THREE-DIMENSIONAL INTERNAL INFORMATION ACQUISITION SYSTEM BASED ON CONSECUTIVE PRECISION MACHINING AND CROSS-SECTIONAL OBSERVATION: DEVELOPMENT OF THE SYSTEM AND ITS APPLICATIONS

摘要

An automated system was developed to acquire three-dimensional information from metallurgical and biological specimens. The system is based on consecutive precision machining and cross-sectional image recording. In the system, face milling by a single crystal diamond tool is used for high precision machining, and an optical microscope is used for cross-sectional image recording.rnThe system enabled three-dimensional analyses of casting defects in a die casting alloy specimen, and three-dimensional microstructure observation of biological samples containing hard tissues.
