Abstract:
(EN) Provided is a piston manufacturing method including: a formation step for forming a reference surface on a crown surface of a piston; a processing step for processing a piston pinhole in a set position, with the reference surface as a positional reference in the piston axial direction; a measurement step for measuring a compression height, which is a distance from the piston pinhole to the reference surface; and an evaluation step for evaluating the piston axial direction position of the piston pinhole on the basis of the difference between the measured compression height and a distance reference value.
(FR) L'invention concerne un procédé de fabrication de piston comprenant : une étape de formation permettant de former une surface de référence sur une surface de couronne d'un piston ; une étape de traitement permettant de traiter un trou d’axe de piston dans une position définie, la surface de référence faisant office de référence de position dans la direction axiale du piston ; une étape de mesure permettant de mesurer une hauteur de compression, qui est une distance du trou d’axe de piston à la surface de référence ; et une étape d'évaluation permettant d’évaluer la position de direction axiale du piston du trou d’axe de piston sur la base de la différence entre la hauteur de compression mesurée et une valeur de référence de distance.
(JA) ピストン製造方法は、ピストンの冠面に基準面を形成する形成ステップと、前記基準面をピストン軸方向の位置基準として、設定された位置にピストンピン孔を加工する加工ステップと、前記ピストンピン孔から前記基準面までの距離であるコンプレッションハイトを計測する計測ステップと、計測されたコンプレッションハイトと距離基準値との差に基づいて、前記ピストンピン孔のピストン軸方向位置を評価する評価ステップと、を有する。
