TECHNICAL INFORMATION
MACHINING OPTIMIZATION
BUILT-UP EDGE
(Adhesive Wear)
Description
The workpiece material is welded to the cutting edge. Normally
caused by low temperatures
Solutions
Increase cutting speed / Increase feed / Use more positive geometry
NOTCH WEAR
(Adhesive/Mechanic Wear)
Description
Result of adhesive or mechanical action. Chipping or localized
wear at the depth of cut line.
Solutions
Use more positive geometry / Reduce feed / Vary depth of cut
CRATER
(Chemical Wear)
Description
Happens on the rake surface. Normally the result of a
combination of a diffusion and abrasion wear mechanism.
Solutions
Decrease cutting speed / Check coolant direction / Use more
positive geometry
FLANK WEAR
(Abrasive Wear)
Description
Abrasive wear mechanism that happens on the cutting edge’s
flank. Not common in Lamina inserts.
Solutions
Decrease cutting speed / Check coolant direction.
PLASTIC
DEFORMATION
(Thermal Wear)
Description
Caused by cutting forces and too high temperature. Not
common in Lamina inserts.
Solutions
Decrease cutting speed / Decrease feed rate
THERMAL CRACKS
(Thermal Wear)
Description
Small cracks normally at 90° to the cutting edge caused by
temperature variation.
Solutions
Stabilize the temperature / Shut off the coolant
BREAKAGE
(Mechanic Wear)
Description
Most breakages happen because the wear development is not
seen in time.
Solutions
Check the tool holder / Check the tool overhang / Check the
Amax / Decrease feed and Vc / Apply more robust insert / Check
the run-out
