研究目的
Investigating the geometrical characteristics in low power fiber laser drilling of Monel k-500 superalloy.
研究成果
The study successfully demonstrates the effect of sawing angle in low power laser trepan drilling of Monel k-500 alloy sheet. Optimal parameter settings for minimum hole taper are identified, and the developed models show good agreement with experimental results. The findings highlight the importance of sawing angle, duty cycle, and pulse frequency in controlling hole taper.
研究不足
The study is limited to the use of a low power fiber laser (50 W) and specific input parameters like sawing angle, power setting, duty cycle, pulse frequency, and trepanning speed. The applicability of the findings to other materials or higher power lasers is not explored.
1：Experimental Design and Method Selection:
The study utilizes response surface methodology (RSM) for optimization, handling the non-linearity and complexity of the laser drilling process.
2：Sample Selection and Data Sources:
Monel k-500 metal alloy sheet specimens with a thickness of
3：7 mm are used as workpiece material. List of Experimental Equipment and Materials:
The experiment is carried out on a pulsed mode CNC fiber laser machine with a maximum average power of 50 W.
4：Experimental Procedures and Operational Workflow:
A central composite design (CCD) is used to analyze the effect of five main laser micro drilling input process parameters.
5：Data Analysis Methods:
ANOVA test is applied for model validation, and empirical models are developed to relate different quality characteristics.
