Controller Integrated Digital Twin – A Boost for Dynamics and Accuracy in Machine Tools and Robots

Digital Twins have gained prominence in various applications, including virtual commissioning and process optimization. However, their use in real-time control systems is relatively new. In this article, we explore an innovative approach where the Digital Twin describes dynamic features of both machine tools and robots, as already implemented in Sinumerik ONE. Two distinct approaches are presented. First, we delve into the SINUMERIK function called Engineered Motion Control (EMC) that uses the Digital Twin to improve the dynamic and productivity of a machine. Next, we address robot modeling. Unlike machines, robot dynamics significantly depend on the pose and requires a more complex model than maps those variations.
