Along the length of groove, the width of each groove can be expressed as relative to the variation of the depth of each groove:

According to equation (2), when cutting blade 5301 has 90 ° of angle, the length groove width along groove is opposite Changed in trench depth with 2 multiple.For example, groove width increases by 2 millis for every 1 millimeter of increments of trench depth Rice.When cutting blade has 60 ° of angle, groove width is changed relative to trench depth with about 1.15 multiple.For example, For every 1 millimeter of increments of trench depth, groove width increases by 1.15 millimeters.When cutting blade has 30 ° of angle When, groove width is changed relative to trench depth with about 0.54 multiple.For example, every 1 millimeter of increase for trench depth For amount, about 0.54 millimeter of groove width increase.Therefore, each groove is cut into cutting tool and is provided has along ditch The groove of the slot length width of linear change and depth relative to each other.

According to equation (2), the width profile of the groove as shown in Figure 61 be can be similar in vpg connection according to Figure 62 Groove depth profile.Stated differently, since groove becomes more from an end wall 5250 or 5252 of groove to central part It is deep, so the width of groove also increases multiple associated with the angle of groove or cutting tool.Therefore, along trench length, ditch Groove width relative to trench depth variation and linear change, and the width profile of groove can be similar with depth profile.

According to equation (2), variation is linear caused by variation of the trench depth relative to groove width.However, Variation caused by variation of the trench depth relative to groove width can be constant or nonlinear.It can be used for making ditch One or more cutting tools of slot, so that trench depth changes relative to the variation of groove width according to non-linear relation. For example, variation caused by variation of the trench depth relative to groove width can be defined by following equation:

According to equation (3), groove width is subduplicate 2 times of trench depth:

Therefore, the relationship between the change in depth and change width of groove can be nonlinear.According to another embodiment, The depth and/or cross-sectional shape of groove are alterable, but the width of groove can be kept constant.For example, groove can have square Cross-sectional shape, wherein the depth of groove changes to the other end of groove from one end of groove, and the width of groove is kept constant. According to another example, the width of groove can the other end from one end of groove to groove keep constant, but the cross section of groove Shape and/or depth can change to the other end of groove from one end of groove.According to another embodiment, the depth of groove can be from The other end of one end of groove to groove is kept constant, and the width of groove changes to the other end of groove from one end of groove And/or the other end from one end of groove to groove is kept constant.

The depth 5355 of another example according to shown in Figure 66 and Figure 67, groove 5320 is (all along a part of groove Such as, the central part 5356 of groove) it can be constant.Therefore, the width 5380 of groove is also along the central part of groove 5356 Constant, as detailed above.For the groove 5320 for making Figure 66 and Figure 67, with constant at the central part 5356 of groove Depth 5355 use cutting tool (such as, cutting tool 5300), therefore at the central part of groove 5,320 5356 generate Constant width 5380.

In the center of mass of push rod there is the trench region of deeper and broader groove can provide higher expected ball speed, and More shallow and narrower groove near toe portion and heel part can provide lower expected ball speed.In addition, at the center of push rod Bigger groove width and depth at part can reduce the quality at the contact point with golf, from there through making each possibility Contact point at point mass it is equal come make across putter face ball speed normalization so that even if hit off center (toe, with It is portion, high or low) when, ball speed will with impinge upon putter face center on when be substantially the same.
