Measurement automation is the essential requirement for metrology at present. It simply eases the measurement procedure and reduces the time to generate report/calibration certificate as well as in establishment of advanced techniques for measurement. Automation improves the measurement uncertainty as it eliminates the human error in measurement. An automation program has been developed for a High Frequency LCR Meter.Keywords

Induction hardening is a Localized heat treatment in which the Surface layer is hardened to a certain depth leaving the core of the work unhardened. Heating by high frequency current is accomplished by the thermal effect of the current induced in the workpiece being heated, which is placed in an alternating magnetic field. Present study is conducted to improve the quality by establishing the process parameters of induction hardening to get consistency in case depth. Parameters like quench bath temperature, quench concentration. Flow rate, Inductor-to-Inductor variation. Heating Time & power level was considered for experimentation. It was found that quench bath temperature, flow rate, quench concentration, do not have significant effect on the case depth. Only power level & heating time affect the case depth exponentially.- Fatigue Testing Procedure of 6 Cylinder Diesel Engine Crankshaft
