Comments
Use 45° approach to
reduce chip thickness
and notching.
Use 45° approach to
reduce chip thickness
and notching – first
choice on good quality
forgings.
Use round inserts wher-
ever possible to minimize
notching.
For pocketing use
positive inserts.
Where large depths of
cut are possible.
Always use an entering
angle less than 75° if pos-
sible to reduce notching ie
Round RCMT, square
SNMG, CNMX.
For 90° entering angle.
