Abstract
In this paper, the five-axis linkage machining technology of complex curved parts is comprehensively studied, and the unique advantages and key technical points of five-axis CNC machine tool in machining complex curved parts are deeply analyzed. Through detailed analysis of key links such as 3D modeling and machining path planning, this paper reveals the significant advantages of five-axis linkage machining technology in improving machining accuracy, flexibility and efficiency. However, the current technology still faces challenges in practical application such as high equipment cost, high technical threshold, machining accuracy and stability to be improved, programming and simulation difficulty, and complex tool and fixture design. To address these challenges, this paper proposes a series of innovative optimization suggestions. In terms of reducing equipment costs and technical thresholds, it is recommended to optimize equipment procurement strategies, promote the research and development of low-cost five-axis machining technology, and strengthen technical training and personnel training. In order to improve machining accuracy and stability, this paper discusses the optimization of high precision servo control system, dynamic error correction strategy during machining, and the importance of implementing multi-stage accuracy verification and adjustment mechanism. In addition, aiming at the difficulty of programming and simulation, this paper advocates the development of user-friendly graphical programming interface, the establishment of standardized programming template library, and the integration of automatic collision detection and obstacle avoidance functions. In the aspect of tool and fixture design, this paper puts forward the specific strategies of innovating tool material and structure, optimizing clamping force distribution and developing intelligent tool management system.
