Innovation Solution
A microfabrication device and method that includes a cutting tool mounted on a tool mounting portion, a driving mechanism to move the tool relative to the substrate, and an oscillator to oscillate the cutting tool in specific phases, ensuring that oscillations at the start and end points of each cutting set are in phase and that oscillations between sets are also synchronized, thereby maintaining waveform continuity.

Engineering Contradiction Analysis
1Illumination intensity
If a cutting tool is oscillated during the cutting process, then the optical properties of the transfer object can be improved, but defects such as breaking of the oscillation waveform continuity may occur on the surface of the transfer object
Solution Approach 1:
The control device monitors the oscillation state of the cutting tool and adjusts the oscillation parameters in real-time to maintain waveform continuity. By implementing feedback control, the system can detect and correct phase disruptions caused by multiple sets of cutting processes, ensuring that the oscillation waveform remains continuous across different cutting sets while preserving the optical properties of the transfer object
Solution Approach 2:
The method pre-establishes phase relationship parameters for multiple sets of cutting processes before execution. By calculating and setting the appropriate phase offsets in advance for each cutting set, the system ensures that oscillation waveforms will be continuous when the cutting processes are executed sequentially, preventing waveform breaking while maintaining optical quality
2Length of moving object
If multiple sets of cutting processes are performed, then the cutting depth can be increased, but phase discontinuity between sets may cause waveform breaking
Solution Approach 1:
The oscillation parameters of the cutting tool are dynamically adjusted between different cutting sets. The system varies the oscillation phase and timing based on the specific requirements of each cutting set, allowing the cutting depth to be increased through multiple passes while maintaining phase continuity and waveform integrity across all sets
