Abstract


Truss steel building known as the 21st century \Steel structure in the national economy, the construction of a wide range of applications in various industries , is a booming construction industry in China is both ancient and new industries . Steel construction , pipe Intersecting the most common phenomenon . Works to ensure good quality , you must first cutting a good pipe intersecting intersecting line and welding groove , the cutting process is a key link of an impact on the quality of the grid and steel structure . Tube intersecting line cutting , cutting machine torch cutting angle changing cut branch pipe cutting thickness also followed the change with . Existing CNC cutting machine is guaranteed cut the maximum cutting thickness of the branch pipe can be cut through the principle of setting the cutting speed , cutting efficiency . To this end, this paper possession intersection CNC cutting machine control system launched , through the establishment of the pipe intersecting intersecting lines , intersecting line of CNC cutting mathematical model interpolation and variable step size control algorithm , to achieve Axis CNC controlled cutting machine to improve CNC cutting efficiency . The main work of this paper are as follows: The first chapter is an introduction , CNC cutting machine processing status quo and development as well as open CNC system architecture , describes the background and main research content of this paper . The second chapter analyzes the movement and structure of the Axis CNC cutting machine , PMAC card - based CNC cutting machine control system built hard- and software components , do PMAC multi-axis motion controller card features and applications brief introduction. Chapter possession intersecting intersecting line cutting groove mathematical model and the intersecting line cutting motion control algorithm . The fourth chapter describes the cutting machine servo system tuning PID parameters based on PMAC card . Chapter introduced the modular design of the system control software and the development of the system prototype . Finally , the authors of the research content , and the prospect of the development of the CNC cutting machine .
