要機械制造業(yè)是一個國家技術(shù)進步和社會發(fā)展的支柱產(chǎn)業(yè)之一，無論是傳統(tǒng)產(chǎn)業(yè)，還是新興產(chǎn)業(yè)，都離不開各式各樣的機械裝備。而加快產(chǎn)品上市的時間，提高質(zhì)量，降低成本，加強服務(wù)是制造業(yè)追求的永恒主題。此次研究的主要內(nèi)容在于如何使加工工序簡單化、降低加工難度，從而達到提高產(chǎn)品加工效率，加快產(chǎn)品上市時間的目的。 And the research design for the fixture of first road processes (mill the interface), The main content of the study is how to simplify the processes, reduce processing difficulty, and thus achieve greater processing efficiency, speed up product listed time. Toward manufacturing pursued the theme over!Keywords: Trunk One surface and two holes Fixture Travel chart第 1 章 緒 論機械加工工藝規(guī)程必須保證零件的加工質(zhì)量，達到設(shè)計圖紙規(guī)定的各項技術(shù)要求，同時還應(yīng)該具有較高的生產(chǎn)率和經(jīng)濟性。 題目來源及選題的意義和目的題目來自于 BJ13
