Analysis of NC data based on CNC data model for retaining machining information

Abstract

Retaining machining information is an important element for generating high quality machining information. However, existing NC data (ISO 6983) cannot be used for generating high quality machining information because they do not contain machining features, cutting tool information, workpiece information, and so on. In order to solve this problem, a method of retaining machining information (Workingstep) is proposed in this research. The Workingsteps are obtained by analyzing and transforming existing NC data to CNC data model (ISO 14649) which represents explicitly technical information, such as machining features, cutting tool information, workpiece information, and so on. In this report, the extraction of Workingteps and representation of relationship between them are described.
