Following the pervasive trend of increasing artificial intelligence adoption, various technological processes are striving to enhance their capabilities through its utilization. An intriguing combination present within this trend is the integration of the manufacturing industry and artificial intelligence. Unsurprisingly, the objective of linking artificial intelligence and technological process design is to improve efficiency and product quality while reducing production costs. Within the scope of this thesis, the primary focus will be on providing a detailed description of technological process design, encompassing its various types and subtypes, as well as the evolution of computer-aided technological process design. Subsequently, it will be illustrated and elucidated the concept of Industry 4.0, including the technologies applied as part of the fourth industrial revolution. Then, the potential synergies between Industry 4.0 and computer-aided technological process design will be presented, analyzing the applications of artificial intelligence technologies within Computer-Aided Process Planning (CAPP). Finally, through three case studies, the application of artificial intelligence technology within CAPP will be showcased, and their results will be analyzed.
