With the continuous development of production technology, 5-axis linked machines have unique advantages in manufacturing parts with complex shapes. However, the accuracy of 5-axis linked machining centers is affected by a variety of factors, including structural design, tilting rotary axis accuracy, control system, tooling and cutting parameters, as well as the machining environment and process system. This paper will make some suggestions on how to improve the machining accuracy of 5-axis linked machines.
First of all, it is necessary to ensure that the structural design of the machine tool is reasonable. The precision of 5-axis linkage machine tools is determined by three linear axis precision and two rotary axis precision. Therefore, when designing the machine tool, it is necessary to consider these factors and ensure that the structure of the machine tool can meet the requirements of machining accuracy. For example, a new idea of bed structure design of five-axis CNC machine tool can be proposed by extracting the biological structure law and configuration characteristics, and the bed structure and performance can be analyzed to improve the rigidity and stability of the machine tool.
Secondly, it is necessary to ensure the accuracy of the tilting rotary axis of the machine tool. The accuracy of the tilting rotary axis is one of the important factors that affect the machining accuracy. When purchasing a five-axis engraving machine, you need to consider the structure, tilt rotary axis precision, interference anti-collision function, center of rotation correction and other factors. In the process of use, it is necessary to regularly calibrate and maintain the tilt rotary axis to ensure its accuracy.
Third, it is necessary to ensure that the control system of the machine tool is stable. The control system is one of the core components of the machine tool, and its stability directly affects the machining accuracy. When purchasing machine tools, you need to choose a reliable manufacturer to ensure the stability of the control system. At the same time, in the process of use, the need for regular maintenance and upgrading of the control system to ensure the stability of its performance.
Fourth, to choose the right tool and cutting parameters. The tool and cutting parameters are one of the important factors affecting machining accuracy. When selecting tools and cutting parameters, comprehensive consideration needs to be made according to factors such as the material, shape and size of the part. At the same time, the tool needs to be inspected and maintained regularly to ensure its sharpness and precision.
Finally, it is necessary to ensure the stability of the machining environment and process system. The stability of the machining environment and process system is also one of the important factors affecting machining accuracy. When using the machine tool, it is necessary to ensure that the temperature, humidity and cleanliness of the processing environment meet the requirements. At the same time, it is necessary to develop a reasonable process flow and operating specifications to ensure the stability of the machining process.
In summary, improving the machining accuracy of 5-axis linkage machine tools needs to be considered and improved from various aspects. Only through reasonable design, stable control system, suitable tools and cutting parameters and stable machining environment and process system can ensure the machining accuracy and efficiency of the machine tool.
