FEATURE EXTRACTION FROM STEP AP224 FILE SETS
Keywords:
Feature Technology, NC Code generation, neutral file. Computer Aided Design (CAD), Computer Aided Manufacturing (CAM).Abstract
Feature technology transforms the low-level geometrical definition of a 3D model into high level
product definition, aiming for full automation of downstream manufacturing activities. Today,
feat ure has been implemented in STa ndard for Exchange of Product Model specifically in
Application Protocol 224 (STEP AP224) which utilizes manufacturing featu re definition based on
prismatic and turning parts, Hence, this research is carried out to study how STEP AP data is
stored and how the features can be extracted. The extracted features are then used to automate the generation of the NC Code for the milling process. This work is limited to isolated milling features on 2.5D parts or prismatic parts.
