Abstract
A rotary shell cutter tool can include a cylindrical body defining a center axis extending through the body that further defines a cutting face, a cutting insert, and a cutting recess defined in the cutting face that extends axially into the cylindrical body from the cutting face. The cutting recess can be configured to receive the cutting insert. The rotary shell cutter tool can be configured to have replaceable cutting inserts which can be attached to the shell cutter via a flexure.
Claims38
A rotary cutting tool comprising:
- a substantially cylindrical body defining a center axis extending therethrough, the body comprising a cutting face;
- a cutting insert;
- and
- a cutting recess defined in the cutting face, the cutting recess extending axially into the substantially cylindrical body from the cutting face, the cutting recess configured to receive therein the cutting insert.
A cutting tool comprising:
- an annular body rotatably centered about an axis, the body defining a distal end and a proximal end, the proximal end comprising a cutting face;
- a plurality of cutting recesses defined circumferentially about the cutting face, each cutting recess defining a void;
- and
- a plurality of cutting inserts, each cutting insert disposed in the void of each cutting recess, each cutting insert sizably configured to form an interference fit with each void.
A method of securing a cutting insert to a rotary tool, the method comprising:
- providing a rotary cutting tool comprising a substantially cylindrical body, a cutting face, a cutting recess, a cam tool, and a first cutting insert;
- engaging the cam tool with the rotary cutting tool at the cutting recess;
- articulating the cam tool to elastically deform the cutting recess and release a clamping force;
- replacing the first cutting insert with a second cutting insert;
- and
- releasing the cam tool.
A method of securing a cutting insert to a rotary tool, the method comprising:
- providing a rotary cutting tool comprising a substantially cylindrical body, a cutting face, a cutting recess, a cutter bolt, and a first cutting insert;
- articulating the cutter bolt to selectively tighten or loosen the cutter bolt to modulate a holding force provided therefrom;
- disengaging the cutter bolt with from the cutting inter;
- replacing the first cutting insert with a second cutting insert;
- and
- reengaging the cutter bolt with the cutter insert.
