As per my knowledge, the only thing we know about the carbide tools tha they works better in compression and worst in tension, in higher working speed, compressive forces are more but the carbide tool can withstand that forces because of its property that it works well in compression but working in slower speed led to breakage of the carbide tool as tension forces are more there.

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.

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.

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.

Because Time required for wear is more. It is made by powder metallurgy it is used to machining of steel. It is very Hard.

It is a powder metallurgy technique so slow cutting the heat generation is too high so metal remove rate is high.

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

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

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