【摘要】：針對圓盤銑刀超聲切削過程中出現(xiàn)易碎及抱死等問題展開分析,提出一種用于Nomex蜂窩復(fù)合材料超聲切削加工的新型鋸齒圓盤銑刀。為了保證新型刀具滿足生產(chǎn)使用要求,對新型鋸齒圓盤銑刀展開分析,推導(dǎo)建立了鋸齒圓盤銑刀的動力學(xué)模型;應(yīng)用有限元軟件ABAQUS對鋸齒圓盤銑刀進(jìn)行模態(tài)分析,驗證了鋸齒圓盤銑刀結(jié)構(gòu)設(shè)計的合理性,為刀具的進(jìn)一步發(fā)展研究提供參數(shù)支持。結(jié)果表明:鋸齒圓盤銑刀第十二階振型理想,振動穩(wěn)定,振幅分布有規(guī)律,楔角θ=12°為鋸齒圓盤銑刀結(jié)構(gòu)的最優(yōu)選擇,符合超聲切削加工對刀具的要求。
[Abstract]:Based on the analysis of the problems of breakage and locking in ultrasonic cutting process of disc milling cutter, a new type of saw tooth disc milling cutter for ultrasonic machining of Nomex honeycomb composite material is proposed. In order to ensure that the new cutting tool can meet the requirements of production, the dynamic model of the new type saw tooth disc milling cutter is deduced and established, and the modal analysis of the saw tooth disc milling cutter is carried out by using finite element software Abaqus. The rationality of the structural design of the saw tooth disc milling cutter is verified, which provides parameter support for the further development of the cutter. The results show that the twelfth order vibration of sawtooth disc milling cutter is ideal, the vibration is stable, the amplitude distribution is regular, and the wedge-angle 胃 ~ (12 擄) is the best choice for the structure of the saw tooth disc milling cutter, which meets the requirements of ultrasonic cutting for the cutting tool.
