What is Cutting?
If we know the condition of a cutting edge during machining. The cutting edge cuts the workpiece and chips are produced. The temperature at the top of the cutting edge becomes as high as 800°C because of impact and friction.
Cemented carbide grades that can withstand these high temperatures are the most successful.
Carbide formed into different configurations are the most popular, and they are called indexable inserts. Indexable inserts are used for various shapes of holders and selected according to shape of the workpiece and cutting mode, so it is useful and popular nowadays for metal cutting process in industrial area.
