| Abstract: | In order to cultivate students’ ability to identify, analyze and solve "Complex engineering problems", this paper analyzes the existing problems in the experiment of "Mechanical manufacturing technology basis" and "Tolerance and technical measurement", and designs a comprehensive cutting experiment. The experimental contents include determining the cutting parameter optimization model based on machining quality, efficiency and cost, setting up the cutting parameters and their levels according to the mechanical properties of new materials, designing the orthogonal experiment scheme according to Taguchi method, and adopting the virtual simulation experimental platform to master the use method of the experimental instrument and the construction method of the experimental platform. The cutting experiment is carried out, the sensitivity analysis of cutting parameters is conducted by using the tool software, the empirical formula is established, and the optimal cutting parameters are predicted. |
