【摘要】 复杂区域之间距离的计算在平面布局、干涉检验、ＣＡＤ／ＣＡＭ等领域具有广泛的应用。本文提出了基于二元可微函数在矩形区域中最小值的距离计算方法，论述了基本思想及算法实现。算法不含迭代求解过程，计算量小，简便易行，符合应用实际。最后给出了ＣＡＤ／ＣＡＭ领域中，加工刀具半径的选取、螺旋式下刀方式参数的确定等应用实例。更多还原

【Abstract】 It is important to compute the distance between regions in some fields such as packing problems,collision detection and CAD/CAM A method based on minimum of differentiable function in rectangular region is proposed to compute distance between complex regions The principle and detail procedure are discussed In the end,three applications of distance between complex regions in CAD/CAM are provided.更多还原
