机夹可转位硬质合金端铣刀与焊接硬质合金端铣刀相比,虽具有使用寿命长,制造成本低,使用方便等优点,但前者通常适用于较轻快的工序。实际切削深度t和每齿进给量S_z的分布(图1)表明:前者比后者平均值低1/2。因此必须改进机夹可转位硬质合金端铣刀的结构,提高其性能,扩大其使用范围。进行研究的重要方向之一,是提高夹固部件的刚度和强 Machine clip indexable carbide end mill compared with the welded carbide end mill, although with long life, low manufacturing costs, easy to use, etc., but the former is usually suitable for lighter and faster processes. The actual depth of cut t and the feed per tooth S_z (Fig. 1) show that the former is 1/2 of the latter. Therefore, it is necessary to improve the structure of the machine indexable cemented carbide end mill to improve its performance and expand its use range. One of the important research directions is to increase the rigidity and strength of the clamping parts
