Definitions

  • the present invention relates to the field of cutting tools.
  • the present invention relates to a double-sided cutting insert for a drilling tool.
  • Peripheral milling also called “slab milling” creates a milled surface by using cutting inserts which are located on the periphery of the milling tool. Milling is usually accomplished by rotating the milling tool about a rotation axis parallel to the milled surface of the workpiece.
  • Indexable cutting inserts comprising a positive rake face geometry on both the axial cutting face and the radial cutting face of the insert are commonly employed in operations involving the use of a peripheral rotary tool.
  • An indexable cutting insert includes multiple cutting edges.
  • an indexable insert When a cutting edge that is in use is worn or damaged, an indexable insert can be rotated to assume a different orientation in the insert pocket of a tool holder so that a different cutting edge of the insert is presented to the workpiece.
  • the positive cutting geometry of the inserts reduces the necessary cutting forces and consequently reduces power consumption, resulting in a more efficient cutting operation.
  • Certain cutting inserts used in peripheral rotary milling operations are generally parallelogram-shaped (i.e., each has a generally parallelogram-shaped profile when viewed from a point above the top surface of the insert), with two long sides forming two main cutting edges and two short sides forming two minor cutting edges. These types of cutting inserts provide the capability of a larger depth of cut, although such inserts are not as strong as, for example, square-shaped cutting inserts.
  • Double-sided cutting inserts double the number of available cutting edges relative to single-sided inserts, thereby creating even greater benefits in cost reduction for both cutting tool end users and cutting tool manufacturers.
  • double-sided cutting inserts are most commonly used in stationary machining applications, such as turning or grooving, wherein the cutting tool is stationary and the workpiece being machined is rotating.
  • One of the major challenges in developing useful double-sided cutting inserts for a rotary tool is providing for a positive cutting geometry in a rotary machining application, such as hole drilling.
  • double-sided cutting inserts were only suitable for use in stationary machining applications. These applications, as noted above, require rotating the piece being machined while the cutting tool remains stationary. In recent years, due to demand for cost reduction and higher productivity from cutting tool end users, double-sided cutting inserts have been developed for milling applications.
  • a double- sided cutting insert for a drilling tool includes a top side, a bottom side, and at least one side surface interconnecting the top side and the bottom side and forming at least one cutting edge of the cutting insert
  • the top side and the bottom side comprise different external profiles and chip groove geometries and an identical inscribed circle, and each of the top side and the bottom side comprises four indexable cutting edges
  • a drilling tool system includes at least two double-sided cutting inserts
  • Each of the at least two cutting inserts includes a top side and a corresponding bottom side interconnected by at least one side surface
  • the bottom side and the top side of an insert are distinguishable from each other in shape
  • each of top side and bottom side of a cutting insert comprises at least four cutting edges which are 90° rotationally symmetrical about a center hole axis of the cutting insert
  • each of the at least two double-sided cutting inserts is connected to a mam shaft and is positioned to permit drilling activities
  • the main shaft is capable of rotational motion at speeds necessary to commence a drilling activity

  • the double-sided cutting insert of the present invention possesses different external profiles and chip groove geometries within the same inscribed circle for both the top and bottom faces, which also are referred to herein as top and bottom "sides" These differences allow the cutting insert to include twice the number of cutting edges relative to conventional inserts used for the same applications
  • This unique geometry not only doubles the number of cutting edges as compared to existing single-sided cutting inserts, but it also improves performance by applying different cutting geometries to different cutting regions along the radial direction
  • the present invention also allows for easier identification of the top side from the bottom side, as well as preventing the erroneous positioning of the cutting insert in the insert pocket
  • the different pocket geometry and size for the top and bottom sides on the same cutting insert aid in the prevention of erroneous positioning.
  • erroneous positioning is avoided through the differences between the top and bottom sides' external profiles and chip groove geometries.
  • the present invention also addresses a problem associated with drilling operations resulting from the variation in cutting speeds along the cutting edge in the radial direction.
  • the unique geometry of double-sided inserts according to the present invention is advantageous to addressing that problem.
  • non-limiting embodiments of a double-sided cutting insert according to the present invention may be achieved by using a composite structure that has a first side or face composed of a relatively tough cemented carbide grade and a second side or face composed of a more wear resistant cemented carbide grade.
  • Toughness may be defined as the ability of a metal to rapidly distribute within itself both the stress and strain caused by a suddenly applied load (e.g., the ability of a material to withstand shock loading).
  • the first side or face may have a cutting geometry including a uniform and free flowing chip breaker configuration design to suit the best machinability of work materials, thus favoring a lower cutting speed.
  • the second side or face may have a cutting geometry different from the first side or face and that is adapted to a faster cutting speed.
  • the cemented carbide grade of the first side or face may be, for example, any of carbide grades P20 to P40 having transverse rupture strength ranging from 1600 to 1950 N/mm 2 , grades M20 to M40 having transverse rupture strength ranging from 1900 to 2100 N/mm 2 , or grades K20 to K40 having transverse rupture strength ranging from 1950 to 2500 N/mm 2 (transverse rupture strengths according to Machinery's Handbook (26 th ed., Industrial Press, 2000)).
  • machining performance can be greatly improved by optimizing the combination of cutting geometry, carbide grade, and insert pocket locations on a drilling tool.
  • the present invention may be adapted to improve drilling performance if a tougher carbide grade is applied to the region of the side or face of the insert that is located close to the drill center. This, for example, increases the shock/impact resistance and also provides better wear resistance.
