Notch wear
Notch wear can be minimized with good
planning and some general advice:
•Useroundinsertswheneverpossible–
ensure the relationship between depth
of cut a
p
and insert diameter does not
exceed 25%.
•Use45ºenteringanglewhendepthofcut
exceeds 25% of iC.
•“Rolloveraction”inprogrammingto
eliminate the need for pre-chamfering and
minimize the notch wear. There will be
one contact point where the insert hits
the hard scale/surface at the corner of
the component and one different point at
the a
p
line.
•Rampingensuresthatanydamageis
spread out along the cutting edge. The
depth of cut should be varied between
25% iC to 15% (do not ramp to zero).
•Multiplepasseswithvaryinga
p
can be an
alternative.
•ForRCGX/RPGXinserts,programinboth
directions to utilise more edges on the
insert.
