Abstract

Laser beam micro-milling (LBMM) on titanium alloy (TA), nickel alloy (NA) and aluminum alloy (AA) has been performed under dry atmospheric conditions. Five different sizes of micro-channels were produced in each of the said material. The micro-channel sizes include 100x50 µm, 200x100 µm, 400x200 µm, 800x400 µm, and 1000x500 µm. A full factorial response surface methodology (RSM) based face centered central composite design (FCCCD) was utilized to produce every size of micro-channel in every material. In this chapter the actual machining results, parametric effects on process performance measures, microstructures and micro-hardness profiles are discussed.
