异形长齿刀的加工过程原理和优势如下优点：
Compared with the axial gear shaving cutter, the radial shaving cutter has the following advantages:
1、加工效率高径向剃齿由于没有轴向走刀运动，只有径向进退运动所以加工效率比轴向剃齿高1-3倍。
1, processing efficiency high radial shaving because there is no axial knife moving, only the radial forward and backward movement so processing efficiency than the axial gear shaving high 1-3 times.
2、加工质量高，可以有效减轻甚至消除齿形中凹现象而且轴向剃齿齿面啮合属点啮合，而且节圆附近处单对齿啮合机会大，这样单对齿啮合时齿面压强增大，该处切除的余量也比其他部位切除的多，从而造成节圆附近齿形中凹。而径向剃齿齿面啮合为线接触，所以与普通剃齿相比增大了齿面啮合进给压力的承载面积，因而可以使剃齿剃除余量大小对啮合时啮合齿接触点数目的变化的敏感度下降，这样就可以减缓齿形中凹的形成。
2 and high quality of processing, can effectively reduce or even eliminate tooth profile concave phenomenon and axial gear shaving gear meshing is a mesh point and pitch circle near single of tooth meshing opportunity of big, so single pair gear meshing tooth surface pressure increases, the resection margin than other parts of the resection of multiple, resulting in the pitch circle near the tooth profile concave. And radial gear shaving surface meshing line contact, therefore, compared with the conventional shaving increases the tooth surface meshing of feed pressure bearing area, which can make shaving shaving allowance magnitude of meshing tooth meshing contact sensitivity to the change of the number of dropped, so that you can slow down the formation of tooth profile concave.
3、有利于降噪修形齿轮加工
3, is conducive to the processing of noise reduction and repair gear
根据汽车齿轮的不同用途及要求，为了降低啮合噪声，提高承载能力，多数汽车齿轮采用了特殊的齿形齿向修形——鼓形。对于轴向剃齿，除需要刀具齿形修形以外，还需剃齿机轴向运动机构具有鼓形运动功能，这样才能实现齿向鼓形修形。但由于轴向运动机构的复杂性和不稳定性，导致轴向剃齿的齿向修形很困难，主要表现为修形鼓形量调整困难、不稳定。而径向剃齿齿形齿向修形均是通过在剃齿刀齿部修磨时实现的，比较容易控制修形量，剃齿过程又比较稳定，所以剃后零件修形的稳定性比较好。
According to the different uses and requirements of the automobile gear, in order to reduce the meshing noise and improve the carrying capacity, the majority of automobile gear adopts the special gear tooth profile modification. For axial gear shaving, besides the need of tool profile modification, still need to shaving shaft drum motor function to the movement mechanism, so as to achieve tooth crown modification. However, due to the complexity and instability of the axial motion mechanism, it is difficult to form the axial profile of the gear shaving, which is difficult to adjust the shape and adjust the shape of the drum. And the radial shaving gear tooth profile modification is achieved through the shaving cutter teeth grinding, relatively easy to control the amount of repair, shaving process is relatively stable, so the stability of the shape of the part after shaving is relatively good.
4、齿刀耐用度相对较高
4, shaving knife is relatively high degree of durability
径向剃齿由于多刃同时切削，刀具刀刃的磨损比较均匀，与轴向剃齿刀比较，其平均单刃剃除的金属余量较小，因此磨损较小，耐用度也就相对较高。
Because of the multi blade cutting, the wear of the cutter blade is relatively uniform, compared with the axial gear shaving cutter, the average single blade shaving of the metal is smaller, so the wear is smaller, and the durability is relatively high.
