Abstract:
(EN) The present invention relates to a nesting and cutting path optimization apparatus and method. In more detail, the nesting and cutting path optimization apparatus includes: a bitmap conversion unit, which acquires member information from a technical drawing for nesting and uses the acquired member information to convert members and a thick plate on which the members are disposed into a bitmap format having a preset resolution; a member placement unit, which sets a virtual diagonal line on a thick plate on which the member converted into a bitmap format will be disposed, and sequentially arranges members sequentially selected on the basis of an arrangement sequence, each of the members being arranged at the position at which the distance between the set virtual diagonal line and piercing points of the selected member is smallest, and the arrangement possibilities of the remaining members are greatest; and a member cutting unit, which with respect to the arranged members calculates the distances between a start position at which cutting is initiated and the piercing points of the arranged members, and selects the point at which the calculated distance is smallest as a piercing point to cut the members, the members being cut by selecting the piercing points in order of those closest among the piercing points.
(FR) La présente invention concerne un appareil et un procédé d'optimisation de trajet d'emboîtement et de coupe. Plus particulièrement, l'appareil d'optimisation de trajet d'emboîtement et de coupe comprend : une unité de conversion d'image matricielle, qui acquiert des informations d'élément à partir d'un dessin technique pour un emboîtement et qui utilise les informations d'élément acquises pour convertir des éléments, et une plaque épaisse sur laquelle les éléments sont disposés dans un format d'image matricielle présentant une résolution préétablie; une unité de placement d'élément, qui définit une ligne diagonale virtuelle sur une plaque épaisse sur laquelle l'élément converti dans un format d'image matricielle doit être disposé et qui agence séquentiellement des éléments sélectionnés séquentiellement, en fonction d'une séquence d'agencement, chacun des éléments étant agencé à la position à laquelle la distance entre la ligne diagonale virtuelle établie et les points de perçage de l'élément sélectionné est la plus courte et où les possibilités d'agencement des éléments restants sont les plus grandes; une unité de coupe d'élément, qui, par rapport aux éléments agencés, calcule les distances entre une position de départ à laquelle la coupe est lancée et les points de perçage des éléments agencés et qui sélectionne le point auquel la distance calculée est la plus courte en tant point de perçage pour couper les éléments, les éléments étant coupés par la sélection des points de perçage dans l'ordre des points de perçage les plus proches parmi les points de perçage.
(KO) 본 발명은 네스팅 및 절단 경로 최적화 장치 및 방법에 관한 것으로서, 더욱 상세하게는 네스팅을 위한 설계 도면으로부터 부재 정보를 획득하고, 상기 획득된 부재 정보를 이용하여 부재들 및 상기 부재들이 배치될 후판을 기설정된 해상도의 비트맵 형태로 변환하는 비트맵 변환부; 비트맵 형태로 변환된 부재가 배치될 후판에 가상의 대각선을 설정하고, 배치 순서에 따라 순차적으로 선택된 부재의 절단 지점들(piercing points)과 상기 설정된 가상의 대각선 간의 거리가 최소이고, 남은 부재들의 배치 가능성이 최대인 위치에 상기 선택된 부재를 순차적으로 배치하는 부재 배치부; 및 상기 배치된 부재들에 대해서, 절단을 시작하려는 출발 위치 및 상기 배치된 부재들의 절단 지점들 간의 거리를 계산하고 상기 계산된 거리가 최소인 지점을 절단 지점으로 선택하여 부재를 절단하되, 절단 지점들 중에서 인접한 거리가 최소인 절단 지점을 차례대로 선택하여 부재를 절단하는 부재 절단부를 포함한다.
