| Abstract in different language: | Laser machining is one of the most widely used advanced machining processes used for creating new surfaces, structures, cavities and also complex electro-mechanical devices, usually with very small dimensions, by laser radiation. Optimal selection of process parameters is highly critical for successful material removal and high machine surface quality. In the paper the relation between process parameters and machined surface quality characteristics is experimentally studied applying the five axis highly dynamic laser precision machining centre Lasertec 80 Shape equiped with the pulsed ytterbium fibre laser (wave lenght 1064 nm, maximal average output power 100 W) and CNC system Siemens 840 D and commercionally pure titanium (Grade 2) as working material. The influence of the pulse frequency and energy, laser scanning speed and stepsize (spacing between adjacent passes) on the machined surface roughness is evaluated using Taguchi experimental design approach. The influence of process parameters on surface quality is investigated for two laser scanning strategies: hatching and crosshatching. The significant influence of the stepsize on the machined surface roughness was found. |
