By analyzing the characteristics and limitations of conventional hole processing technology, the secondary development of spiral milling hole is studied based on SinuTrain. By using the extended user interface programming method, the secondary development of spiral milling HMI and the secondary development of 2 D and 3 D spiral milling user fixed cycle instructions are completed. Based on the input of spiral milling hole parameters in HMI, the machining program is programmed automatically with spiral milling hole fixed cycle instruction, and the simulation experiment is carried out in the SinuTrain NC virtual prototype. The results show that the helical milling hole HMI meets the design requirements;the fixed cycle function of spiral milling hole is perfect, the program runs stably, the tool track is correct, and the machining accuracy is reliable.
