Title: Design of a Micro EDM Soft-CNC System Based on RTLinux
Abstract: This paper presents the development of a soft-CNC system for three-dimensional micro-electrical discharge machining (EDM) using an industrial computer and the RTLinux platform. Building upon the previously designed system framework, a soft-CNC module was developed under the RTLinux kernel using a modular approach. This allowed the digital control system to be fully implemented in software, while also introducing a dual-buffer mechanism for efficient data transmission. Experimental results demonstrated the reliability and practicality of the proposed system in micro-EDM applications.

Previous: Automatic 3D Modeling of Axial Pumps            Next: What to Pay Attention to Before Using an Electric Hammer? This paper explores the integration of real-time operating systems with precision manufacturing technologies, particularly in the field of micro-electrical discharge machining. By leveraging the capabilities of RTLinux, the authors have successfully created a flexible and reliable soft-CNC solution that can be easily adapted for different types of micro-scale operations. The use of a modular design not only enhances system stability but also allows for future expansion and customization. Additionally, the implementation of a dual-buffer data transfer mechanism ensures smooth and efficient communication between the control system and the machine tool, which is crucial for maintaining high accuracy during complex micro-machining tasks. The experimental results presented in this study confirm the effectiveness of the system, making it a valuable contribution to the field of advanced manufacturing technologies.
