Cutting data
Excessive insert wear, such as flank wear must be avoided, as it
changes the clearance between the tool and the component wall,
which can cause vibration problems.
Cutting speed, v
c
Correct cutting speed will avoid built-up edge, which influences
surface finish, cutting forces and tool life.
• Excessive cutting speed can generate flank wear, which reduces
security and reliability, due to chip jamming, poor chip evacuation
and insert breakage, especially when machining deep holes
• Cutting speeds which are too low will generate built-up edge
• Uneven wear pattern will decrease tool life and surface finish, so
pay careful attention to wear pattern
• Workpiece material has a great impact on what cutting speed you
can apply
