Its level of development stands for the economic power, technical and scientific level, living standard and national defensive power of the country or area. While the capability of production in trade of manufacture mostly depends on the advanced producing equipment－machine tool .BRThis paper has carried out detailed analysis for the case cover processing technology of gear reducer that joins hole, the processing for its hole have put forward the train of thought of once pack folder, work position is processed , reach the precision requirement of product pattern .According to this train of thought , have designed the fouraxle first work drilling machine of bit alignment.BRThis modular machine tool is formed by pillar , pillar base , center base, Y、Z axle hydraulic slide unit, hydraulic station, head, cutting tool and control partial etc . The design of this paper for each part has carried out the detailed method that calculates and expounds and proves and has put forward the structure of optimization technology. The PLC control of adopting is steady and reliable. It has important meaning to raising the working efficiency and quality of case cover hole by the successful design of machine tool. After the design of machine tool is analysed, raise theamp。BR關鍵詞：制造業(yè)；減速器；四軸頭多工位同步鉆床；組合機床；PLC控制 p class=39。它的研制成功對提高箱蓋孔加工的工作效率和質(zhì)量具有重要的意義。本文對各部分的設計進行了詳細的計算和論證，并提出了優(yōu)化工藝結(jié)構(gòu)的方法。根據(jù)這一思路設計了四軸頭多工位同步鉆床。而制造業(yè)的生產(chǎn)能力主要取決于制造裝備——機床的先進程度。Tdz76439。Tdz76439。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。nbsp。Tdz76439。Tdz76439。結(jié)構(gòu)設計部分包括結(jié)構(gòu)選型、結(jié)構(gòu)布置、結(jié)構(gòu)計算、施工圖的繪制等，綜合運用天正建筑等軟件對計算數(shù)據(jù)進行了驗算和調(diào)整。底層另設有宿舍管理室。在本建筑設計中，充分利用建筑內(nèi)的空間，合理的房間布置，簡潔的結(jié)構(gòu)布置設計，充分利用了框架結(jié)構(gòu)的優(yōu)點。/p /pP/Pp 內(nèi)容簡介/p p 該樓位于北京市，5層，總面積為4000m2，采用的是框架結(jié)構(gòu)。/p br /（二）2002年各項經(jīng)濟指標完成情況br /（三）與2002年相對比，財務指標增減變動分析（提出問題）br /三、改變企業(yè)成本管理現(xiàn)狀的對策br /（一）改進企業(yè)成本管理br /改進企業(yè)成本管理的必要性br /企業(yè)成本管理的目標br /傳統(tǒng)成本管理已不適應XXX廠成本管理的需要br /（二）實施作業(yè)成本管理br /制造企業(yè)成本控制的實質(zhì)br /作業(yè)成本控制模型 br /實施作業(yè)成本管理br /（三）加強企業(yè)管理費用的預測與控制br /企業(yè)管理費用的預測br /企業(yè)管理費用的控制br /結(jié) 論 br /致 謝 br /參考文獻 br /附錄：外文資料 p class=39。 字br /摘要br /Abstractbr /一、中國加入WTO對現(xiàn)代的影響br /（一）對國家宏觀經(jīng)濟的影響br /（二）對我國工和機械行業(yè)的影響br /（三）如何面對WTO的挑戰(zhàn)br /二、XXX廠經(jīng)營概況br /（一）企業(yè)概況 p class=39。 Cost driverbr /br /目錄amp。amp。amp。 amp。Activityamp。 amp。amp。amp。 成本動因br /br /Abstractbr /Activity Based Costing, namely based on Activity cost puting method, mean and regard Activity as indirect expense return target of collecting, Through resource affirmation, measurement of reason, belong to and raise funds source expenses get Activity, Measure, belong to and collect through Activity affirmation of reason Activity cost get products or indirect expense that customer get on distribute the method and then.
