For example, the groove making tool 430 can be the structure of the groove making tool 230 shown in FIGS. 2 and 3, the milling, grinding, polishing, or cutting tip diameter of the groove making tool is larger than the diameter The body of the groove making tool.

Referring to Figures 5 and 6, a close-up cross-sectional illustration of a representative end of a groove having a rounded portion at each groove end is shown. For example, the rounded portion 501 (Fig. 5) and the rounded portion 602 (Fig. 6). As briefly described above, several representative embodiments may include a rounded portion of the dome that is positioned outside the ball striking face of the golf club head. These various embodiments may further include a groove end corresponding to a first end that corresponds to the toe end of the golf club head face, and a second end that corresponds to the golf club The heel of the head.

Referring to the embodiment of FIG. 5, the representative groove 241 in the groove 240 has the side walls 585 and 586 being completely straight, while the top edges of the side walls 585 and 586 are parallel to each other until the rounded portion 501. At the rounded portion 501, one side wall is still substantially straight and the other side wall is curved. By way of example, Figure 5 shows how sidewall 585 remains predominantly straight at region 587, but how sidewall 586 is curved at region 588. The side wall 585 is no longer parallel to the side wall 586 at the rounded portion 501.

Region 587 has a sidewall 503 that is part of sidewall 585. The side walls 503 are completely straight. Region 588 has a sidewall 509 that is part of sidewall 586. The side wall 509 is curved in a rounded manner. In several other embodiments. The arc of the side wall 509 is a different shape and/or interacts with the side wall 503. Side walls 585 and 586, as well as side walls 503 and 509, meet at the bottom 508 of the groove 241. In various embodiments, the bottom 508 includes an arcuate axis along which the grooves 241 are symmetrical. The opposite end of the groove 241 can be a mirror image of the end shown in FIG.

Similarly, another representative embodiment shown in FIG. 6 shows the trench 641 whose sidewall 685 remains somewhat straight at the region 687, but the sidewall 686 is curved at the region 688. The sidewall 685 is no longer parallel to the sidewall 686 at the rounded portion 602. Additionally, similar to trench 241 in FIG. 5, trench 641 shown in FIG. 6 has a region 687 having sidewalls 603 which are part of sidewall 685 and are completely straight. The region 688 of the trench 641 has a sidewall 609 which is a portion of the sidewall 686 that is curved in a rounded manner. The trench 641 of FIG. 6 additionally includes a trench bottom 608. The opposite side of the groove 641 can be a mirror image of the end shown in FIG.

In various different representative embodiments, FIG. 7 shows a top view of a portion of the golf club head face 220 showing the rounded portion 501 of FIG. The cross-section of each of the three rounded portions 501 of the two sets is shown in FIG. The cross-sections 741, 742 and 743 of Figure 7 constitute three cross-sections of the first group, as shown in Figure 9; and the cross-sections 745, 746 and 747 of Figure 7 constitute the third group of three The cross section is shown in Figure 9. Cross sections 741 and 745 are two cross sections of region 707 of rounded portion 501, while cross sections 742 and 746 are two cross sections of region 706 of rounded portion 501. Similarly, cross-sections 743 and 747 are two cross-sections of region 705 of rounded portion 501.

As seen in Figure 9, the cross-sections 741, 742, and 743 are completely proportional and symmetrical to each other. The cross-section 741 is taken perpendicular to the top edge of the side wall 503 in the region 707; and the cross-section 742 is taken perpendicular to the top edge of the side wall 503 in the region 706; likewise, the cross-section 743 is the side wall of the region 705 The top edge of 503 is taken vertically.

As otherwise shown in Figure 9, the cross-sections 745, 746, and 747 are not completely proportional to each other, but are symmetrical. The cross-section 745 is taken perpendicular to the bottom 508 of the region 707, and the cross-section 746 is taken perpendicular to the bottom 508 of the region 706. Similarly, the cross-section 747 is taken perpendicular to the bottom 508 of the region 705.

The cross-sections of the representative embodiment disclosed in Figure 7 are similarly applicable to the representative embodiment shown and described in Figure 6 with respect to that disclosed in Figure 5. Additionally, in the same embodiment or in various embodiments, the cross-sections 741-743 are not perpendicular to the bottom 508 or top edge of the side wall 509; the cross-sections 745-747 are not associated with the top edge of the side wall 503 or 509. Vertical.

The adjective "proportional" refers to the similarity of the shapes and relationships of the various representative reference members. In the same way, similar triangles have similar three angles, but different sides are long, so that similar triangles are proportional to each other. Similarly, in this specification, although the dimensions will be different (i.e., the length or height of the side walls), the entire shape is the same.

Since representative embodiments of various different grooves are discussed in this specification, it should be noted that the groove making tool 230 (Figs. 2 and 3) can be motivated to perform a single path from the golf club head face 220. The first end 214 to the second end 212 (or vice versa). The single row of grooves is substantially straight in the side walls, such as indicated by numeral 844 in Figure 8, which shows a symmetrical cross section of a representative groove.

In a different embodiment, a first asymmetric groove making tool can be primed for a first path; that is, from the first end 214 of the golf club head 220 to the second end 212 (or vice versa) And a second asymmetric groove making tool (which is different from the first asymmetric groove making tool) can be pulsed to perform a second path having a direction opposite to the first path. These at least two paths can produce grooves having relatively curved sidewalls, such as indicated by numeral 849 in FIG. Other embodiments may include a plurality of rows of paths to create a continuous wall of grooves and a single row of paths to create a curved wall of grooves. The representative embodiments disclosed in this specification can provide grooves that conform to the regulations and/or standards established by various golf standards organizations and/or government agencies, but all embodiments should not be so limit.

Turning now to Figure 9, Figure 9 shows several cross-sectional illustrations of the circular groove portions taken along the different line segments 9-9 of Figure 7. The member shown in Figure 9 shows several cross sections of a representative groove portion of a representative groove 240. The cross-sections 741-743 show that as each of the cross-sections 741-743 is taken perpendicular to the top edge of the side wall 503, as the cross-sections advance along the length of the groove Similarity or proportionality. Cross-sections 745-747 show that when each of the cross-sections 745-747 is taken perpendicular to the top edge of the bottom 508 and/or side wall 509, along with the cross-sections The dissimilarity or non-proportionality of the length of the groove advances.

10 and 11 each show a front view of representative golf club head faces 210 and 1110, each showing a groove 240 and 1140 on the head face 220. The nature of the trench fabrication technique described in this specification is such that the ends of the trenches are rounded. In terms of this trait. Figures 10 and 11 additionally show a groove end 1090 and a groove end 1190 in an oblique slope.
