The four-axis linkage machining technology is mainly used to machine workpieces with more complicated curved surfaces. Compared with the three-axis linkage machining, the four-axis linkage machining can process higher quality and more complex curved surfaces, which are mainly suitable for aircraft, mold, automobile and other industries. Special processing. At present, domestic four-axis machine tools have been popularized, and the machine tool price and maintenance cost are lower than imported machine tools, which is very important for a developing enterprise. Since the tool path in four-axis simultaneous machining has changed from a simple two-dimensional tool path to a complex three-dimensional tool path. The calculation of the cutting speed is more complicated, and the cutting speed of each cutting point is varied. This paper takes the turbine blade machining tool path as an example to analyze the tool feed speed and the corresponding special post-processing software development method.
