Area of Science:

• Materials Science and Engineering
• Manufacturing Technology
• Laser Processing

Background:

• Metallic materials like SS41 and SUS304 are crucial in high-tech industries (aerospace, automotive).
• Conventional cutting methods struggle to meet the high precision demands of modern industrialization.
• Laser manufacturing offers a solution for achieving high-precision cutting of engineering materials.

Purpose of the Study:

• To investigate the impact of laser parameters on the quality of laser-cut SS41 and SUS304.
• To analyze the relationship between laser cutting variables and process outcomes.
• To establish optimal parameters for high-precision laser machining.

Main Methods:

• Utilized a continuous wave CO2 laser cutting system for SS41 and SUS304.
• Varied experimental parameters including laser cutting speed and laser power.
• Measured top/bottom kerf widths, melting zone, and Heat Affected Zone (HAZ) for process quality evaluation.

Main Results:

• Laser parameters significantly influence the process quality of laser cutting.
• Kerf width, melting zone, and HAZ dimensions were correlated with laser parameters.
• Analysis of Variance (ANOVA) determined the contribution of laser parameters to material effects.

Conclusions:

• Laser cutting parameters critically affect the precision and quality of SS41 and SUS304 machining.
• Multiple regression analysis effectively predicts cutting quality metrics based on laser parameters.
• Understanding these correlations is vital for achieving optimal laser cutting outcomes.
