<p>A computer controlled machine for forming longitudinally curved tooth bevel and hypoid gears having a minimum number of movable machine axes for setup and operation. The movable axes include three rectilinear axes (X, Y and Z) and three rotational axes (T, W and P). The rectilinear axes are arranged in mutually orthogonal directions. Two of the rotational axes (T and W) provide for rotating tools (26,27) and work gear (42,43), respectively. The third rotational axis (P) provides for adjusting the relative angular orientations of tool axis (T) and work axis (W). Pivot axis (P) is positioned with respect to both tool axis (T) and work axis (W) at fixed inclination angles. A method of operating the computer controlled machine provides for controlling the movable axis (X, Y, Z, T, W and P) in response to setup and operating parameters of conventional bevel and hypoid gear generating machines. <IMAGE></p> |
