【摘要】：機(jī)床加工仿真不僅能夠清楚地看到虛擬加工過程,同時還可以發(fā)現(xiàn)機(jī)床運(yùn)行中的問題,對指導(dǎo)實際加工具有重要意義。本文通過基于VERICUT的蝸桿砂輪修整加工仿真的研究,主要從以下幾個方面進(jìn)行了研究:1首先簡要的介紹了齒輪磨齒機(jī)床的發(fā)展現(xiàn)狀,根據(jù)本次試驗所采用的試驗設(shè)備,詳細(xì)的介紹了YK7250數(shù)控磨齒機(jī)的機(jī)床結(jié)構(gòu)及特點。也指出了蝸桿砂輪磨齒中存在的一些問題,針對以上問題設(shè)計了三種蝸桿砂輪的修整方法,提出了預(yù)修整和精修整相結(jié)合的修整方案,最終選擇了外圓帶圓弧的金剛滾輪的修整方法。2其次介紹了數(shù)控加工仿真軟件VERICUT,然后根據(jù)加工仿真的要求,完成了在三維軟件Pro/E下建立的數(shù)控修整模型,并將修整模型導(dǎo)入到VERICUT中,在VERICUT系統(tǒng)下完成了虛擬機(jī)床的搭建,完成了修整機(jī)床的數(shù)控系統(tǒng)的設(shè)定,添加了NUM1060m.ctl數(shù)控系統(tǒng),并簡單的介紹了數(shù)控程序的運(yùn)行機(jī)制,最終完成了虛擬機(jī)床的搭建工作。3最后介紹了仿真所用的NUM數(shù)控系統(tǒng)以及該數(shù)控系統(tǒng)的編程方法,講述了仿真加工中金剛滾輪的運(yùn)動軌跡,并且計算出了蝸桿砂輪廓形對應(yīng)在刀具接觸點的等距曲線,完成了數(shù)控程序的編制,并進(jìn)行仿真加工和仿真加工過程的碰撞檢測,驗證我們所搭建的加工仿真系統(tǒng)的正確性。通過在VERICUT下的加工仿真,我們不僅清楚地看到了修整過程,而且還發(fā)現(xiàn)了加工過程中的錯誤并進(jìn)行了修改,最后在YK7250磨齒機(jī)上進(jìn)行了蝸桿砂輪的修整試驗,驗證修整方案的正確性和合理性。
[Abstract]:Machine tool machining simulation not only can clearly see the virtual machining process, but also can find the problems in the machine tool operation, which is of great significance to guide the actual machining. Through the research of worm grinding wheel dressing simulation based on VERICUT, this paper mainly studies the following aspects: 1. Firstly, the development status of gear grinding machine is briefly introduced, and according to the test equipment used in this experiment, The structure and characteristics of YK7250 CNC grinding machine are introduced in detail. This paper also points out some problems existing in grinding teeth of worm grinding wheel, designs three dressing methods of worm grinding wheel for the above problems, and puts forward a dressing scheme combining pre-dressing and fine dressing. Finally, the dressing method of the outer circle roller with circular arc is selected. Secondly, the NC machining simulation software VERICUT, is introduced. According to the requirements of the machining simulation, the NC dressing model established under the three-dimensional software Pro/E is completed. The dressing model is introduced into VERICUT, the virtual machine tool is built in VERICUT system, the NC system is set up, the NUM1060m.ctl numerical control system is added, and the running mechanism of NC program is introduced simply. Finally, the construction of the virtual machine tool is finished. Finally, the NUM numerical control system used in the simulation and the programming method of the system are introduced, and the motion track of the diamond roller in the simulation machining is described. The isometric curve of the worm wheel profile corresponding to the tool contact point is calculated, the NC program is compiled, and the simulation machining and the collision detection of the simulation machining process are carried out to verify the correctness of the machining simulation system built by us. Through the machining simulation under VERICUT, we not only see the dressing process clearly, but also find the error in the process and modify it. Finally, the dressing test of the worm grinding wheel is carried out on the YK7250 grinder. Verify the correctness and reasonableness of the dressing scheme.
