Cutting Tool Data Representation and Implementation Based on STEP AP242

Abstract

For cutting tool data exchange in manufacturing CAx (Computer-Aided technologies), standardized representation and classification of items and properties is important. ISO 13399 (Cutting tool data representation and exchange) provides a solution to represent cutting tool data classified with an ISO 13584 (Parts Library, PLib) based dictionary. However, ISO 13399 does not support classification of shape geometry directly, which limits its use. Another limitation is representing GD&T (Geometric Dimensioning and Tolerancing) as simplified general properties, which does not fulfill high semantic precision and validation rules. This research provides a unified solution to represent cutting tool parameters integrated with geometry and dedicated properties based on STEP AP242 (ISO 10303-242 Managed model-based 3D engineering). Standardized libraries such as the ISO 13399 dictionary can be reused with the modeling approach for AP242 cutting tool representation. Software is developed to validate and demonstrate how this solution facilitates the data integration process to support CAx applications.
