2 April news, data from the National Intellectual Property Administration shows that AVIC Xi’an Aircraft Industry Group Co., Ltd. has applied for a patent titled “Automatic G-code Conversion and Vector Calculation Method.” The application publication number is CN121764470A, application number is CN202511804990.9, publication date is March 31, 2026, application date is December 3, 2025, inventors are Wang Zhen, Fan Di, Zhou Zhi Kang, Wang Yuguang, Meng Xianben, Liu Xueliang, Zhao Liang, Zhang Yanyan, patent agency is China Aviation Patent Center, patent agent is Wen Huijuan, classification numbers G06F8/40, G06F8/41, G06F17/10, G06F17/16.

The patent abstract indicates that the invention relates to the field of CNC machining of aircraft components, specifically a method for automatic G-code conversion and vector calculation. It includes: analyzing the structural features of the original and target machine tools and deriving suitable tool vector formulas and tilt angle formulas for both; extracting tilt angle data from the original machine tool’s G-code processing program; using the original tool vector formula and extracted tilt data to calculate the corresponding i, j, k vector values and substituting into the target machine tool’s tilt angle formula to derive the required tilt angles; performing tilt distance processing based on whether the original and target machine tools have a swivel center distance to meet the processing requirements; generating new G-code programs suitable for the target machine based on the derived tilt angles and processed actual machining coordinates, completing automatic G-code conversion and vector calculation. This achieves automatic conversion of G-code for CNC machines with different tilt axes.
