Production technology studies are the most important step in determining the infrastructure to be established for production. This study starts with a detailed analysis of the product. Product function, dimensions, tolerances, materials, product variety, etc. are evaluated in all aspects. Afterwards, the production processes are determined to be most suitable for the product and optimized in accordance of experience from similar processes. A production concept is created in accordance with customer needs, local production conditions and capacity needs. The process flow is created, process inputs and outputs are defined. In the design phase, it is evaluated whether the process is manual, automatic or semi-automatic. The equipment and key technologies are determined. Soft simulation of the process or, real simulations can be made with the same real part and planned equipment. The process design is optimized according to the simulation outputs. In addition, process FMEA studies are carried out according to the needs. After the completion of the process design, prototype product production is critical in equivalent process conditions. Open points for improvement, which are often detected in prototype process production, constitute important inputs to product and process design. Finally, the results obtained from the process studies are reported to provide input to the automation stage.
