| Summary: | 碩士 === 國立成功大學 === 機械工程學系碩博士班 === 101 === This study investigated the effect of different processing conditions on the laser machining material removal process. First, laser added to improve the Machinability in Laser-assisted milling experiments to explore the influence of laser-assisted milling on the processing stability and compared with the relationship of material removal rate without laser-assisted machining. According to cutting coefficients experiments, the tangential cutting coefficients decreased significantly with laser assisted milling, and the results of milling stability experiments found that using laser assisted most effective way to increased critical depth of cut, thus the case had a better material removal rate in same radial depth of cut and feed processing. Then laser machining experiments with different laser parameters processed material surface, to observe the surface morphology and to explore the relationship of laser processing parameters on material removal rate. Taguchi experiment shows that pulses feed rate effect depth and width of groove most, pulse frequency effect least, and peak power between them. The maximum of material removal rate occurs at peak power, pulse feed rate and pulse frequency is high.
