Transformation Hardening
The main features of the laser as a heat source for transformation hardening are:(A) Clean energy source.(B) Energy is localised: no heat spillage.(C) Only surface layer heated: core properties are unaltered.(D) Low heat input: therefore low thermal distortion.(E) Fast process: therefore no oxidation. The process can be a final operation.(F) Self quenching: no water or oil sprays.(G) Easily automated: the laser fits naturally into a numerically controlled system with time sharing between work stations.
Using Bode plot calculate (a) Phase margin (b) Gain margin (c) Stability of closed loop system. The open transfer function of the system is
