The cylindrical portion 18 is preferably equipped with at least two opposing parallel fl ats 20 (only one visible in F IG .1) formed therein / on, on which a standard spanner wrench (not shown) may engage for installing or removing cutter 14 from shank 12, as discussed further below.
    [43] The exploded views of FIGS. 2 and 3 and detail views of FIGS. 4 and 5 show details of the portions of shank 12 and cutter 14 which form the coupling mechanism between cutter 14 and shank 12. More particularly, the coupling mechanism includes, as part of cutter 14: an outwardly protruding male threaded portion 22 extending opposite active fl uted portion 16; a radial aligner portion 28 disposed concentric to the longitudinal axis A and extending between the short cylindrical portion 18 and the threaded portion 22; and a fl at axial stop shoulder 30 which bridges the radial gap between the smaller diameter, radial aligner 28, and the larger diameter, short cylindrical portion 18. As shown in the illustrated example embodiment, shoulder 30 may disposed perpendicular to the longitudinal axis A. In other embodiments, shoulder 30 may be slightly inclined (up to +/- 3 °) to a reference drawn perpendicular to the longitudinal axis A.
    [44] [0044] generally smooth alignment bore 24 disposed concentric to longitudinal axis A, a The coupling mechanism also includes, as part of shank 12: a female threaded bore 32 extending from the alignment bore 24, and an axial stop 10 15 20 25 30 35 surface 34 disposed perpendicular to the longitudinal axis A at an end of shank 12 adjacent the alignment bore 24.
    [45] Aligner portion 28 is formed generally as a portion of a truncated cone and includes Referring to the detail view of cutter 14 shown in FIG. 4, the radial an outward facing circumferential surface 29 disposed at an angle Ö1 relative to longitudinal axis A. In example embodiments of the present invention, the angle 51 is generally in the range of about 1 ° to about 7 °. Altematively, radial aligner portion 28 may be of generally cylindrical shape (i.e., 81 = 0 degrees). In general, a truncated cone has been found to be preferable when the cutter 14 is coupled with steel shanks while the cylindrical shape has been found to be preferable when the cutter 14 is coupled with carbide shanks.
    [46] Shank 12 shown in FIG. 5, the alignment bore 24 is formed in a generally Referring to the cross-sectional detail View of an end portion of corresponding shape to aligner portion 28. In general, the diameter of the aligner portion 28 may be slightly larger (preferred for steel shanks ) or equal to (preferred for carbide shanks) than the diameter of the alignment bore 24.
    [47] [0047] shape to aligner portion 28, in the illustrated embodiment alignment bore 24 is also As the alignment bore 24 is formed in a generally corresponding formed generally as a portion of a truncated cone and includes an inward facing circumferential surface 25 disposed at an angle 52 relative to the longitudinal axis A. As the inward facing circumferential surface 25 of shank 12 generally cooperates with the outward facing circumferential surface 29 of cutter 14, in example embodiments of the present invention, the angle 52 is generally in the range of from about 0 ° to about 7 ° depending on the angle 81 of the outward facing circumferential surface 29.
    [48] Referring to FIGS. 4 and 5, threaded portion 22 of cutter 14 includes a number of threads 22a, preferably at least 4 (although other numbers may be employed), disposed at a first pitch P1 about longitudinal axis A and threaded bore 32 includes at least a corresponding number of female threads 32a disposed about longitudinal axis A at a second pitch P2, which is different than P1.
    [49] [0049] engaging the threaded portion 22 of cutter 14 with the threaded bore 32 of the shank 12 and subsequently rotating one or both of the cutter 14 and / or shank 12 Assembly of the modular cutting tool assembly 10 is performed by until the radial aligner portion 28 of cutter 14 is seated within the alignment bore 24 of shank 12 and the axial stop shoulder 30 of the cutter 14 abuts the axial stop surface 34 of the shank 12. The axial position of cutter 14 with respect to shank 12 is derived from the direct contact of stop shoulder 30 of cutter 14 with the axial stop surface 34 of shank 12. Once stop shoulder 30 and stop surface 34 are engaged, the coupling is preferably further tightened to a specified torque using a torque limiting wrench to avoid excessive tension of the cutter 14.
    [50] Mechanism between a 12 ”shank (shown in cross-section) and a 14” cutter of a FIG. 6 shows a detail view of another embodiment of a coupling modular cutting tool 10 ”. The cutting tool 10 ”may be of similar outward appearance to cutting tool 10, previously described, and cutter 14” and shank 12 ”interact in a similar manner as cutter 14 and shank 12 aside from the inclusion of a second radial aligner portion 40 disposed adj acent threaded portion 22 opposite radial aligner portion 28. When cutter 14 ”is coupled with shank 12”, such as shown in FIG. 6, the outward facing circumferential surface (not numbered) of the second radial aligner portion 40 engages the inward facing circumferential surface (not numbered) of a second alignment bore 42 formed in shank 12 ”adjacent threaded bore 32 opposite first alignment bore 24. In example embodiments of the present invention, radial aligner portion 40 is of generally similar, or slightly smaller diameter than the diameter of the second alignment bore 42. Also, the surface (not numbered) of second radial aligner portion 40 may be disposed at angles ranging from 0 ° to about 6 ° with respect to the central longitudinal axis A, while the surface (not numbered) of the second alignment bore 42 may be disposed at the same angle, or within a range of 1 ° -2 ° of the angle of the surface of the second radial aligner portion 40. Although shown having second radial aligner portion 40 in addition to radial aligner portion 28, it is to be appreciated that embodiments of the present invention may include o nly second radial alignment portion 40 without radial alignment portion 28. 10 15 20 25 30 35
    [51] Embodiment of a modular cutting tool 50 in accordance with the present invention FIG. 7 shows an exploded side view of another example which includes a shank 52 and a cutter 54 coupled via another coupling mechanism in accordance with the present invention. Shank 52 and cutter 54 may be of generally similar construction as shanks 12, 12 ”and cutters 14, 14” previously described and respectively include a female threaded bore 58 (including female threads 58a, 58b) and a male threaded portion 60 (including male threads 60a, 60b). However, unlike the embodiments previously discussed, in which different thread pitches on the male and female threaded portions were utilized to ditrubute stress more evenly throughout the threads when the two components were tightly threaded coupled together, the embodiment illustrated in FIG. 7 accomplishes a similar result by orienting the male and female threaded portions at different angles with respect to each other. For example, in the embodiment illustrated in FIG. 7, the threads 60a, 60b of the male threaded portion 60 are disposed at a first taper angle org (measured with respect to a reference disposed parallel to the central longitudinal axis A) while the threads 58a, 58b of the female threaded bore 58 are disposed at a second taper angle org (measured with respect to a reference disposed parallel to the central longitudinal axis A). More particularly, by disposing the female threads 58a, 58b at a second taper angle org greater than the first taper angle orC of the male threads 60a, 60b, a spatial relationship between the male and female threaded portions 58, 60 similar to that created by the use of different thread pitches as previously discussed is created even when the thread pitches PS and PC are the same. It is to be appreciated that such embodiment could also be utilized with different thread pitches PS and PC as an alternative to being used with portions having the same pitch.
    [52] [0052] is provided with a threaded bore for engaging a complementary male thread on the Although in the particular embodiments described herein the shank cutter, the reverse is also possible whereby the shank is provided with a protruding male threaded portion, and the cutter is provided with an internally threaded bore.
    [53] [0053] limited to the details of the foregoing illustrated embodiments and that the present It will be evident to those skilled in the art that the invention is not invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be tip embraced therein.
