Abstract
(EN) A numerical control device (1) comprises an information acquisition unit (371) and an instructions generation unit (372). The information acquisition unit (371) acquires workpiece shape information indicating the shape of a workpiece, which is rotated around a rotational axis and has a circular tube surface, and target site shape information indicating the shape of a target site for chamfering or deburring within the circular tube surface. On the basis of the workpiece shape information and the target site shape information that were acquired by the information acquisition unit (371), the instructions generation unit (372) generates, as interpolation instructions to be used in the chamfering or deburring of the target site, interpolation instructions that correspond to a shape resulting from expanding the target site onto a virtual plane, which comprises the rotational axis and an axis that is perpendicular to the rotational axis and is virtually produced by rotation.
(FR) La présente invention concerne un système de commande numérique (1) qui comprend une unité d'acquisition d'informations (371) et une unité de génération d'instructions (372). L'unité d'acquisition d'informations (371) acquiert des informations de forme de pièce indiquant la forme d'une pièce, qui tourne autour d'un axe de rotation et a une surface de tube circulaire, et des informations de forme d'emplacement cible indiquant la forme d'un emplacement cible pour le chanfreinage ou l'ébavurage à l'intérieur de la surface de tube circulaire. Sur la base des informations de forme de pièce et des informations de forme d'emplacement cible qui ont été acquises par l'unité d'acquisition d'informations (371), l'unité de génération d'instructions (372) génère, en tant qu'instructions d'interpolation destinées à être utilisées dans le chanfreinage ou l'ébavurage de l'emplacement cible, des instructions d'interpolation qui correspondent à une forme obtenue par l'expansion de l'emplacement cible sur un plan virtuel, qui comprend l'axe de rotation et un axe qui est perpendiculaire à l'axe de rotation et est virtuellement produit par rotation.
(JA) 数値制御装置(1)は、情報取得部(371)と、指令生成部(372)とを備える。情報取得部(371)は、回転軸を中心として回転され円筒面を有するワークの形状を示すワーク形状情報と、円筒面のうち面取りまたはバリ取りの対象箇所の形状を示す対象箇所形状情報とを取得する。指令生成部(372)は、情報取得部(371)によって取得されたワーク形状情報と対象箇所形状情報とに基づいて、対象箇所の面取りまたはバリ取りに用いられる補間指令として、回転軸と、回転軸と直交し回転により仮想的に発生する軸とからなる仮想平面上に、対象箇所を展開した形状に対応する補間指令を生成する。
