Develop a postprocessor for 5-axis CNC machines head-table type and head-head type based on determining coordinate transformation matrices

To translate data from CAM software into machine-readable G-code and M-code commands that can execute cutting and shaping movements, it is necessary to convert them to suitable commands for different CNC control systems. Compiling data for 5-axis CNC machines is much more challenging than for 3-axis and 4-axis machines, especially for 5-axis CNC machines with rotating heads, because the machining program, once compiled into G-code and M-code data, depends not only on the CNC control system but also directly on the length of the tool and the position of the coordinate origin. This study utilizes a new approach to develop a postprocessor software for 5-axis CNC machines with rotating heads, which takes standard CL Data was used as input and outputs G-code commands that can be executed by various CNC control systems. This software is independent of CAM software and can be compatible with different CNC control systems. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.
