可转位端铣刀的刀具角度决定于刀片角度和镶装刀片的刀槽角度。刀槽角度又靠刀槽加工的正确调整来保证。因此,刀槽角度及刀槽加工的调整角计算,是可转位端铣刀设计、制造的主要问题之一。目前常常是根据设计图纸上标出的径向前角、刀槽斜角(或刀具刃倾角)和主偏角进行调整加工。理论计算和实际表明,由于没有考虑夹具(分度头)的调整原理,当刀具主偏角比较小,刃倾角绝对值较大时,采用上述近似调整法加工刀槽,会使实际刀具角度和设计角度在有些项目上相差很大,有时甚至 The tool angle of indexable end mills depends on the angle of the insert and the sipe angle of the insert insert. Slot angle by the correct adjustment of the groove to ensure that. Therefore, the angle of the sipe and the calculation of the adjustment angle of the sipe machining are one of the main problems in the design and manufacture of the indexable end mill. At present, it is often adjusted according to the radial rake angle, the groove angle (or the tool edge inclination) and the main deflection angle marked on the design drawing. Theoretical calculations and actual shows that, because the adjustment principle of the jig (indexing head) is not considered, when the tool main inclination angle is relatively small and the absolute value of the blade inclination angle is relatively large, the above-mentioned approximate adjustment method is used to machine the sipe to make the actual tool angle The design perspective varies widely on some projects, sometimes even
