摘　　要：针对海绵切割系统连续切割路径优化问题,提出一种基于碰撞检测的蛇形排序方法。首先通过优化样片的切割起点和切出点,生成合理加工过渡线,使重复路径长度与样片之间的过渡加工路径长度最小。然后通过蛇形排序方法,生成上下往复的切割顺序,避免切割路径杂乱无章。搜索到目标样片后,通过碰撞检测方法判断当前加工过渡线是否与其他样片轮廓相交,并根据判断结果优化样片切割顺序,尽量避免跨样片切割,保证加工路径满足海绵切割系统的连续加工约束。最后利用该方法对60个海绵样片切割路径优化问题进行求解,得到一条满足加工约束的路径,进一步验证了所提方法的有效性。Aiming at the optimization problem of the continuous cutting path of the sponge cutting system,a serpentine sorting method based on collision detection was proposed.Firstly,by optimizing the cutting starting points and cutting out points of the samples,a reasonable processing transition line was generated to minimize the length of the repeated path and the transition processing path between the samples.Then,through the serpentine sorting method,a cutting sequence of up and down was generated to avoid the chaotic cutting path.After searching for the target sample,the collision detection method was used to judge whether the current processing transition line intersects with the contours of other samples,and the cutting sequence of the samples was optimized according to the judgment result,which can avoid cutting across samples and ensure the processing path satisfied the continuous processing constraints of the sponge cutting system.Finally,this method is used to solve the optimization problem of the cutting path of 60 sponge samples,and a path that satisfied the processing constraints is obtained,which verifies the effectiveness of the proposed method.
