碩士 === 國立虎尾科技大學 === 自動化工程研究所 === 103 === The laser cutting has proven to be the quality cutting process for almost any category of materials with few limitations. In paper, a high performance CNC laser cutting machine tool based on Design Chain Operations Reference (DCOR) Model is developed, and the discussion of components of CNC laser cutting machine tool and key points of design process is emphasized in specially. The multiple quality characteristics may be improved by controlling the process parameters at high level. Performance of multi-hole cutting of metal sheet is studied and several key parameters are given by changing assistant gas and process parameters. As a result, the experimental results show that high cutting quality can be obtained when argon is used as assistant gas, and oxygen is on the contrary. Also, in a certain range, improving laser power and cutting speed can help in decreasing laser cutting gap, reduction heat affected area, and achieving better cutting quality.
