Graduation practice examination questions is that the dyadic vacuum of period plates with film machine design , come from Jin Zhou prospering in business blessing vacuum equipment Ltd."The dyadic vacuum of period plates with film machine design " designing that machinery , liquid move mainly , the pneumatic , PLC control , solid modeling and emulation etc. is similar to content. Design passing above-mentioned examination questions, the student can have machinery design in hand , PLC controls , the fundamental process that liquid relevance content such as move and pneumatic designs reaches to the software programming and simulated Pro/e model study about, train knowledge and practice applying basic theory synthetically an ability , be that study about and job with the future lay down fine basis. That this is similar to a rig is to gather machinery , liquid moves , the pneumatic , the electricity let representative machine , electricity , liquid , gas equipment for an integral whole trickle out. The mechanical part design needs the function and service conditions having every component in hand sufficiently, by the fact that the various arithmetic reaches optimum design call for; Liquid moves a part designing the sufficient relevance knowledge .know about that need designs to the various hydraulic pressure component function and circuit , can combine with PLC under the control of each other and, the expected effect making use of soft hardware to design realization, makes use of Pro/e to carry out model on the machine tool , can carry out development simulating and. Hydraulic drive and the electricity charge soft hardware design and solid modeling by the fact that originally, graduation practice may have special use machine tool machinery physical design in hand , machinery content such as motion and driving force part design designing that,simulate and so on first turn off knowledge, cultivate out student apply basic theory knowledge solve actual apply problem ability.
