Small Automatic Processing Line Cnc System Design

AT the new condition of our country accede to WTO and external more deepen, it is importance develop numerical control technology and equip, advance manufacturing level and international contend ability. Advance production efficiency, debase produce cost, advance machining quality, celerity instead production, it is the base of machine manufacturing compete and develop, and also the sign of the technology lever.The fast development of NC machine tools based manufacturing technology towards high efficiency, flexibility and high speed, high efficiency and high precision, multi-tasking and networking. It greatiness advance production efficiency, and also flexible corresponding differ produce, shorten produce prepare time, as soon as possible the mew production expand market.Under the consideration of the need of our country equip making market, the need of our country for mental machining, based on the modern NC knowledge, analogue, digital knowledge, computer knowledge, network knowledge and auto-control theory. This paper proposes the design. Using many economy minitype machining center construct utility flexible automatism product line, realize production machining automatization dimensions.high precision.satisfy the need of high efficiency. The design of electric control systems used CNC (Comptuter Numerical Control),and used the CNC insede-store PLC (Programmalbe Logic Control).Then to finished process contrel peripheral equipment of entire machine and accessories cell, interface module include machine,otherwise control,trouble diaguose,network communications and also.The automatism product line,amalgamated machine,PLC cortrol,AC timing and sensor technology,belong to representative engine-electricity production,the center console finished entire product line control and operate.set up conditions show.measure date show,and across network date convection.This paper is divided into seven chapters.The first chaptersummarized the disgn's background and applications.The second chaper introduced knowledge aboud CNC and PLC.The trird chapter described the principium of CNC design,it is the paper's kernel part,the auto-tool change system and auto-tool break check system were solved.The forth chapter described the principium of automatism product line, it is also the paper's kernel part .The fifths chapter described the product line debug and the new problems that we meet at the debugging time.The last chapter summed up all design and pay attention to the new problems.It is high automatization.high efficiency.high quality and high precision of the automatism product line,the use results show it will have widely appliance foreground,it will make greatness economy advantage.The automatism product line is very less in our country,there is alack of self-help empolder,the developing succeed of this type preduct line can advance the manufacture machining level of our country,it will have widely market.
