摘要
本文展示了一种新颖的算法用以处理由直线、弧、自由曲线组成的凸或凹形的复杂槽腔的切削路径。首先用四点细分插值法对边界的数据加密,然后进行快速补偿。作者提出一种复式排序搜索方法计算补偿曲线的交点,最后判断剔除多余的自交环,得到数控加工刀具的切削路径。文章给出了一些复杂边界补偿结果的例子以示算法的效果。
It presents a new computation model for compensation complex pockets with conves and/or concave composed of straight line, arc and free curve. In the process a concise interpolatory scheme called 4-point interpolatory subdivition scheme is applied to densify control pointers. Then a quick compensation procedure is executed and a new method is developed for searching and calculating intersactory points caused by previous procedure. Finally, the seperation procedure is used and the false pieces are abandoned exactly.Some example is demostrated for the improvement of compensation complexity boundry.
