END MILL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240024969 titled 'END MILL

Simplified Explanation

The abstract describes an end mill with multiple curved teeth that have a constant cutting diameter along their entire length. These curved teeth are twisted in a reversible manner from rightward to leftward directions, providing cutting edges on the concave side of the curved shape.

  • The end mill has peripheral cutting edges with a constant cutting diameter.
  • The peripheral cutting edges are defined by curved teeth that are twisted in a reversible manner.
  • Each curved tooth is curved in an arcuate or arched manner around the outer circumferential surface of the end mill.
  • The twisted teeth provide cutting edges on the concave side of the curved shape.

Potential Applications:

  • Machining and milling operations in various industries such as automotive, aerospace, and manufacturing.
  • Cutting and shaping materials like metal, plastic, and wood.

Problems Solved:

  • Provides a constant cutting diameter along the entire length of the cutting edges.
  • The reversible twist direction of the curved teeth allows for efficient cutting in both rightward and leftward directions.
  • The curved shape of the teeth ensures a smooth cutting process.

Benefits:

  • Improved cutting performance and efficiency due to constant cutting diameter.
  • Versatility in cutting direction, allowing for more flexibility in machining operations.
  • Reduced tool wear and longer tool life.
  • Enhanced surface finish and accuracy in machining operations.


Original Abstract Submitted

an end mill includes a plurality of peripheral cutting edges having a cutting diameter that is constant over their entire cutting length. the plurality of peripheral cutting edges, which are adjacent to each other, are defined by curved teeth. each of the curved teeth is twisted in a twist direction that is changed irreversibly and smoothly from one of rightward and leftward directions to the other of the rightward and leftward directions in the entire cutting length so as to be reversed right and left on its way. each of the curved teeth has a curved shape curved in an arcuate or arched manner in a development view of an outer circumferential surface of the end mill around an axis such that a corresponding one of the peripheral cutting edges is provided on a concave side of the curved shape.
