Abstract

The system was developed to address some difficulties encountered in a flame cutter that cuts metal sheets based on an intelligent controller. In the existing system an optical sensor is used for the feedback that tracks the drawing-into 1:1 scale. The new proposal is to modify the entire system using stored-programs with feedback generated from shaft sensors. Thus the proposed system uses AUTOCAD software for drawing implementation. The application software developed in the project extracts the minimum information necessary for the controller from the AutoCAD file (DxF). This process creates a new file (information_file) containing the path information. A unique discretization process is proposed to generate suitable data points to the controller using the information_file. The algorithm developed minimizes the data points to be stored and to be sent to the controller as reference data. The controller, in essence, tracks the drawing within the given accuracy, while maintaining the correct flame speed. It is shown that a simple controller with cost-effective hardware can implement the contouring-controller for a flame cutter. Some experimental and simulated results are presented. The information necessary for a beginner to start-off with a contouring controller is elaborated

直流电机轮廓-一个实践经验

该系统的开发是为了解决基于智能控制器的火焰切割机切割金属片时遇到的一些困难。在现有的系统中，光学传感器用于跟踪绘制成1:1比例的反馈。新的建议是使用存储程序和轴传感器产生的反馈来修改整个系统。因此本系统采用AUTOCAD软件进行绘图实现。本项目开发的应用软件从AutoCAD文件(DxF)中提取控制器所需的最小信息。这个过程创建一个包含路径信息的新文件(information_file)。提出了一种独特的离散化方法，利用information_file为控制器生成合适的数据点。所开发的算法最大限度地减少了要存储并作为参考数据发送给控制器的数据点。控制器，在本质上，跟踪绘图在给定的精度，同时保持正确的火焰速度。结果表明，一种简单、硬件成本低的控制器可以实现火焰切割机的轮廓控制。给出了一些实验和仿真结果。必要的信息，为初学者开始与轮廓控制器阐述
