Problem Cause Solution
• high load on the cutting edge • add radial passes
• unproper cutting conditions • adjust cutting conditions
• chip evacuation • add sufficient coolant
• cnc program error • check cnc program
insert/tool breakage
• tool cutting load • add radial passes and/or
• tool overhang reduce cutting conditions
• clamp tool to the minimum
overhang length
tapered thread
• unsuitable cutting conditions • adjust feed/speed
flank wear catastrophic
failure • vibrations • reduce overhang as short as possible
• check tool and workpiece clamping
tool life limit
cutting time
short tool life
