Design of Virtual Experiment Teaching on Five-axis CNC Machi-
ning by Combining Modern Tools//DING Shuang, WU Weiwei, DAI Min, WEI Xinlong
Abstract In order to improve the engineering level and innovation ability of college students, construction of new engineering must be accelerated. The virtual machining experiment of five-axis CNC
machine tool based on the actual manufacturing process was designed
and practiced by combining modern mathematics tools MATLAB, engineering CAD/CAM software UG and simulation software VERI-
CUT. Virtual experiment can enhance perceptual cognition, promote free exploration and develop innovative thinking. Mathematics, information, engineering and other professional knowledge is inclu-ded in the teaching design and practice. Learning motivation of stu-
dents in various subjects is stimulated and teaching effect of CNC
technical course is improved by threading the knowledge of text-books together and constructing the learning ecological chain. The students can deeply understand the beneficial role and status of the studied knowledge. Virtual experiments can reduce costs, ensure safety, and effectively solve the practical problems of shortage of five-axis CNC equipment in universities.
Key words numerical control technology; five-axis CNC machine; virtual experiment; modern tools; MATLAB; UG; VERICUT

數控技術是一門包含機械設計及制造技術、機床技術、計算機技術、信息技術的機械專業基礎課程,對實踐教學環節要求很高。為確保實驗教學質量,必須改革實驗教學技術與手段,利用好多種現代信息工具,推進虛擬實驗教學應用[1-3]。針對數控技術課程虛擬實驗教學,劉旭波等人[4]
基于UG和浙大辰光數控虛擬加工軟件設計了三軸銑削加工虛擬教學實驗;李建廣等人[5]研究了基于虛擬仿真的數控加工技術實踐考評方法;蔡衛國[6]介紹了大連海洋大學機械工程虛擬實驗教學中的典型案例,利用CAXA軟件進行鼠標三軸數控加工的虛擬仿真教學。
