समीक्षा

The proposed AUSC boiler will have IN617 and IN625 parts/components in very high volume. However, nickel-based alloys are known as difficult-to-machine materials due to their high strength and low thermal conductivity which makes the cutting forces and cutting temperature very high, leading to a short tool life. Hence, the machining cost of these parts will be very high. Laser Assisted Machining (LAM), the material is locally heated and softened by an intense laser source prior to material removal, without melting or sublimation of the workpiece, as depicted in Figure. This enables the difficult-to-machine materials to be machined more easily and with low machine power consumption, which leads to an increase in material removal rate and productivity.
