The invention provides a cone-shaped toothed tool with multiple cutting edges for high-rate tooth turning technology, which comprises a high-rate tooth turning tool body, a tool tooth disc group, and a fastening screw. The high-rate tooth turning tool body is a cone-shaped toothed tool. The number of teeth of the tool tooth disc group is identical to that of teeth of the high-rate tooth turning tool body, and the tooth profile of the tool tooth disc group is smaller than that of the high-rate tooth turning tool body. The tool tooth disc group is connected to the high-rate tooth turning tool body by means of the fastening screw. The tooth profile precision of the tool tooth disc group is lower than that of the high-rate tooth turning tool body. A single pass of the cone-shaped toothed tool with multiple cutting edges for high-rate tooth turning technology is equivalent to multiple passes of a traditional single-cutting-edge tooth turning tool; the previous rough machining multiple-pass procedure and fine machining pass procedure are merged into one procedure, thus allowing for improvement in machining efficiency of high-rate tooth turning and reduction in tool consumption cost.

The invention discloses a slotting cutter of an inverse-tapered spline straight gear and a designing method of the slotting cutter. Basic parameters of the slotting cutter comprise a tooth number Zo, a front angle gamma, a tooth crest rear angle alpha e, a reference circle diameter dfo and a reference circle pressure angle alpha fo, wherein the reference circle diameter dfo is equal to Zom, and m represents the modulus of the inverse-tapered spline straight gear; and the reference circle pressure angle alpha fo meets the formula. According to the slotting cutter of the inverse-tapered spline straight gear, an adopted inclined surface, namely a V-V plane, of a larger end of the inverse-tapered spline straight gear is designed according to the principle of meshing the bevel gear and the slotting cutter, the slotting cutter has higher tooth crest intensity, the problem of low separation and processing efficiency of double gears in the prior art is thoroughly solved, and the geometric accuracy of an inserted tooth profile of the inverse-tapered spline straight gear is guaranteed. The invention further provides the designing method of the inverse-tapered spline straight gear. With the adoption of the designing method, the high-accuracy and high-strength slotting cutter of the inverse-tapered spline straight gear can be obtained, and the accuracy of the inserted tooth profile of the inverse-tapered spline straight gear is improved.
