Technological process of laser milling using Q-switched mode is investigated. The results of laser influence (surface roughness, its chemical composition and thickness of the removed layer) are demonstrated to significantly depend on the processing regimes as well as on thermal and physical properties of the work piece. The quality of laser milling also depends on the amount of the liquid phase that occurs at laser heating and on the mechanisms of the material removal.
Keywords: laser technology, laser dimensional processing, laser milling, intractable materials.
