摘 要
這次的畢業(yè)設(shè)計(jì)的主要內(nèi)容是編制數(shù)控滾齒機(jī)傳動(dòng)箱體的粗精加工——編制數(shù)控加工工藝及部分部件所需的程序，主要為孔系的加工。
數(shù)控加工中心現(xiàn)今在許多重型機(jī)械廠的應(yīng)用比較廣泛，因其加工的零件可以很大，而且加工精度也同時(shí)能達(dá)到很好的精度，所以選用加工中心加工大型零件是很好的選擇。本篇主要涉及使用加工中心加工數(shù)控滾齒機(jī)傳動(dòng)箱體的面、孔系、螺紋、孔銷孔等等。此外，結(jié)合圖形對(duì)各個(gè)部件的加工列出加工工藝，程序及其相關(guān)的參數(shù)和刀具的選擇，完成對(duì)整個(gè)工件的加工過(guò)程。

關(guān)鍵詞：數(shù)控滾齒機(jī)傳動(dòng)箱體、數(shù)控程序、數(shù)控技術(shù)

Abstract
Design graduates this is the major content of the preparation of CNC machine transmission box of rough finished -- the establishment NC Arts and parts of the process, mainly holes processing. CNC Machining Center today drafted in many of the most widely used, because of the processing components can be great, and machining precision could also have reached a very good precision, are used for processing large parts processing center is a good choice. This mainly involves the use of CNC machining centers machine transmission box of noodles, holes, screw, etc.-pin hole. In addition, the combination of various components of graphics processing list processing, procedures and related parameters and tool choice, completion of the entire workpiece machining process.
Keywords : CNC machine transmission box, NC, NC technology
