Constraint Identification from STEP AP242 files for Automated Robotic Welding

This article proposes the use of STEP AP242 for identifying and extracting the relevant product data for constraint-based programming of welding robots. Most of the product data is created during the design phase of its life cycle. This data can be reused in downstream processes employing Digital Thread as part of Industry 4.0 practices. This article proposes using STEP AP242 Edition 2 neutral file exchange format for extracting geometry and Product Manufacturing Information. This article discusses various types of constraints and welding information that can be included in STEP AP242 files and extracted for automated programming and real-time control of robotic welding operations.
