Abstract
This paper presents experimental investigation into the influence of machining parameters of Ytterbium fiber laser during machining of Al/5 wt%Al2O3-MMC. The response surface methodology (RSM) is used to achieve optimum responses i.e. minimum tapering and maximum material removal rate. A comprehensive mathematical model for correlating the interactive and second-order influences of Ytterbium fiber laser machining parameters such as laser power, modulation frequency, gas pressure, wait time, pulse width on metal removal rate and tapering phenomena has been developed for achieving controlled over fiber laser machining process. Test results reveal that the MRR is high at 15 bar gas pressure and 0.1s wait time. MRR is less at moderate gas pressure and moderate wait time. The gas pressure and pulse width both have great effect on taper. At low gas pressure i.e. 15 bar and low pulse width i.e.75% of duty cycle the taper is minimum.
