研究目的
To investigate the effects of process parameters on the machining characteristics of laser induced plasma micromachining using flowing water (F-LIPMM) and to optimize the process for creating micro-channels on stainless steel surfaces.
研究成果
The study successfully developed regression models for predicting micro-channel characteristics in F-LIPMM and identified optimal process parameters for high-quality micro-channel fabrication. The models showed good agreement with experimental results, demonstrating their potential for process optimization.
研究不足
The study focuses on micro-channels on stainless steel surfaces and may not be directly applicable to other materials or more complex geometries without further research.
1：Experimental Design and Method Selection:
The study used response surface methodology (RSM) to design experiments investigating the effects of water speed, pulse energy, frequency, and scanning speed on micro-channel characteristics.
2：Sample Selection and Data Sources:
AISI 304 stainless steel sheets were used as test samples.
3：List of Experimental Equipment and Materials:
A commercial picosecond laser (PX50 by Edgewave) was used to generate plasma in distilled water. A confocal laser scanning microscope (OLS4100 by Olympus) was utilized for observation and measurement.
4：Experimental Procedures and Operational Workflow:
Micro-channels were created by overlapping induced plasmas, with each micro-channel scanned twice for depth.
5：Data Analysis Methods:
Regression models for width, depth, MRR, and HAZ were developed and verified using ANOVA.
