Tiivistelmä
This master's thesis is about the role of the Digital Twin in product development. The product that is needed to develop in this project is plywood panel repairing line which is working is Raute Company. This machine is used in a step of producing plywood or LVL panels. Cartesian robots are working through the line to repair the defects on the panels. In order to boost the efficiency of the product line, high velocity and precision are needed. Therefore Festo toothed belt axes is replaced by linear motors.
In order to use the Digital Twin in improving the new design of the machine. Mevea software is utilized to create a real-time simulation. Mevea provides facility to connect the simulation to the controller that is designed in Simulink. The controller has played the crucial role in the simulation because the planning task and requirement of movements should be changed in controller design. Hence, it provides the access to update the system anytime.
The control system is designed based on controlling the position related to the velocity. It is important to control how to reach the target points. The electrical force that is generated by linear motors is controlled based on the velocity profile then send to the simulation to move the Cartesian motors. The results of the real-time simulation represent if the linear motor supplied enough force, the Cartesian robots move fast and reach the target points with acceptable accuracy.
