Title (EN) METHOD FOR VISUALLY CHECKING PORTIONS LEFT ROUGH OF A COMBUSTION ENGINE CYLINDER HEAD BLANK
(FR) PROCÉDÉ DE CONTRÔLE VISUEL DE PORTIONS LAISSÉES BRUTES D'UNE ÉBAUCHE DE CULASSE DE MOTEUR THERMIQUE
Abstract:
(EN) The invention concerns a method for visually checking portions (2) left rough during the finishing of a blank of a combustion engine cylinder head (1) delimiting at least one combustion chamber, the portions (2) left rough needing to be free of surface defects, the cylinder head (1) also having portions (3) to be machined. The portions (3) to be machined are concealed during the visual check, only leaving the portions (2) left rough visible to an operator carrying out a visual check of the surface of these portions (2) left rough, the portions to be machined being concealed by introducing an inspection template onto and into the cylinder head (1).
(FR) L'invention porte sur un procédé de contrôle visuel de portions laissées brutes (2) lors d'une finition d'une ébauche d'une culasse (1) de moteur thermique délimitant au moins une chambre de combustion, les portions laissées brutes (2) devant être exemptes de défaut de surface, la culasse (1) présentant aussi des portions à usiner (3). Le contrôle visuel se fait avec un masquage des portions à usiner (3) en ne laissant apparentes pour un opérateur que les portions laissées brutes (2) pour un contrôle visuel de surface de ces portions laissées brutes (2), le masquage se faisant par introduction d'un gabarit de contrôle sur et dans la culasse (1).
