Abstract
A cutting tool for cutting a material is provided with a cylindrical body having a cross-sectional diameter and a longitudinal rotating axis, and a plurality of teeth disposed on a circumference of the body, each tooth having a cutting edge and separated by a flute. The number of teeth is selected such that a ratio of the number of teeth to the diameter in millimeter (mm) is at least 0.75:1, that the cylindrical body is rotated with a tooth pass frequency of at least 400 teeth-per-second, and that the tool is used for machining in a way that all the material is removed at a rate of rough machining and in a manner to eliminate finishing pass.

A cutting tool for cutting a material, the tool comprising:
- a cylindrical body having a cross-sectional diameter and a longitudinal rotating axis;
- a plurality of teeth disposed on a circumference of the body, each tooth having a cutting edge and separated by a flute;
- and
- wherein number of teeth is selected such that a ratio of the number of teeth to the diameter in millimeter (mm) is at least 0.75:1, that the cylindrical body is rotated with a tooth pass frequency of at least 400 teeth-per-second, and that the tool is used for machining in a way that the material removal rates are about 65 cubic centimeters per minute per centimeter of flute length or higher (65 Cubic Centemeters/Min-Centemeter).
A method of cutting a material, comprising the steps of:
- providing a cutting tool comprising:
- a cylindrical body having a cross-sectional diameter and a longitudinal rotating axis;
- a plurality of teeth disposed on a circumference of the body, each tooth having a cutting edge and separated by a flute;
- and
- wherein number of teeth is selected such that a ratio of the number of teeth to the diameter in millimeter (mm) is at least 0.75:1;
- making a first cut in the material using a first tooth of the cutting tool, such that an amount of heat is conducted into the material;
- making a second cut in the material using a second tooth of the cutting tool, before the heat dissipates from the material;
- and
- wherein the heat softens the material and allows the second tooth to more easily cut the material.
