Abstract
Such manufacturing cells, that need to be able to produce high quantity and variety workpieces, the automatic workpiece handling is indispensable to stay in competition. A real manufacturing cell’s simulation in a cyber-physical system can help the decisions-making in the production, as we receive real data with the simulation of the scenarios. Our manufacturing cell consists of a 6-axis robot, 2 CNC milling machines and 4 conveyors. We tested 10 different scenarios, during which we analyzed the usage of the robot and the milling machines. By upgrading the tools, used for milling, we could reduce the cycle time of the workpieces. Furthermore, one more milling machine could be integrated into the cell due to the low usage of the robot or the speed of the robot could be lowered. Besides, filling the pallets with the same workpieces was the most effective way, however, with mixed workpieces we reached better results when we used optimization for cycle time. In these cases, reducing the order quantity to a daily amount did not cause any capacity reduction.

Summary
The industrial robots are important parts of the manufacturing systems they use them in a wide variety of application due to advantages, offered by them. The applications they use them in are welding, material handling, assembly and painting. The benefits of industrial robots are the high reliability, precision and repeatability. After the robot's program is written correctly, the certain operations can be achieved rapidly and precisely [1]. Programming these industrial robots are still hard and time-consuming tasks. For instance: programming manually a robotic arc welding system for the manufacture of a large vehicle hull takes several months [2]
