Abstract
The customer demands on micro component usages have been increased in past some of the decades. So, the development is necessary to achieve desired smaller shape and size of components with high accuracy. In this work, blind-hollow cylindrical micro-hole fabrications of various diameter (0.5 x 0.7 mm, 1 x 1.4 mm and 2 x 2.8 mm) on Titanium grade (Ti6Al4V) were processed by Nd:YAG laser machine. The design of experiment, Analysis of Variance (ANOVA) techniques and effect of process parameters has been implemented to assess performance. The performance characteristics of the blind-hollow cylindrical micro-hole fabrication were evaluated through circularity and Feret’s diameter. The laser tuning parameter such as current, pulse frequency and air pressure were considered as input laser parameters.
Keywords: Circularity, Cylindrical micro-hole, Feret’s diameter, Heat affected zone, Image processing.
