【正文】 畢 業(yè) 設 計 說 明 書GRADUATE DESIGN設計題目：軸套類零件數(shù)控加工工藝及編程設計摘 要車削加工是在車床上利用工件相對于刀具旋轉(zhuǎn)對工件進行切削加工的方法。車削加工的切削能主要由工件而不是刀具提供。車削是最基本、最常見的切削加工方法，在生產(chǎn)中占有十分重要的地位。車削適于加工回轉(zhuǎn)表面，大部分具有回轉(zhuǎn)表面的工件都可以用車削方法加工，如內(nèi)外圓柱面、內(nèi)外圓錐面、端面、溝槽、螺紋和回轉(zhuǎn)成形面等，所用刀具主要是車刀。本文主要論述了軸套類零件加工工藝及設計編程，通過 UG 畫出零件圖及編寫程序，利用數(shù)控車床軟件仿真避免次品的產(chǎn)生和材料浪費，對零件進行工藝分析，通過 CKA6150 機床進行加工實體，很好的利用仿真軟件與機床的有機結(jié)合，加工出合格產(chǎn)品。此外本文還介紹了刀具的選擇和運用以及在加工過程中的注意事項等，分析了如何根據(jù)零件的幾何形狀特點設計加工工藝和操作步驟，以及操作過程中的相關(guān)參數(shù)選擇。實踐證明，在數(shù)控加工中，根據(jù)零件的不同部位的技術(shù)要求，合理安排不同的加工工藝，設置合理的加工參數(shù)，選擇合理的加工道具，不僅可以提高加工效率，保證質(zhì)量，而且還減少工具損耗。關(guān)鍵詞 車削加工 零件的工藝分析 編寫程序AbstractTurning the workpiece in a lathe using method of tool rotation relative to the workpiece cutting. Cutting machining is mainly posed of workpiece instead of cutting tools available. Turning is the most basic machining method, the most mon, occupies a very important position in the production. Turning for processing rotary workpiece surface, most has the rotation surface can be processed with the method of turning, such as the external cylindrical surface, conical surface, and face, groove, thread and rotary forming surface, the tool is mainly used tools.This paper mainly discusses the sleeve parts machining process and program design, through the UG to draw the parts diagram and program, using the numerical control lathe simulation software to avoid the defective products and material waste, the process analysis to parts, processing entity through the wide number 980 machine tool, the anic bination of simulation software and the machine to good use, processing qualified product.In addition, this paper also introduces the selection and use of tools and in the process of attention, analyzes how to according to the part geometry characteristics of the design process and steps, select the relevant parameters and operating process. Practice has proved, in NC machining parts, according to the requirements of the different parts of the technology, reasonable arrangement of different machining process, setting processing parameters reasonably, choose the reasonable processing tools, not only can improve the processing efficiency, ensure the quality, but also reduce the tool wear.Key Words: Turning Parts of the process analysis Write a program 目 錄摘 要 .............................................................................................................................IABSTRACT.......................................................................................................................II第 1章 緒 論 ................................................................................................................1第 2章 數(shù)控機床的概念 ..............................................................................................2 數(shù)控機床的概念 .................................................................................................................2 機床本身技術(shù)參數(shù) .....................................................................................................2 數(shù)控系統(tǒng) ......................................................................................................................2 數(shù)控加工的概念 ................................................................................................................3 數(shù)控機床的分類 ................................................................................................................3 按加工工藝方法分類 ...............................................................................................3 按控制運動軌跡分類 ...............................................................................................4 按驅(qū)動裝置的特點分類 ...........................................................................................4 數(shù)控車削加工工藝 ............................................................................................................5 合理選擇切削用量 ....................................................................................................5 夾具安裝要點 .............................................................................................................6 數(shù)控車床加工程序編程 ........................................................................................6 數(shù)控車床的組成和工作原理 ..........................................................................................7 車床主體 ......................................................................................................................7 數(shù)控裝置和伺服系統(tǒng) ...............................................................................................7 數(shù)控車床安全操作規(guī)程 ...................................................................................................7 數(shù)控車床坐標系的確定 ...................................................................................................8 運動方向確定 .....................................................................................................................9第 3章 套筒類零件的結(jié)構(gòu)特點及工藝分析 ............................................................10 軸承套加工工藝 ...............................................................................................................10 軸承套技術(shù)條件和工程分析 ................................................................
