35、工廠，由于生產(chǎn)組織嚴密，分工細致，要求工藝規(guī)程比較詳細，才能便于組織和指揮生產(chǎn)。對于單件小批生產(chǎn)的工廠，工藝規(guī)程可以簡單些。但無論生產(chǎn)規(guī)模大小，都必須有工藝規(guī)程，否則生產(chǎn)調(diào)度、技術(shù)準備、關(guān)鍵技術(shù)研究、器材配置等都無法安排，生產(chǎn)將陷入混亂。同時，工藝規(guī)程也是處理生產(chǎn)問題的依據(jù)，如產(chǎn)品質(zhì)量問題，可按工藝規(guī)程來明確各生產(chǎn)單位的責任。按照工藝規(guī)程進行生產(chǎn)，便于保證產(chǎn)品質(zhì)量、獲得較高的生產(chǎn)效率和經(jīng)濟效益。 2 工藝規(guī)程是生產(chǎn)組織和管理工作的基本依據(jù)。首先，有了工藝規(guī)程，在新產(chǎn)品投入生產(chǎn)之前，就可以進行有關(guān)生產(chǎn)前的技術(shù)準備工作。例如為零件的加工準備機床，設計專用的工、夾、量具等。其次，工廠的設計和調(diào)度部門

36、根據(jù)工藝規(guī)程，安排各零件的投料時間和數(shù)量，調(diào)整設備負荷，各工作地按工時定額有節(jié)奏地進行生產(chǎn)等，使整個企業(yè)的各科室、車間、工段和工作地緊密配合，保證均衡地完成生產(chǎn)計劃。 3 工藝規(guī)程是新建或改（擴）建工廠或車間的基本資料。在新建或改（擴）建工廠或車間時，只有依據(jù)工藝規(guī)程才能確定生產(chǎn)所需要的機床和其它設備的種類、數(shù)量和規(guī)格；車間的面積；機床的布局；生產(chǎn)工人的工種、技術(shù)等級及數(shù)量；輔助部門的安排。 但是，工藝規(guī)程并不是固定不變的，它是生產(chǎn)工人和技術(shù)人員在生產(chǎn)過程中的實踐的總結(jié)，它可以根據(jù)生產(chǎn)實際情況進行修改，使其不斷改進和完善，但必須有嚴格的審批手續(xù)。 二、工藝規(guī)程制訂的原則工藝規(guī)程制定的原則是優(yōu)質(zhì)、高產(chǎn)、低成本，即在保證產(chǎn)品質(zhì)量的前提下，爭取最好的經(jīng)濟效益。在制訂工藝規(guī)程時應注意下列問題： 1 技術(shù)上的先進性在制訂工藝規(guī)程時，要了解國內(nèi)外本行業(yè)的工藝技術(shù)的發(fā)展水平，通過必要的工藝試驗，積極采用先進的工藝和工藝裝備。 2 經(jīng)濟上的合理性在一定的生產(chǎn)條件下，可能會出現(xiàn)幾種能保證零件技術(shù)要求的工藝方案，此時應通過核算或相互對比，選擇經(jīng)濟上最合理的方案，使產(chǎn)品的能源、材料消耗和生產(chǎn)成本最低。 3 有良好的勞動條件在制訂工藝規(guī)程時，要注意保證工人操作時有良好而安全的勞動條件。因此，在工藝方案上要注意采用機械化或自動化措施，以減輕工共繁雜的體力勞動。 三、制訂工藝
