Tool Wear Defined:
'Tool wear is the gradual failure of cutting tools due to regular operation. Tools affected include tipped tools, tool bits, and drill bits that are used with machine tools.
Types of wear include:
Flank wear in which the portion of the tool in contact with the finished part erodes. Wear can be described using the Tool Life Expectancy equation.
Crater wear in which contact with chips erodes the rake face. This is somewhat normal for tool wear, and does not seriously degrade the use of a tool until it becomes serious enough to cause a cutting edge failure. Can be caused by spindle speed that is too low or a feed rate that is too high. In orthogonal cutting this typically occurs where the tool temperature is highest. Crater wear occurs approximately at a height equaling the cutting depth of the material. Crater wear depth (t0) = cutting depth
Notch wear edge wear, in drills, refers to wear to the outer edge of a drill bit around the cutting face caused by excessive cutting speed. It extends down the drill flutes, and requires a large volume of material to be removed from the drill bit before it can be corrected.
Edge Rounding, Edge rounding refers to the radius increase of cutting edge of the tool due to material removal. Edge rounding combines wear contribution…'
