摘要
本文介紹了離合齒輪的加工工藝設(shè)計過程及其專用夾具的設(shè)計過程。通過本設(shè)計進一步了解了機械加工工藝設(shè)計過程的一般方法和步驟。聯(lián)系生產(chǎn)現(xiàn)場實際條件進行工藝方案的比較選擇適當(dāng)方案；掌握根據(jù)生產(chǎn)的要求設(shè)計專用機床夾具的方法。
本文內(nèi)容包括：機械加工工藝的組成，工藝過程的作用，工藝規(guī)程的作用，工藝規(guī)程的設(shè)計原則，生產(chǎn)綱領(lǐng)的計算和生產(chǎn)類型的確定，毛坯的制造形式，制造工藝中基準(zhǔn)的選擇，零件的尺寸、形狀誤差和位置誤差的分析，機械加工工藝路線的確定，各個工序的加工余量、工序尺寸。尺寸公差的確定及某些刀具的幾何參數(shù)的選擇和常見的金屬切削機床的選用，機械加工各工序的切削深度、進給量、些小速度的確定，機械加工工時的計算，專用夾具設(shè)計的基本要求，專用設(shè)計的依據(jù)、夾具裝置的選擇、夾緊力的估算、定位誤差的分析、夾具的操作說明。本文介紹的各個工序都要保證使用功能要求、提高勞動生產(chǎn)率，保證加工質(zhì)量、降低勞動強度，注意勞動保護和環(huán)境保護，提高可靠性出發(fā)進行各個工序的工藝和夾具的比較和制定。為了更好的了解各國先進的工藝技術(shù)文本還選擇了兩篇相關(guān)的英文文獻進行了可供讀者參考
關(guān)鍵詞：機械加工；工藝；機械加工余量；工序；夾具；機床

Abstract
In this paper, the processing gear off the design process and its dedicated fixture design process. Through the design of a better understanging of the engine machining process of the gengral process design methods and steps. Contace production at the scene of the actual conditions of the programme compared select the apptopriate progrannes; master in accordance with he requirements of the production design for the machine tool fixture methods and in accordance with commercial interesrs of the programme compared with the technical and economic analysis.
This areicle includes: the composition of mechanical processing technology, the role of a point of order, the order of the design principles, the calculation of the Ptogramme of production and production types of identification, the rough form of manufacturing, manufacturing process in the choice of benchmarks, spare parts The size,shape and location of error of error, mechanical processing line of development, the variots processes machining allowance,process size, Tolerance and the determination of certain tools geometric parameters of common metal-cutting dpeed the identification, machining wotking hours, the fixture design gor the basic requirements, rhe basis for fixture design, the choice of fixture installation, the clamping force estimamates, positioning error the analysis, fixture instructions. This paper describes the various processes are guaranteed from the use of functional requirements, raising labor producticity, and ensure ptocessing qualitu, reduce labor intensity and attention to labor protection and environmental protection, to improve the reliability of the process and the process of comparison and the development of fixture. In order to better understand the countrides of advanced technology has also selected the two texts related to English literature afeference for readers.
Keywords: Engine machining ; process;machining allowance；processes; fixture; Machine
