Abstract: This paper addresses the need for developing new CNC computer cutting machines, analyzes the unique characteristics of CNC computer cutting machine control, and constructs an open CNC computer cutting machine system software architecture based on an industrial PC and the GD104 multi-axis motion control card as the core. The implementation technologies of key components are presented. Furthermore, a Windows-based CNC system software component was developed, utilizing object-oriented programming methods to achieve a user-friendly human-machine interface and a convenient and efficient multi-tasking working environment. Keywords: CNC cutting machine; GD104; Open CNC system As China's garment and footwear enterprises gradually align with international standards, the application of CNC cutting machines plays an increasingly crucial role in improving production automation, reducing the impact of human factors, improving product quality, reducing labor costs, lowering costs, and enhancing enterprise competitiveness. Since the materials processed in the cutting machine are multi-layered fabrics or leathers, these solid materials need to be processed into small pieces of various shapes and patterns. Therefore, the transition from the old, simple hand-push electric cutting machine to the modern large-scale computer-controlled garment cutting machine represents a significant transformation, known as a computer numerical control automatic cutting system. The hardware system of a shoemaking cutting bed system comprises five main parts: machine support, vacuum suction device, guide rails, cutting execution mechanism, and control circuitry. Figure 1 shows the hardware structure of an open CNC system for a computerized cutting bed constructed using a GD104 motion controller.
