Abstract
The machining accuracy of mechanical components, as a critical indicator in modern manufacturing, directly impacts product performance and reliability. With the rapid development of industrial technology, requirements for machining accuracy have become increasingly stringent, yet the influencing factors are complex and diverse, necessitating in-depth research to optimize machining processes. This study aims to systematically analyze the primary factors affecting the machining accuracy of mechanical parts and propose targeted improvement measures. By integrating theoretical analysis with experimental validation, this research selects typical machining scenarios and investigates multiple dimensions including material properties, machine tool performance, cutting tool parameters, environmental conditions, and operational standards. The results indicate that the compatibility between material hardness and cutting parameters significantly influences surface roughness and dimensional accuracy, while thermal deformation and vibration of machine tools are important causes of geometric errors. Additionally, changes in environmental temperature and humidity indirectly affect machining stability. Innovatively, this study introduces a multi-variable coupling analysis model to quantify the contribution of each factor and develops a data-driven machining accuracy prediction tool, providing a scientific basis for actual production. The final conclusion demonstrates that optimizing cutting parameters, improving machine tool structural design, and enhancing environmental control can effectively enhance machining accuracy, offering significant references for precision machining in high-end manufacturing fields.
