... profile correction third-order correction modified roll motion The helical shaping cutter resembles a helical gear but has addendum modifications along the face width (i.e., the lengthwise direction) to provide an appropriate side clearance angle and a rake angle on the front cutting face...

... resharpening depth of the shaping cutter can be determined by this topography. The numerical result indicates that third-order correction reduces the profile error of the major cutter enveloping gear to submicro and extends the resharpening depth. 30 03 2008 14 01 2009 07 04 2009 cutting...
