Adjustment method and apparatus for a boring tool
First Claim
1. A method for machining an object, comprising:
- providing a computer numerically controlled boring machine, wherein the boring machine includes a translatable table and a translatable driving element, a static member, and a boring tool including a boring tool body and a cutting tool moveably coupled to the boring tool body;
coupling the boring tool to the CNC boring machine;
placing a surface of the boring tool in contact with the member;
moving at least one of the boring tool or the member after said placing to apply a force between the boring tool and the member sufficient to translate the cutting tool relative to the boring tool body; and
machining the object after said applying, wherein and said applying is by moving one of the table or the driving element relative to the other.

Abstract
Method and apparatus for adjusting the position of a cutting tool. In one embodiment, a boring tool includes a coupling member which is driven by a CNC boring machine, and a sliding tool holder which is slidably coupled to the coupling member. A frictional force resists sliding movement of the cutting tool holder. The frictional force is sufficient to retain the position of the cutting tool during machining operations. However, the frictional force is insufficient to resist a lateral force applied parallel to the direction of sliding, as used during adjustment of the tool position. In another embodiment, either a surface of the sliding tool holder or a surface of a frictional member are contoured with a shape that corresponds to a desired contour of a sidewall of a hole. During machining, a follower in contact with the contoured surface causes the cutting tool holder to slide laterally during machining, thus contouring the sidewall of the hole.
