PROGRESSES IN THE DEVELOPMENT OF A STEP-NC COMPLIANT ADDITIVE MANUFACTURING SYSTEM

Blog Article

The new standard of numerical control, known as STEP-NC, is categorized as the future of the advanced manufacturing systems.Greater flexibility and interoperability are some potential benefits offered by STEP-NC to meet the challenges of the new industrial landscape that is envisaged with the advent of Industry 4.0.Meanwhile, STEP-NC object-oriented programming has been partially applied and developed for machining processes (milling, turning.

).But with the processes of additive manufacturing Course a pied - Accessoires - Gants has not happened the same and the development is still incipient.This work presents the advances in the development of a new STEP-NC compliant additive manufacturing system, focusing particularly on the development of the information model.The application model activities in the IDEF0 nomenclature and application reference model in EXPRESS are presented.

The AM-layer-feature concept has been introduced to define the manufacturing feature of additive processes based on material deposition layer-by-layer.Finally, a STEP-NC program generated from the Gas Safety Valve EXPRESS model is presented, which can be implemented on an additive manufacturing system to validate the proposed model.
