AI Technical Summary
Existing technologies lack a unified method for generating tool paths for machining the internal rotating surfaces of curved turning tools, resulting in limited machining accuracy and efficiency. Furthermore, they rely on operator experience, making it difficult to optimize the turning process and tool path.
By selecting the characteristic curve of the inner cavity rotation surface, the tool position data is calculated in different regions to generate the tool path of the curved turning tool, including the tool position calculation of the machining area and the inlet and outlet areas. Combined with machine tool performance and collision detection, the tool position data is automatically calculated.
It improves the machining accuracy and efficiency of internal cavity rotary surfaces, simplifies the tool path generation process, is applicable to bending turning tools of different sizes and shapes, and provides a data basis for optimizing turning processes.
