Answer:
Cutting velocity.
Explanation:
Velocity of cutting affects more as compare to the depth of cut to life of tool.
As we know that tool life equation
[tex]VT^n=C[/tex]
Where T is the tool life and V is the tool cutting speed and C is the constant.
So from we can say that when cutting velocity increase then tool life will decrease and vice versa.
The life of tool is more important during cutting action .The life of tool is less and then will reduce the production and leads to face difficulty .
