【摘要】：隨著科學(xué)技術(shù)的發(fā)展，制造業(yè)客戶需求產(chǎn)品向多品種、變批量方向發(fā)展，產(chǎn)品結(jié)構(gòu)趨于復(fù)雜化。而目前數(shù)字化制造車間主要以單件小批量的生產(chǎn)組織模式為主，對市場響應(yīng)力差，車間信息控制系統(tǒng)薄弱，信息交互困難，不能完成多品種、變批量的生產(chǎn)需求。為了改變數(shù)字化制造車間現(xiàn)狀，基于DNC網(wǎng)絡(luò)搭建了可重構(gòu)的開放式信息控制平臺(tái)，應(yīng)用可重構(gòu)制造技術(shù)，對車間生產(chǎn)零件進(jìn)行合理的工藝流程規(guī)劃，，解決數(shù)控加工設(shè)備加工能力不足等問題。 本文首先對生產(chǎn)制造模式的發(fā)展進(jìn)行了分析，闡述了可重構(gòu)制造系統(tǒng)的理論基礎(chǔ)及其發(fā)展過程，介紹了可重構(gòu)制造系統(tǒng)的特點(diǎn)及組成，論述了可重構(gòu)制造系統(tǒng)在先進(jìn)制造模式中的競爭優(yōu)勢和關(guān)鍵技術(shù)。 其次，進(jìn)行了數(shù)字化制造車間制造流程規(guī)劃的研究。介紹了零件族的劃分方法，并對零件族加工信息描述方法進(jìn)行闡述，分析了數(shù)字化制造車間的組織運(yùn)行情況，提出了數(shù)字化制造車間對生產(chǎn)流程重構(gòu)、信息控制重構(gòu)及物流系統(tǒng)重構(gòu)的需求。 最后，在工藝規(guī)劃需求下，進(jìn)行了復(fù)合機(jī)床的改造，實(shí)現(xiàn)加工工件一次性裝夾定位，完成工件由毛胚到成品的加工，提高了加工精度及生產(chǎn)效率，縮短生產(chǎn)周期，增強(qiáng)了車間數(shù)控設(shè)備的可重構(gòu)性。應(yīng)用ANSYS對鉆銑工裝主要零部件進(jìn)行動(dòng)靜力學(xué)有限元分析，驗(yàn)證箱體及鉆銑主軸的動(dòng)靜力學(xué)特性。分析了數(shù)字化制造車間對可重構(gòu)信息控制系統(tǒng)的需求，構(gòu)建了基于DNC的模塊化可重構(gòu)信息控制平臺(tái)。
[Abstract]:With the development of science and technology, manufacturing customer demand products to a variety of varieties, changing the direction of development, product structure tends to become more complicated. But at present, the digital manufacturing workshop is mainly single-piece small batch production organization mode. Poor response to the market, weak workshop information control system, difficult information exchange, can not meet the multi-species, variable batch production requirements. In order to change the status quo of digital manufacturing workshop. Based on DNC network, a reconfigurable open information control platform is built, and the reasonable process flow planning of workshop parts is carried out by using reconfigurable manufacturing technology. Solve the problem of insufficient machining capacity of NC machining equipment. In this paper, the development of manufacturing mode is analyzed, the theoretical basis and development process of reconfigurable manufacturing system are expounded, and the characteristics and composition of reconfigurable manufacturing system are introduced. The competitive advantage and key technology of reconfigurable manufacturing system in advanced manufacturing mode are discussed. Secondly, the manufacturing process planning of digital manufacturing workshop is studied. The method of dividing parts family is introduced, and the description method of part family processing information is expounded. This paper analyzes the organization and operation of the digital manufacturing workshop, and puts forward the requirements of the digital manufacturing workshop for the reconfiguration of the production process, the reconfiguration of information control and the reconfiguration of the logistics system. Finally, under the demand of process planning, the composite machine tool is reformed to realize the one-off clamping positioning of the machining workpiece, and to complete the processing of the workpiece from the wool embryo to the finished product, which improves the machining accuracy and production efficiency. The production cycle is shortened and the reconfiguration of numerical control equipment in workshop is enhanced. The dynamic and dynamic finite element analysis of the main parts of drilling and milling is carried out by using ANSYS. The dynamic and dynamic characteristics of the box and the spindle are verified. The requirements of the digital manufacturing workshop for the reconfigurable information control system are analyzed, and the modular reconfigurable information control platform based on DNC is constructed.
