3D image rendering for virtual reality HMDs is typically generated based on a set of parameters taken from the manufacturer-supplied specifications and an idealised perspective model. But actual displays may vary in build features that alter spatial perception. Moreover, the eye focusing effort is often ignored. The resulting visual discomfort and incorrect geometry perception has discouraged use...
This paper presents the process to construct a digital twin for a sheet metal punching machine to support the interactive design of optimal NC machining programs. The results show that this entity manages to simulate interactively the basic behaviour of the actual sheet metal machine: movements, machining operations and connectivity with robotic arms. Using Ethernet/IP communication protocol, Digital...
FEA simulation of thermal metal cutting is central to interactive design and manufacturing. It is therefore relevant to assess the applicability of FEA open software to simulate 2D heat transfer in metal sheet laser cuts. Application of open source code (e.g. FreeFem++, FEniCS, MOOSE) makes possible additional scenarios (e.g. parallel, CUDA, etc.), with lower costs. However, a precise assessment is...
