Hands on information
Insert size:
Do not use a a bigger insert size than necessary.
Nose radius:
Use a small nose radius, 0.2 mm is recommended
for finishing. A bigger nose radius will give
larger radial forces.
Geometry:
Use a sharp and positive geometry. A knife edge
insert is a good alternative
.
Insert style:
Use a T-style insert and a 90 deg. entering angle.
Tool overhang:
Always use as short as possible overhang.
Machining with tool overhang (from insert tip
to gauge line) more than 4 x the shank diameter,
use a damped tool, Silent Tools.
Chip evacuation:
Use cutting fluid to evacuate and to prevent
recutting of the chips. Chips in the form of
commas or determined spirals are the ideal.
