Abstract
Smart manufacturing using IOT technologies such as collaboration with high-level production systems, feedback of machining information to upstream processes, and pre-verification is attracting attention. In this context, the construction methods of so-called digital twin machines and various applications are beginning to be discussed. However, the current situation is that the application is limited to scheduling in the shop floor and the whole factory. In this research, we propose a digital twin that realizes machining motion function of multi-axis machine tool in cyber space by multi-axis machine tool model and machining shape simulation. In addition, as an application example of digital twin, we propose an application system for process planning by real and virtual machining cases created by real machine tool and digital twin.
