This thesis project presents the rehabilitation and modernization of a three-axis TTT Machine that utilizes a hybrid actuation system made of pneumatic cylinders and a stepper motor that is equipped with an encoder. The machine which was previously used for automation demonstrations in the faculty, had resided in the robotics lab in a semi-assembled state after its relocation. This project’s ambition was to restore full functionality of the system through reverse engineering, careful reassembly, and control optimization using PLC based architecture. The main problems that are addressed include unclear physical wiring that has a lot of floating disconnected wires which made it hard to understand what element is connected to what other element, and a lot of relying on open loop control and lack of measurement data, coupled with some challenges in unifying the software experience to make all aspects of the machine observed and controlled from the same software. The steps towards finalizing this task involves detailed component analysis, integration of reliable sensor data and implementation of PLC control logic to control and measure the output of controlling the machine and enhance system performance. The outcome of this study is a reengineered TTT machine, where the pneumatic axles were renovated to up-to-date automation technology with improved test repeatability, control accuracy providing a good foundation for future automation experiments and educational purposes.
