More researchers have been worked to increase the quality of the machined composite materials. In this paper, a comparative experimental study of mechanical techniques over the laser techniques has been performed in the drilling process by using the carbon fiber reinforced polymer (CFRP). In order to identify the best process among the mechanical drilling (MD) and laser drilling (LD) technology various analysis methods like normality analysis, control chart analysis, and process capability analysis have been performed. Process capability index analysis for case study 1 and interval plot analysis for case study 2 have been employed to evaluate the best process comparatively. Experiments have been performed in a vertical machining center (VMC) and CO2 laser. The final results revealed that the MD process is the best technology for drilling CFRP. Therefore, this work has been important for small-scale industries.

Abstract


More researchers have been worked to increase the quality of the machined composite materials. In this paper, a comparative experimental study of mechanical techniques over the laser techniques has been performed in the drilling process by using the carbon fiber reinforced polymer (CFRP). In order to identify the best process among the mechanical drilling (MD) and laser drilling (LD) technology various analysis methods like normality analysis, control chart analysis, and process capability analysis have been performed. Process capability index analysis for case study 1 and interval plot analysis for case study 2 have been employed to evaluate the best process comparatively. Experiments have been performed in a vertical machining center (VMC) and CO2 laser. The final results revealed that the MD process is the best technology for drilling CFRP. Therefore, this work has been important for small-scale industries.
