摘要： A tool, for dressing both the inside and outside working surfaces of cup-shaped abrasive wheels used for grinding gears, is disclosed along with methods and apparatus for using the tool. The working portion of the dressing tool has a cylindrical shape with an outside surface parallel to its axis of rotation and a top surface extending radially, to the axis of rotation. The apparatus orients the tool relative to the grinding wheel so that only the outer cylindrical surface of the tool is used to dress the inside working surface of the grinding wheel, while only the top surface of the tool is used to dress the outside working surface of the wheel. Formulas are provided for calculating the optimum radius of the cylindrical surface of the tool for providing substantially equal effective relative curvatures between the tool and each of the respective sides of the grinding wheel, thereby resulting in similar grinding characteristics being dressed into both the inside and outside working surfaces of the grinding wheel.
摘要翻译：公开了用于磨削用于磨削齿轮的杯形砂轮的内外工作表面的工具，以及用于使用该工具的方法和装置。修整工具的工作部分具有圆柱形形状，其外表面平行于其旋转轴线，并且顶表面径向延伸到旋转轴线。该设备使工具相对于砂轮定向，使得只有工具的外圆柱形表面用于打磨砂轮的内部工作表面，而只有工具的顶部表面用于打磨砂轮的外部工作表面车轮。提供了用于计算工具的圆柱形表面的最佳半径的公式，用于在工具和砂轮的各个相应侧之间提供基本上相等的有效相对曲率，从而导致类似的磨削特性被穿入内部和外部砂轮的工作面。

摘要： An intricate profile is formed on the peripheral face of the grinding wheel of a surface grinder by moving two rotatable and differently shaped dressing wheels axially and sequentially across the face of the grinding wheel while shifting the grinding wheel vertically in timed relation with such movement to control the depth of cut of the dressing wheels into the grinding wheel. The dressing wheels are movable with the crossfeed carriage of the grinder while vertical movement of the grinding wheel during the dressing operation is effected by way of the wheelhead of the grinder. Both motions are controlled during the dressing operation by a computerized numerical control.
摘要翻译：通过沿着磨轮的表面轴向和顺序地移动两个可旋转且不同形状的修整轮，同时沿着这种运动的时间关系垂直移动砂轮来控制磨削轮，从而在表面磨床的磨削轮的周面上形成复杂的轮廓，以便控制修整砂轮进入砂轮的深度。修整轮可以通过研磨机的交叉进给架移动，同时在修整操作期间砂轮的垂直运动通过研磨机的砂轮头进行。通过计算机化的数字控制，在修整操作期间控制两个运动。

摘要： A dresser for roughening the surface of an abrasive wheel has a cutter means for rotation in contact with the abrasive wheel. The cutter means includes a plurality of cutter teeth mounted on a cutter shaft. Ball bearings at each end of the cutter shaft permit the cutter means to rotate freely when held against an abrasive wheel as the wheel is rotated. A pair of hexagonal bearing supports each define a bearing receiving recess for receiving the ball bearings mounted at each end of the cutter shaft. Each of the bearing supports also defines a threaded, bolt receiving opening. A dresser body defines a cavity receiving the cutter unit and slots on opposite sides of the cavity receiving the bearing supports. The dresser body has bolt holes extending from the exterior of the body into the cavity through each of the slots. The dresser body includes a dresser handle which permits the dresser to be manipulated manually. Cutter supporting bolts extend from the exterior of the dresser body through the bolt holes into the cavity and engage the threaded bolt receiving openings in the bearing supports. A pair of locating ridges on the exterior of the body extend parallel to the cutter shaft, permitting accurate location of the dresser on an abrasive wheel tool rest with respect to the abrasive wheel. In an alternative embodiment, a dresser mounting plate is pivotally attached to the dresser body and, further, pivotally attached to the abrasive wheel tool rest, such that the dresser may be quickly pivoted into position for dressing the abrasive wheel.
