摘要(中)

本文首先驗證了Deform-3D有限元素法軟體應用於模擬M1.2擠壓絲攻加工之內螺紋成形的妥適性。選取下孔徑、轉速、定剪摩擦因子三個製程參數為品質因子，探討對攻絲過程中的內螺紋飽牙率與絲攻的最大扭矩兩個品質特性的影響。實驗設計採用面心式中央合成法設計共18組的實驗點。使用Minitab統計軟體對模擬的結果進行了變異數分析，進而建立最大扭矩與飽牙率的迴歸模型，並透過最佳化設計找出在限制飽牙率的條件下，最小化最大扭矩值的最佳製程參數水準值。為了驗證迴歸模型的準確性，使用了Deform-3D有限元素模擬的結果對迴歸模型進行檢驗，結果顯示最大扭矩與飽牙率的迴歸模型具有良好的預測能力。

摘要(英)

In the present study, the validity of internal thread forming in the M1.2 forming tap process based on Deform-3D Finite Element Method(FEM) software was first verified. the three process parameters of bottom hole diameter, rotational speed and constant shear friction were identified control variables, and investigates the influence of the two responses of the thread fill rate and the maximum torque of the tap during the tapping process. and face-centered Central Composite Design (CCD) were used for the experimental design with 18 experimental runs. Analysis of variance(ANOVA) based on the simulation results established the regression model of maximum torque and thread fill rate by using Minitab software, and find out the optimal levels of process parameters that minimizes the maximum torque within a constrained region of thread fill rate by optimization design. in order to verify the accuracy of the regression model, the regression model was validated using the results of Deform-3D finite element simulation, the results showed that the regression model of the maximum torque and the thread fill rate had good predictive ability.
