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

Complex geometries and porous components are very difficult to manufacture using traditional methods. Powder metallurgy is a metal forming process that allows complex shapes to be easily formed without loss of material. Metal matrix composites are used for high thermal conductivity and high wear resistance. In Al-B4CP, the composition of boron carbide is changed by 5%, 10%, 15%, and 20%. Al-SiCp composites maintain similar weight fractions. The blended mixture is compacted and sintered to the required standard sample size. After heat treatment, samples are tested for wear rate using a pin-on-disc wear tester, which is analyzed with analysis software.
