【摘要】：以深冷處理D2工具鋼為研究對象,建立其在線切割加工過程中的能量比、單位時間去除材料體積、工件加工表面粗糙度數(shù)值計算模型,運用MATLAB軟件進行分析,并用試驗驗證。仿真分析及試驗驗證的結(jié)果表明:隨著加工電流和脈沖寬度的增加,能量比不斷增加;隨著加工電流的增加,單位時間去除材料體積逐漸增加,而隨著脈沖寬度的增加,單位時間去除材料體積呈現(xiàn)逐漸減小的趨勢;隨著加工電流和脈沖寬度的增加,工件加工表面粗糙度呈現(xiàn)先減小后增加趨勢;單位時間去除材料體積、工件加工表面粗糙度的仿真計算值與試驗測量值最大相對誤差分別為4.76%、4.75%,相對誤差較小,驗證數(shù)值分析的正確性,為工具鋼線切割加工最佳工藝參數(shù)選擇及工藝優(yōu)化提供理論依據(jù)。
[Abstract]:Taking the cryogenic D2 tool steel as the research object, the numerical calculation model of energy ratio, material volume removal per unit time and workpiece surface roughness in the process of wire cutting is established. The model is analyzed by MATLAB software and verified by experiments.The results of simulation analysis and experimental verification show that the energy ratio increases with the increase of machining current and pulse width, the volume of material removed per unit time increases gradually with the increase of processing current, and with the increase of pulse width, the energy ratio increases with the increase of processing current and pulse width.With the increase of machining current and pulse width, the surface roughness of workpiece decreases first and then increases.The maximum relative error between the simulated and measured values of workpiece surface roughness is 4.76 and 4.75, respectively, and the relative error is small, which verifies the correctness of the numerical analysis.It provides a theoretical basis for the selection of optimum process parameters and process optimization for wire cutting of tool steel.
