A method for capturing data representative of a geometry of a raw cylinder head casting in order to obtain a casting scanning coordinate system for use with a machining coordinate system utilizes a locating device during a non-contact scanning operation. The cylinder head casting includes horizontal planar cast locators and vertical cast locators. Planar data corresponding to the planar cast locators is determined by scanning planar areas of the device. Vertical data corresponding to the vertical cast locators is determined utilizing locating features disposed on a planar surface of the device and located at predetermined positions with respect to the vertical cast locators. A transformation matrix defining a relationship between the scanning coordinate system and the machining coordinate system can then be determined based on the planar and vertical data so that virtual machining can be performed in predicting the volume of a machined cylinder head.
