ISO 14649 (STEP-NC): New Standards for CNC Machining
The changing economic climate has made global manufacturing a growing reality over the last decade, forcing companies from east and west and all over the world to collaborate beyond geographic boundaries in the design, manufacture and assemble of products. The ISO10303 and ISO14649 Standards (STEP and STEP-NC) have been developed to introduce interoperability into manufacturing enterprises so a...
متن کاملDealing with feature interactions for prismatic parts in STEP-NC
Determining the precedence of machining features is a critical issue in feature-based process planning. It becomes more complex when geometric interaction occurs between machining features. STEP-NC, the extension of STEP (ISO 10303) standard developed for CNC controllers, is a feature-based data model. It represents all the geometric and topological product data minus feature interactions. In t...
متن کاملISO 14649-based nonlinear process planning implementation for complex machining
Increasing attention is being paid to complete machining, i.e., machining of the whole part in a single machine tool, in the metal working industry. For this purpose, complex machine tools equipped with machining components, such as multiple spindles and turrets have been developed by leading machine tool builders. The efficiency of complex machine tools is largely dependent on how the machinin...
متن کاملTesting Step-nc Implementations
STEP (STandard for the Exchange of Product model data, ISO 10303) data for numerical control, or STEP-NC, is intended to provide full product and process data interoperability between computer-aided manufacturing systems and machine tool controllers. Numerous prototype and several commercial implementations of STEP-NC are currently being developed. Testing is an essential step toward ensuring c...
متن کاملA STEP-Compliant Intelligent Process Planning System for Milling
The new standard ISO 14649 provides CAD/CAPP/CAM/CNC with an interface and a comprehensive high level and detailed manufacturing information. CNC technology based on STEP-NC will be the future trend, and the intelligent process planning is the core of STEP-NC oriented CNC technology. The objective of this research is to present the architecture, key technologies and implementation of STEP-NC or...
