At slower speed, the time available for heat dissipation in the tool material is high, hence the temperature of tool increases, which leads to a decrease in tool tip's strength, finally resulting in rapid tool wear.

At high speed, friction will be less hence it is good for tool life.

Carbide tool is used for HIGH to VERY HIGH speed accurate machining. So It wears out at low speed. Low speed is out of syllabus for carbide tool.

If increased the speed then more chance demaging the tool & workpiece.

Because the time available for wearing is more.

Because it is powder metallurgy technique and cobalt binder and its temperature is high.

Cemented carbide tools are used for machining stainless steels, carbon steels which are very hard.

In slow speed the contact between surfaces are more so it is obvious that at slow speed it will wear more.

Yes you are right @Naman as the speed decreases, the friction between the tool and W/P increases. So as the friction increases wear also increases.

Friction will be less at higher speeds.
