在机械加工和计算机数控(CNC)领域,circular interpolation(圆弧插补)是一种控制工具沿圆弧路径运动的算法。它通过计算起点、终点和圆心(或半径)的坐标,生成中间点以实现平滑的圆弧轨迹。以下是详细解释:
基本功能
圆弧插补允许数控机床或机器人沿预定义的圆弧路径移动,而非仅限于直线。这是通过实时计算圆弧上的中间点坐标实现的。
数学原理
使用参数方程描述圆弧。例如,二维圆弧的参数方程可表示为:
$$
x = r cos(theta) + h
y = r sin(theta) + k
$$
其中,$(h,k)$ 是圆心坐标,$r$ 是半径,$theta$ 是角度参数。
CNC加工
用于钻孔、铣削圆形轮廓或复杂曲面(如齿轮齿形、凸轮)的加工。例如,G代码中的指令G02
(顺时针圆弧)和G03
(逆时针圆弧)即基于此原理。
机器人路径规划
确保机械臂末端执行器沿圆弧轨迹运动,适用于焊接、喷涂等需要连续平滑动作的场景。
3D打印与绘图
生成曲线路径以提高打印/绘图的精度和效率。
