In modern industrial production, non-conventional manufacturing processes are increasingly utilized alongside conventional methods for cutting materials, particularly in the case of sheet metal to obtain raw materials for further processing or finished parts for final assembly in products. Enhancing the quality of these processing systems ensures satisfactory accuracy and processing quality while maintaining high productivity and economy. Understanding the characteristics of individual manufacturing processes, including their capabilities and differences, facilitates manufacturing process planning by aiding decisions about optimal processes for specific conditions and when to employ them. The primary focus and objective of this research involve conducting a comparative techno-economic analysis of cutting steel sheets of C45 using laser, plasma, and flame cutting machines within the production conditions of a single production system. Input variables include the type of non-conventional cutting process/machining system, steel sheet thickness, and processing speed, while techno-economic analysis criteria encompass dimensional and geometric accuracy, material utilization, surface roughness, processing time, and cost.

摘要

In modern industrial production, non-conventional manufacturing processes are increasingly utilized alongside conventional methods for cutting materials, particularly in the case of sheet metal to obtain raw materials for further processing or finished parts for final assembly in products. Enhancing the quality of these processing systems ensures satisfactory accuracy and processing quality while maintaining high productivity and economy. Understanding the characteristics of individual manufacturing processes, including their capabilities and differences, facilitates manufacturing process planning by aiding decisions about optimal processes for specific conditions and when to employ them. The primary focus and objective of this research involve conducting a comparative techno-economic analysis of cutting steel sheets of C45 using laser, plasma, and flame cutting machines within the production conditions of a single production system. Input variables include the type of non-conventional cutting process/machining system, steel sheet thickness, and processing speed, while techno-economic analysis criteria encompass dimensional and geometric accuracy, material utilization, surface roughness, processing time, and cost.
