Large-diameter hole CNC flame cutting machine

Have all the necessary documents interpolation data file (data area), servo control module based on the data file to determine its control actions, and document management modules other than the addition to the parameters of the display is also responsible for man-machine interface,[link widoczny dla zalogowanych], real-time control of the state refresh the display, key keyboard and remote control box, and the interpretation of the scheduling of the other two modules. Servo control module which is implemented by the interrupt service routine to ensure that its real-time Pi. Figure 7. 2.3 software features designed CNC flame cutting system is actually a track servo control system. Calculate the cut at the beginning of the node before the data and to interpolate the required data, and then to interpolate sub-control running track torch cut out to meet the requirements of the hole. Under the control of the software of the system has the following features: 1) adjusting the positioning function: in the processing of previous cutting machine and adjust the relative position of the workpiece. Including the proofreading function of zero, the system needs to know the torch and the relative position of the workpiece to establish the system coordinates. This is an important preparation before processing. 2) The servo function: the system can automatically be calculated and compensated data points to adjust the line to maintain the position of axis trajectory and consistent track surface. 3) The original track back function: this is essential for flame cutting, without cutting through the steel plate is random, it is difficult to judge. Found in the operator does not cut through steel, it can turn off the valve first, then press the \turn left \This process can be repeated anywhere in the cut any time. 4) accelerating or decelerating control: changes in the state machinery and equipment (such as acceleration, deceleration, stop, start) is easy to produce impact, to avoid or minimize the impact, the control system will automatically add a smooth, slow down. 5) adaptive variable functions: processing, cutting the thickness of the cutting point is changing, especially in the more obvious when the cutting groove. When cutting the parameters given, the system can calculate the thickness of the cutting point cut and in accordance with \for the system of reference) that cutting speed, the system will be based on various points of the \6) Compensation: Compensation is to ensure that an important measure for cutting accuracy. The system implements a one-time compensation of hysteresis error (the reverse movement occurs when compensation). Groove cut in the realization of the mouth of the slope and contour error generated slotted compensation. 7) characters, graphics display: This is an important part of human-computer interaction. The system provides a full Chinese menu-style interface, the interface shows the operator cutting the information needs of the system, such as speed, rotation, lifting distance. Cool

The remote control box control: CNC system for easy operation with a remote control device. For fine-tuning, jog and real-time on-site intervention operation. The intervention consisted of an artificial running track speed adjustment and panning up and down. There are many factors when flame cutting can not be predicted, in order to keep the root and other technical indicators to ensure,[link widoczny dla zalogowanych], if necessary, minor adjustments can be intervention. 9) parameter configuration functions: processing requires a lot of parameters, the parameters of a workpiece but also the parameters of the system. This function is used to modify the parameters of the system to adapt to the actual situation. 3 Conclusion of the research projects to solve three-dimensional projection of cutting large diameter holes of technical problems,[link widoczny dla zalogowanych], large-diameter hole made CNC flame cutting machine has been successfully applied to the construction of ships, high-quality and efficient completion of all the key cutting task. The technology to fill the gap, and has passed the technical appraisal of Heilongjiang Province. This equipment can be used in shipbuilding, marine engineering structure of large pipe, pressure vessel manufacturing, petroleum chemical equipment, metallurgical, vehicles and bridges, etc., have a good application prospect.
