneously rotating said cutting tool around said longitudinal axis of said cutting tool, moving said cutting tool in an axial direction, and moving said cutting tool eccentrically around the longitudinal axis of the hole.
