【摘 要】：
撥叉行業(yè)是我們通用機(jī)械重要分支，無論是在工業(yè)還農(nóng)業(yè)中，只要有流體管道的地方,閥門的作用都是巨大的，而隨著時(shí)代的發(fā)展，撥叉的類型也發(fā)展的越來越全面，制造撥叉的技術(shù)也越來越先進(jìn)。本文一例撥叉零件數(shù)控車床加工的程序編制與步驟，加工工藝的選擇問題進(jìn)行探討。進(jìn)行整套的工藝分析與計(jì)算，按工藝程序卡進(jìn)行編程與加工。
【關(guān)鍵詞】：撥叉 數(shù)控加工 工藝 數(shù)控銑床

[ Abstract ]:
Dials forks the profession is our general machinery important branch,regardless of is in the industry also agriculture, so long as has thefluid pipeline the place, the valve function all is huge, but alongwith the time development, dials the type which forks also to developmore and more comprehensively, the manufacture dials the technologywhich forks more and more to be also advanced. A this article exampledials forks the programming and the step which the componentsnumerical control lathe processes, the processing craft choicequestion carries on the discussion. Carries on the entire wrap thecraft analysis and the computation, carries on the programming and theprocessing according to the craft procedure card5
