In this thesis, we present the development of robotic manufacturing cell for CNC machine handling, which we faced in the manufacturing process of machining aluminum castings parts. Using the ABB RobotStudio software, we created a 3D model of our robot cell, in which we tested and analyzed different concepts. Using software tools for performing analyzes in a virtual environment allowed us to perform various evaluations and optimizations even before the robot cell was built in a real environment. Each evaluation was performed with at least three concepts. In the final part of our thesis, we obtained the results and explain the best choice of the most suitable industrial robot, robot grippers and robot manufacturing cell for our company. In addition, based on the simulations used and on the basis of time analyzes, key information of various robotic trajectories was obtained and the timing of the implementation of the various robotic trajectories. On this basis the most optimal industrial robot trajectory was determined.
