A thorough investigation into the machining accuracy compensati

  • The prevention of dimensional and geometric errors are two of the most important goals to achieve.

    Thermal deformation error accounts for a significant proportion of the total error in a CNC machine, according to the manufacturer. The machining accuracy of a computer numerically controlled (CNC) machine can be influenced by a variety of factors, the most significant of which is thermal deformation error. This type of error is typically caused by the machine's internal and external heat sources transferring heat to the surrounding environment either through contact surfaces or radiation, resulting in the parts becoming heated and deformed as a result of the transfer of heat. When compared to other types of thermal deformation errors, multivariable thermal deformation errors have a large lag, exhibit nonlinearity, and have a strong coupling characteristic, among other characteristics. For example, it is critical to take into account factors such as heat source reduction, control of the heat transfer path, and increasing the thermal stability of the structure design when designing a structure in order to avoid such mistakes. Particularly effective methods of reducing the output of a steel CNC machining include regulating the heat source and heat, increasing the cooling and lubrication provided during operation, optimizing the machine's design and configuration, and regulating the temperature of the processing workspace according to the manufacturer's specifications. Heat is applied to the part in order to reduce the amount of deformation.


    Identification and avoidance of additional types of errors



    As a result of deformation of the spindle and fixture, it is possible to detect and correct machining errors, as well as to complete finish milling operations on the bottom surface of the cylinder head, using this probe.

    The accuracy should be maintained at 0.15mm/500mm or better throughout the process. The deformation elongation of the spindle and the deformation inclination error of the fixture are eliminated as a result of the effective application of probe compensation technology, and the machining accuracy of the spindle direction reaches + 0.025mm/500mm, further improving the machining accuracy of the machine tool.

    For the second, the correction amount tolerance zone, which is typically set to 0.4 (0.2), represents the upper limit of the amount compensated when compared to the amount compensated in the previous compensation and represents the maximum amount compensated.

    Accuracy in Hole Machining is compensated for by the amount of time it takes to complete the job.

    When it comes to improving the accuracy of a CNC machine, there are two primary methods to consider: error prevention and error compensation. Error prevention is the first method to consider. The first method to take into consideration is error prevention. This limitation has led to a lack of widespread adoption of the former method, which does not completely eliminate error and is prohibitively expensive to implement. In the machining industry, the error compensation method is a commonly used accuracy compensation method for compensating for errors. Through the use of error compensation, it is possible to achieve a significant and effective increase in the accuracy of a CNC machine. While it can only be used for a short period of time, it can assist in lowering the manufacturing costs of mechanical equipment while simultaneously increasing the economic benefits of the enterprise in question. In spite of this, the practical application of this precision compensation technology in a CNC machine continues to be fraught with difficulties, the majority of which are concentrated in the areas listed below.

    (3) Despite the fact that the CNC machining industry is underinformed about precision compensation technology, the industry has made insufficient investments in this field. Their NC technology does not have a true integration of precision compensation, which makes it difficult to make adjustments.

    Some precision compensation technologies are unable to be implemented effectively because of the technical limitations of CNC machines, which are limited in their ability to operate because of the low technical levels of those operating them.
