对于尖齿螺旋铣刀螺旋槽的加工,目前普遍采用的方法,多是以现有的一些书籍中介绍的理论为依据,使用双角刀进行加工。但是实践表明,使用双角刀加工螺旋角大于40°的螺旋铣刀,会产生明显的内切现象。在实际加工时,虽然可以用调整刀具错位量的方法使螺旋铣刀的齿形有所改善.但并不 Spiral helical cutter spiral groove machining, the current commonly used methods, mostly based on the existing theory described in some books, the use of double-angle knife for processing. However, practice shows that the use of a double corner knife to machine a helix cutter with a helix angle greater than 40 ° produces a significant internal cut. In the actual processing, although the tool can be used to adjust the amount of misalignment of helical cutter tooth profile improved, but not
