본문내용
A = Break in period and measurable wear
B = Largest part of insert life and constant wear
C = Increasing rate of wear (wear land becomes larger and larger)
*
Controlling flank wear
- Reduce cutting speed
if normal flank wear caused by high cutting speed
- Increase cutting speed
if abnormal flank wear caused by low cutting speed
- Normally use a high speed oriented grade
- Apply coolant
*
Cratering
Cratering
-High heat and pressure in cut
-Chemical reaction causes
carbon loss
-Carbon becomes soft and
a crater develops
*
Controlling cratering
- Reduce cutting speed
- Normally use a high speed oriented grade
- Apply coolant
*
Deformation
