This paper investigates the possibility of application different optimization techniques in design and production planning phase metal additive manufacturing process, specifically laser powder bed fusion (L-PBF) technology. technology has a significant market share belongs to group mature for end-use parts. In this technology, there is space additional cost/time reduction by simultaneously optimizing topology structure part orientations. Simultaneous reduces time and, indirectly, cost parts...

Traceability is widely recognized as being crucial for various software development-related applications, including maintenance, quality assurance, and change management. However, most existing approaches do not augment traceability relationships with semantics going beyond natural language descriptions, thus limiting the potential automatizing relevant activities such consistency checking or propagation. Based on a case study concerned preserving of business process model refinements, this...

One of the key elements digital manufacturing (including design-planning-production-inspection value chain) is a simulation i.e. virtual modelling all processes that belong to chain. Simulations are frequently used optimise some manufacturing, in order improve quality process itself and its output. This paper presents simulated, experimentation performed estimate effect computer aided inspection (CAI) parameters on measuring for sculptured surface inspection, using response methodology...
