碩士 === 國立勤益科技大學 === 機械工程系 === 103 === Ocoing to the rapid development on new type industry,emerging industries with these materials are not fully fitted the goal,The development of key component is a continuous work .Recently the pure tungsten (Tungsten) material is a typical success example ,because it perfroms with high purity , high performance and superior alloys ,Tungsten is a dominant material for developing key component.In this thesis,the pure tungsten is cutting ,With CNC lathe construction method which is combined with the plasma-assisted processing technology (Plasma Assisted Machining) The destination is to find the optimsl mochining parameter. Firstly a conventional machining is constdered with plasma-enhanced processing technology,Experimental results show that the plasma -assisted machining reduces the cutting face and tool wear effectively,Secondly the destination is to find the signifieant factor whieh is decided wioh cutting force,tool wear and surface roughness, Notify that the variable factors are current (A),feed rate (F),cutting depth (Dp), speed (N), Minitab software is adopted to filter the test plan , By using the screening optimization experiment ,the optimized processing parameter can be decided with the regression analysis,With those sndysis the plasma-assisted processing technology (Plasma Assisted Machining) can be used in the cutting material of pure tungsten succesfully.
