【課題】加工用工具および工作物を高速で同期回転させて切削加工により高精度な歯車を加工することができる歯車加工装置を提供すること。【解決手段】加工用工具42Bは、工具刃421BのピッチPbを、歯車Gの歯gのピッチPの2以上の整数倍となるように作製されている。このような加工用工具42Bを歯車加工装置1における切削加工時に使用することにより、工作物Wに同時に接触する加工用工具42Bの工具刃421Bの数を削減することができるので、切削抵抗を低減して切削加工時の自励振動の発生を抑え、歯車の歯すじ精度(歯すじのうねり)を向上させることができる。【選択図】図5 |

PROBLEM TO BE SOLVED: To improve the quality of a gear part by alternately assigning a front surface cutting part to related elements in response to the purpose. SOLUTION: In an effective area of a tool 0, a surface element 16 of the tool 0 is assigned to a surface element 14 of a work 2 so that the width thereof copes with 24 increments of the effective tool width. A surface element 17 of the tool 0 is assigned to a surface element 15 of the work 2. Width of the surface element 17 is equal to 19 increments of the effective tool width. This method is used for all surface elements. In the surface element 14, since the quantity of the material to be cut is more than other surface elements, the cutting material at a quantity more than that of other surface elements is provided to the surface element 16 so as to work the surface element 15 in the effective area of the tool 0. |

PURPOSE: To optionally change the shape of a tool and to form a continuous cutting edge by composing a cutting tool by the base material for tool mixed with abrasive grains having a sharp cutting edge.
CONSTITUTION: A cutting tool 10A for finishing forms a shaving cutter main body 13 by the blank stock consisting of the base material 12 for a tool of a casting or sintered metal, etc., for example, mixed with the abrasive grains 11 of a diamond, etc., for example, having a sharp cutting edge. Due to the base material 12 for tool having the edge projecting to a parallel land part 15 as well not only the edge 14 of a serration, finishing can be performed in succession. The finishing is enabled only by changing a cutter not only the exclusive shaving machine, in the case of roughing, for instance, and can be shortened in the stage. As for the manufacture of the above blank stock, the abrasive grains 11 of a specific ratio set in gradation are mixed into the base material 12 for tool and secured.

PURPOSE:To reduce manufacturing cost of a cutter and increse wear margin of a cutting edge to extend the life of the cutter by making arrangements such that a serration is formed deeply on only one tooth surface and only a tooth surface to be used of a gear to be machined is finish-machined. CONSTITUTION:Serration 6 is formed deeply only on the side of a tooth surface 4 at specified equal intervals along a shaft direction L of a shaving cutter 1 beyond the center of an edge line portion 8 reaching to a side vicinity of a tooth surface 2. Causing the tooth surface 4 engage with a tooth surface to be used of a gear to be machined, finish-machining is performed with a conventional method. On the other hand, the tooth surface without the serration 6 simply contacts a tooth surface not to be used of the gear to be machined. Since the cutter 1 machines the serration 6 only on one side, manufacturing cost can be reduced. Also, since the depth of the serration 6 on the tooth surface 4 can be made deeper than the case where the serrations are formed on both tooth surfaces, a dress-grinding margin is thicker. As a result, the life of the cutter is extended. |

PURPOSE:To heighten the extent of rigidity in a cutter and make a desired tooth profile securable with a simple tooth form as well as to make reduction in manufacturing cost and improvement in service life attainable, by attaching a reinforced member in a side end part of the tooth part of a shaving cutter. CONSTITUTION:Each of linglike reinforced members 13 and 14 is locked to both sides of a tooth part 12 of a cutter body 11 by a bolt 16 as interposing a clearance 15 in a dedendum part. If so, the tooth part 12 becomes a trihedral constraint beam, improving its rigidity, and deformation at the time of curring comes to nothing, so that it is able to engage a machined gear as in theory. And, chips are easily discharged out via the clearance 15. Therefore, a desired work tooth form is secured with a simple tooth form, and reduction in cutter cost and improvement in service life are well promoted. When toothing takes place, the bolt 16 is removed and these reinforced members 13 and 14 are removed as well, whereby it can be done as in an ordinary shaving cutter. |

PURPOSE:To avoid a middle-hollow cut phenomenon, by providing serration cutting edges only in half regions in one side and the other side tooth surfaces, in the case of a shaving cutter having the serration cutting edges in both tooth surfaces of each tooth. CONSTITUTION:A shaving cutter provides serration cutting edges 12 in a half region of a tooth surface 11a while serration cutting edges 12 in the other side half region of a tooth surface 11b in an opposite side. If a gear to be cut is machined by cross feeding said shaving cutter, the serration cutting edge 12 cuts only a tooth surface 4a in one side not cutting a tooth surface 4b in the other side. Next the shaving cutter, if it is cross fed in the reverse direction cutting the gear to be cut, cuts the tooth surface 4b in the other side by the serration cutting edge 12 formed in the left half region of a gear 11. By this shaving cutter, a middle-hollow cut phenomenon, in which a tooth surface in the vicinity of its center is more relatively cut, is also eliminated even when small contact ratio is provided for the gear to be cut. |
