摘要
割缝补偿是热切割数控系统与CAM系统的核心功能之一,对该功能的重复开发是极大的浪费。在已有补偿算法基础上,研究了短小圆弧以及短小直线的补偿方式,推导了转接角为0°时直线-直线,直线-圆弧,圆弧-圆弧,圆弧-直线的补偿计算公式,设计出通用的割缝补偿算法。基于可重用的软件工程思想,利用面向对象的设计方法,采用静态工厂方法设计模式,将补偿算法与G代码解析功能封装为函数库组件,供相关控制系统及CAM系统调用,提高开发效率。组件已成功应用于数控切割机控制系统等。
Cutting gap compensation is a core function of numerical control systems and CAM systems, which is a great waste to develop the functions again and again. Based on existing algorithms, it studies the compensation methods of short arcs and short line, concluding the calculation formulas of line-line, line arc, arc-arc, arc-line situations when turn angle is zero, designing a common compensation of cutting slit algorithm. Based on reuse thinking of software engineering, it uses objectoriented design method and static factory method design pattern, encapsulates compensation algorithm and G-CODE parser function together to a secondary development component. NC systems and CAM systems can call the component to increase development efficieney. The component has been applied successfully in the control system of CNC cutting machine.
