    摘要:

    引入加工面生成點概念，提出基于瞬時切削力的刀具變形計算和變形刀具移動掃描體的實體建模方法,，通過布爾運(yùn)算生成包含有幾何與物理誤差的仿真加工模型, 以圖形動態(tài)顯示仿真加工模型的生成過程,，并給出精確測量仿真加工模型的方法; 采用PARASOLID建模核心和OpenGL對上述算法完成系統(tǒng)實現(xiàn)。仿真和實際加工試驗結(jié)果表明,，最大仿真誤差為0.012mm,、最小仿真誤差為0.004mm，平均仿真誤差為

    Abstract:

    0.008mm,。By introducing the concept of surface generation points, an instantaneous force based tool deformation calculation method and the solid modeling method of deformed tool swept volume were proposed, and the solid model of machining simulation including geometry and physical errors were generated. The machining process was shown by computer graphics dynamically and the measurement method for solid model of machining simulation was also presented. The whole system was implemented by using OpenGL and PARASOLID modeling kernel. The result of machining simulations case study and the actual machining experiments indicate that the maximum and minimum simulation errors were 0.012mm and 0.004mm respectively, and the average error was 0.008mm. 
