Laser drilling parameter optimization for Ti6Al4v alloy

Abstract

Abstract The modern era fully deals with the laser drilling process for making holes in the hardest material for more precise holes. Here we have chosen a titanium alloy Ti6Al4v of 1\u202fmm thickness. The Taguchi method is used to optimize the process parameters. The process parameters we are considering laser power, laser speed, and frequency for Response hole Circularity. The S/N ratio deals with the influencing parameters which affect the hole diameter. The frequency and speed are the more influencing ones. The ANOVA makes the process more significant in responses. However, the quality and accuracy of the holes can be excellent, if the optimal Process parameter has been optimized by using the S/N ratio. Hole circularity increase with frequency and speed increases. ANOVA was found the most significant parameters of hole circularity.
