Abstract
A cutting tool with a plurality of cutting elements connected to a support structure wherein a portion of the support structure is configured to flex or bend based on the rotational frequency of the cutting tool. The rotational frequency of the cutting tool is a product of the design and composition of the tool.
Claims23
A cutting tool comprising:
- a centralized shaft having a central axis with a first end and a second end wherein the first end is configured to connect to a rotational element such that the cutting tool is rotatable about the central axis at a rotational frequency;
- a plurality of resiliently compliant support element connected to the centralized shaft wherein the resiliently compliant support element moves in correlation to the rotational frequency at a preferred resonance frequency, wherein each of the plurality of resiliently compliant support elements extend radially outward from the central axis such that they are elongated elements having a first portion connected to the centralized shaft and a second portion, and wherein each of the plurality of resiliently compliant support elements rest in a resting plane when not rotating and where each of the plurality of resiliently compliant support elements flex out of plane when rotating;
- and;
- a plurality of cutting elements wherein each of the plurality of cutting elements corresponds to at least one of the plurality of resiliently compliant support elements and is connected to the second portion thereof, wherein the cutting element produces a hammering effect as a result of movement from the resiliently compliant support element.
