The present work is on the spot drilling of black acrylic (PMMA) using a Diode laser of wavelength 809.40 nm. The design of experimental layouts for drilling has been done using the Taguchi's method. After drilling, the hole taper and the heat-affected-zone (HAZ) of the drilled holes have been measured. The influence of the experimentally controllable… (More)
