【摘要】：為了改善高強度環(huán)槽鉚釘斷頸槽車削加工過程切槽刀具磨損嚴重的問題,對環(huán)槽車削加工工藝參數(shù)與刀具磨損速度的關系進行了研究。運用正交試驗法設計實驗,得到不同工藝參數(shù)下切槽車刀前刀面的磨損速度。經(jīng)過數(shù)據(jù)分析建立切槽車刀前刀面磨損速度預測數(shù)學理論模型,運用最小二乘法擬合實驗數(shù)據(jù),獲得切槽車刀前刀面磨損速度與工藝參數(shù)之間的關系�？紤]切削效率對加工過程的影響,運用遺傳算法尋求考慮切槽車刀前刀面磨損和加工效率綜合影響的全局最優(yōu)參數(shù)組合,為高強度環(huán)槽鉚釘斷頸槽車削加工提供了理論參考。
[Abstract]:In order to improve the serious problem of cutting tool wear in the turning process of high strength ring groove rivet with broken neck groove, the relationship between cutting process parameters and cutting tool wear speed was studied. The orthogonal test method is used to design the experiment, and the wear speed of the cutting tool face under different technological parameters is obtained. Through the data analysis, the mathematical model of predicting the wear velocity of the front cutter face of the slot car is established, and the experimental data are fitted by the least square method, and the relationship between the wear velocity of the front cutter face of the slot car cutter and the technological parameters is obtained. Considering the influence of cutting efficiency on the machining process, genetic algorithm is used to find the global optimal parameter combination which considers the comprehensive influence of cutting tool face wear and machining efficiency, which provides a theoretical reference for the turning of high strength ring-groove rivets with broken neck grooves.
