Abstract(s)
Laser beam machining is a non-traditional subtractive manufacturing process, a form of
machining, in which a laser is directed towards the work piece for machining. This process uses
thermal energy to remove material from metallic or non-metallic surfaces. The laser is focused
onto the surface to be worked and the thermal energy of the laser is transferred to the surface,
heating and melting or vaporizing the material. Laser beam machining is best suited for brittle
materials with low conductivity, but can be used on most materials. The role of the technical
equipment in laser milling is to perform a controllable action of the laser radiation on the
material to be treated. The laser is the main unit of the equipment and it is characteristics
determine to great extent the qualitative and quantitative parameters of the technological
treatments.
In this work, I had to study the laser milling process parameter selection for process
planning operations from start to finish. It was important to have an understanding about laser
milling and laser processing parameters for different materials. As a result from the laser milling,
the surface finish will have different surface properties such as, surface hardness, surface
roughness, friction and tribology etc.. During the process, I gained knowledge about the
historical and conceptual framework of laser milling, the different parameters of a laser milling
and how the laser milling parameters influence the surface properties of the machined parts.
