Title (EN) METHOD OF PREPARING NC DATA FOR COARSE MACHINING
(FR) PROCEDE DE PREPARATION DE DONNEES PERMETTANT LE DEGROSSISSAGE
Abstract:
(EN) A method of preparing NC data for coarse machining, wherein a path (QLi) for coarse machining is produced using points on an i-th point train path (PLi) among a plurality of point train paths that are repetitively digitized at predetermined intervals along a predetermined direction, and the next path for coarse machining is prepared and is produced using a projected point train path (PLk') closest to the i-th projected point train path (PLi') among the projected point train paths that are distant by more than a tool radius (Tr) on an XY projected plane.
(FR) Procédé de préparation de données NC permettant le dégrossissage, dans lequel une trajectoire (QLi) de dégrossissage est produite grâce à des points situés sur une ième trajectoire (PLi) de trains de points entre une pluralité de trajectoires de trains de points numérisés itérativement à des intervalles prédéterminés dans une direction prédéterminée, et la trajectoire suivante de dégrossissage est préparée et produite au moyen d'une trajectoire (PLk') de trains de points projetés, la plus proche de l'ième trajectoire (PLi') de trains de points projetés entre les trajectoires de trains de points projetés, qui sont distantes de plus d'un rayon d'outil (Tr) sur un plan à projection XY.
