| Popis: | Treball desenvolupat en el marc del programa "European Project Semester". Even though new systems like 3D printing start to get more viable, casting remains an important manufacturing technology. During a casting process, some segments at different spots of the material at the microscopic level are solidifying. Those are called grains, and they greatly influence the mechanical properties of the material. To increase the material properties the material science part (CDAL) of the UPC started with the development of a viscosity analysis prototype. This prototype analysis the viscosity, but the measured data is not accurate enough and the casting process doesn´t stop automatically. For this reason, the results from the previous group were analyzed and the existing inputs and outputs were described. With this information the main tasks were started, that include designing a case for the prototype, developing a viscosity model, doing research on viscosity and developing a software solution for the existing prototype. The results of those tasks lead to a safety increase through the case, an accurate viscosity analysis and an automated closed loop system to control the viscosity analysis. This system is now able to read the torque and speed values via Modbus, calculate the viscosity for various materials, include safety features, provide an interface and to enable customization through a maintenance window. Only the problems with the Festo motor control couldn`t be solved, due to the high complexity and communication problems between the devices. Further development could be to integrate the two motors into the program. To simplify that, replacing the motor and its control system is recommended. Incoming |
