Engineering Contradiction Analysis
1Object-generated harmful factors
If multiple feed axes are simultaneously oscillated to perform oscillating cutting on tapered or arc-shaped workpieces, then chip shredding is achieved, but a large load is imposed on the machine tool
Solution Approach 1:
The patent extracts the oscillation function from multiple feed axes and concentrates it on a single oscillation axis. The oscillation control unit generates oscillation commands for only one specific axis (e.g., Z-axis or X-axis) based on workpiece shape and tool movement data, while other feed axes operate normally without oscillation commands. This extraction reduces the number of axes requiring oscillation control and minimizes machine tool load.
2Force
If the oscillation direction is changed from along the machining path to a different direction to reduce machine tool load, then load reduction is achieved, but the effect depends on the specific machine tool configuration
Solution Approach 1:
The patent dynamically changes the oscillation axis selection parameter based on workpiece shape and tool movement characteristics. The oscillation control unit determines whether to oscillate the Z-axis or X-axis by evaluating parameters such as workpiece geometry (tapered, arc-shaped, cylindrical) and tool movement direction. This parameter-based selection ensures effective chip shredding while adapting to different machine tool configurations and minimizing load on the specific axis being oscillated.
3Device complexity
If only one specific axis is oscillated instead of multiple axes, then control is simplified and machine tool load is reduced, but the selection of which axis to oscillate becomes complex and places workload on the user
Solution Approach 1:
The oscillation control unit performs self-service by automatically selecting the appropriate oscillation axis based on workpiece shape data and tool movement data. The system evaluates the workpiece geometry and tool path, then autonomously determines whether to oscillate the Z-axis or X-axis without requiring user intervention. This automation eliminates the burden on users to manually select the oscillation axis while maintaining optimal chip shredding performance.
4Manufacturing precision
If multiple feed axes are used to feed the cutting tool along the machining path for tapered or arc-shaped workpieces, then accurate machining is achieved, but a large load is imposed on the machine tool
Solution Approach 1:
The patent extracts the oscillation function from multiple feed axes and concentrates it on a single oscillation axis. The oscillation control unit generates oscillation commands for only one specific axis (e.g., Z-axis or X-axis) based on workpiece shape and tool movement data, while other feed axes operate normally without oscillation commands. This extraction reduces the number of axes requiring oscillation control and minimizes machine tool load.
