# VR Simulation and Implementation of Robotics: A Tool for Streamlining and Optimization
## 4 Case Study
### Production Process and Its Necessities  
The manufacturing process for these inspection involves the production of rotor pockets, which are treated as blanks and then forwarded to the next workstation to assemble the rotors. The production process runs 24 h a day and is divided into three shifts of 8 h each, with 1 h each shift serving as the insured value of the inventory. Material and information flows are managed according to JIT principles and the company manages it through an internal network with real-time connections to suppliers and customers. Control is performed by reading the code of the executed process, or directly by reading individual products, materials or semi-finished products. The structure of production line Z, shown in Figure 5, is used to describe and analyse the current status, and also represents the conceptual model for the subsequent design of the simulation model itself. At workplace Z, the production target is to grind the input material in the form of 8 kg aluminium blocks (or ingots--there is no difference) as the raw material for the rotor slots. It is important to maintain the quality of the input material in the form of 99.97% aluminium, otherwise, not only the quality of the product itself, but also its production process would be at risk, since this parameter is important when cooling the product. The production process begins by transporting aluminium ingots via a conveyor belt connected to an input material warehouse, where the company melts the incoming 900 kg of aluminium ingots into the required 8 kg aluminium ingots. The operator then feeds the block into a CNC milling machine. The CNC milling machine programme for a specific shift is determined by the programmer in the scheduler section based on the production plan for each period. After the milling process, the rotor pockets are transferred to another conveyor belt for cooling and marking the final stage of production of rotor pockets. The cooling process is meticulously orchestrated under a veil of secrecy, with temperature parameters carefully guarded as proprietary knowledge, bestowing upon the company a competitive edge withing the market. Following the completion of this phase, human operators delicately transfer the rotor pockets back to their respective handling units. These encased components are subsequently entrusted to a sophisticated logistics train, meticulously choreographed to navigate the intricate pathways traversing the company's premises. Operating within this workstation are stringent constraints, including predetermined production timelines for the milling of rotor pockets, the perpetual motion of materials along belt conveyors fixed in place by the company, and the exacting adherence to precise technological protocols and quality standards. Furthermore, meticulous attention is devoted to ensuring compliance with technical specifications governing production. The layout depicted in the visual representation of the Z production line in Figure 5 serves a dual purpose: elucidating the current operational framework while also furnishing a conceptual blueprint for the subsequent development of the simulation model itself.
