Tool Wear 


Tool wear describes the gradual failure of the cutting tool due to regular machining. 


The three basic mechanisms of tool wear are:


Abrasion
Adhesion
Diffusion




Tool Life
 
Tool life is defined as the time period between two successive grinding of tool and two successive replacement of tool. 
 

Variables Affecting Tool Life
 
The variables that have a significant effect on tool life are:


Cutting conditions
Tool geometry
Tool material 
Work material 
Type of cutting fluid 
Cutting fluid application technique
