Abstract
(EN)
An interference detection method for cutter radius compensation, comprising: acquiring a programming trajectory (505); calculating a cutter-to-side edge trajectory (52) of the programming trajectory; determining whether the cutter-to-side edge trajectory intersects with a comparison programming trajectory (502); if the cutter-to-side edge trajectory intersects with the comparison programming trajectory, determining that the programming trajectory and the comparison programming trajectory will interfere with each other. The present invention further relates to an interference detection apparatus for cutter radius compensation, and further relates to an apparatus that has a storage function. The precision and usefulness of the described interference detection method for cutter radius compensation are improved.

La présente invention porte sur un procédé de détection d'interférence permettant une compensation de rayon de dispositif de coupe, consistant : à acquérir une trajectoire de programmation (505) ; à calculer une trajectoire dispositif de coupe-bord latéral (52) de la trajectoire de programmation ; à déterminer si la trajectoire dispositif de coupe-bord latéral croise une trajectoire de programmation de comparaison (502) ; si la trajectoire dispositif de coupe-bord latéral croise la trajectoire de programmation de comparaison, à établir que la trajectoire de programmation et la trajectoire de programmation de comparaison interfèrent l'une avec l'autre. La présente invention concerne en outre un appareil de détection d'interférence permettant une compensation de rayon de dispositif de coupe, et porte également sur un appareil qui dispose d'une fonction de stockage. La précision et l'utilité du procédé de détection d'interférence permettant une compensation de rayon de dispositif de coupe décrit sont améliorées.
