STEP-based process information models for additive manufacturing application to fused deposition modelling

Abstract

 The implementation of AM digital thread mainly depends 
on modelling data and process, and the usage of standards 
considering all activities related to AM. In this paper, we firstly 
propose a fundamental procedure of building information 
system in fused deposition modelling (FDM), including process 
concepts, related standards, model representation and model 
evaluation from part design information to manu-facturing 
data. STEP-based process data models focusing on application 
reference model (ARM) and application activity model (AAM) 
are proposed to represent data transfer. In addition, process 
data model defines deposition process, process plan ac-tivity, 
deposition parameter, FDM requirement, specification, and 
FDM material, and redefines application entities and deposition 
operations, including 2.5D manufacturing layer, print header, 
FDM technology, deposition strategies, FDM functions and 
head path. Finally, Process data model needs to be evaluated to 
assess a conform-ance testing for verification and validation of 
these manufacturing data.
