    • A a golf club head with a variable thickness face plate having a central thickened region surrounded by a transition region tapering from the central thickened region to a thinner peripheral region. The golf club head is made by locating a ball end mill revolving about an axis generally normal to the inner surface of the face plate at an initial location on a circumferential intersection between the outer edge of the central thickened region and a transition region. The inner surface of the face plate is machined by moving the revolving ball end mill in a radial direction outwardly toward and through the transition region and the peripheral region to machine the inner surface of the face plate creating a tool channel having a width as the ball end mill traverses the transition region and thereby vary the thickness of the face plate in the tool path. The ball end mill is then raised in a direction normal to the surface of the face plate and relocated to a subsequent location on the circumferential intersection adjacent to the previous tool channel. The steps of machining, raising and relocating the ball end mill are repeated until the end mill has traversed the entire circumference of the circumferential intersection. In preferred embodiments, the machining step may vary the thickness of the transition region along a variable path, which may be a straight line, a curved line, or any other suitable path.
    • 一种具有可变厚度面板的高尔夫球杆头,其具有由从中心加厚区域逐渐变细到较薄外围区域的过渡区域包围的中心增厚区域。 高尔夫球杆头是通过在中央加厚区域的外边缘和过渡区域之间的圆周交叉点上的初始位置处定位围绕大致垂直于面板的内表面的轴线旋转的球头立铣刀来制造的。 面板的内表面通过使旋转球头立铣刀在径向方向上向外移动并穿过过渡区域和周边区域来加工面板的内表面,从而形成宽度为球的刀具通道 端铣刀穿过过渡区域,从而改变工具路径中面板的厚度。 然后将球头立铣刀沿着垂直于面板表面的方向升高,并重新定位到邻近先前工具通道的圆周交叉点上的后续位置。 重复加工,升高和重新定位球头铣刀的步骤,直到端铣刀已经穿过圆周交点的整个圆周。 在优选实施例中,加工步骤可以改变沿着可变路径的过渡区域的厚度,其可以是直线,曲线或任何其它合适的路径。
