· Tool life is the time a tool can be reliably be used for cutting before it must be discarded/repaired.
· Some tools, such as lathe bits are regularly reground after use.
· A tool life equation was developed by Taylor, and is outlined below,
· An important relationship to be considered is the relationship between cutting speed and tool life,
· Although the previous equation is fairly accurate, we can use a more complete form of Taylor's tool life equation to include a wider range of cuts.
