Abstract: A grinding process and wheel (2) are disclosed wherein any or all surfaces of a cutting blade (12) may be generated in a continuous grinding operation utilizing a single grinding wheel having a simple profile (4). A grinding wheel (2) having a grinding profile (4) comprising an inner conical surface (6) and an adjacent outer narrow substantially flat surface (8) is provided. The inner conical surface (6) rough grinds to generate a roughed blade surface and the adjacent outer narrow substantially flat surface (8) finish grinds the roughed surface to generate a finished blade surface. Computer numerical control (CNC) is utilized to control the relative movement of the grinding wheel (2) and cutting blade (12) along or about a plurality of axes. Inner (13) and outer (15) arcuate grinding surfaces may also be provided for rough grinding.

Abstract: Rotary grinding tool for straddle grinding of bevel and hypoid gears, and similar workpieces. The tool comprises two concentric grinding elements (12), (16) projecting in a common direction from one face of the tool. The tool is assembled from basic components (10), (14), (18) which can be easily disassembled. This permits accurate profile correction and surface renewal of the active grinding surfaces (20), (22) without interference with parts of the grinding wheel assembly which might otherwise be in the way of the dressing mechanimsm. In addition, the disassembled components can be used as separate grinding tools.

Abstract: A rotary dressing roller of the generating type and a method and apparatus for dressing a substantially cup-shaped grinding wheel for longitudinal curved tooth gears. The rotary dressing roller (40) is provided with a base portion (42) which is rotably mounted to the dressing motor (38) of a dressing apparatus (15). The dressing apparatus (15) is used to dress a grinding wheel (50). At the other end of base portion (42) there is provided a working portion (44) having an outer concave surface (45), an inner convex surface (46) and an outer cutting rim portion (47). The outer concave surface (45) and inner convex surface (46) of working portion (44) are shaped so as to allow dressing of the inside working surface (52) and outside working surface (54) of grinding wheel (50) by rotation of the rotary dressing roller (40) in a single direction.

Abstract: A tool (42), for dressing both the inside and outside working surfaces (92, 94) of cup-shaped abrasive wheels (28) used for grinding gears, is disclosed along with methods and apparatus for using the tool (42). The working portion of the dressing tool (42) has a cylindrical shape with an outside surface (82) parallel to its axis of rotation and a top surface (84) extending radially, to the axis of rotation. The apparatus orients the tool (42) relative to the grinding wheel (28) so that only the outer cylindrical surface (82) of the tool (42) is used to dress the inside working surface (92) of the grinding wheel (28), while only the top surface (84) of the tool (42) is used to dress the outside working surface (94) of the wheel (28). Formulas are provided for calculating the optimum radius of the cylindrical surface of the tool (42) for providing substantially equal effective relative curvatures between the tool (42) and each of the respective sides of the grinding wheel (28), thereby resulting in similar grinding characteristics being dressed into both the inside and outside working surfaces (92, 94) of the grinding wheel (28).
