To compensate the machining accuracy of the CNC machine tool is influenced by machine tool parts, the external environment and other factors. Therefore, it is necessary to add appropriate compensation parameters to ensure the stability of machining accuracy. In addition, the compensation parameters of different lathes change at different times in real time. Therefore, an improved Apriori algorithm and an intelligent error compensation model which based on artificial intelligence proposed to establish an intelligent and accurate real- time parameter compensation scheme for the running lathe. The factors that affect the machining accuracy, such as the condition of components and the external environment, form several eigenvalues. Each eigenvalue corresponds to several compensation parameters. A data set consists of several eigenvalues, compensation parameters and a precision value. Several data form a data set. The result of the simulation tests show that the stability of the lathe is improved by 0.695 and 0.713 for the data of the training set and the test set, respectively. The measurement results show that 30 products are carved with the above method, and the accuracy meets the requirements. Therefore, the intelligent error compensation model can improve the stability of turning processing and product qualification rate.
