Study On The Software Of Automatic Cutting System (ACS) For New CNC Flame Cutting Machine

Numerical control flame automatic pipe-cutting machines are widely used in the cutting and welding industry of various pipe and sheet metal components,and they are pivotal equipments in producing ocean platform jacket components.As the requirements to the efficiency and accuracy of the metal structures cutting have become more and more strict,and the cutting style has become more and more complicated,the software system of the old pipe cutting machine can not meet the technical requirements.So after study on new imported flame automatic machine in China Petroleum Platform Manufacturing Company,the research falls to developing independent intelligent and automatic software control system,which gets rid of defeats of inconvenience and incompleteness of jacket joint intersecting curve models in software system enclosed with the imported machine.We also take use of the research results of intersecting lines and groove model that the Hydraulic Institute of Tianjin University have achieved for years.The research aims at equipping an intelligent and automatic software system which is easy to operate,with complete intersection model and information management database for the new Numerical control flame automatic pipe-cutting machines.The main achievements of this paper are:This paper adapts Modular design thought,and uses the VLISP program language to implement all function modules of the software system,including the generation module of parts information,judgment module of intersecting line type,computing module of bar geometric parameters and location parameters,computing module of intersection curve,data-processing module,designing module of engineering drawings and computing module of weight and centre of gravity.Mathematical model including opening round of the trough,board-pipe non-vertical intersection,cutting square hole,cutting hole,cutting crown curve and so on.Then integrates these with the intersecting curve model of pipe-pipe,board-pipe, cone-pipe and ring-pipe to establish the integrated Intersection curve math model base and develop the model in future.Through testing and application on the spot,the new system has increased the accuracy and reliability of jacket components cutting process.As such,the producing efficiency has been improved greatly.
