研究目的
Optimizing laser microgrooving parameters on Hydroxyapetite bioceramic for improved machining responses.
研究成果
The study successfully optimized laser grooving parameters on Hydroxyapetite bioceramic using Taguchi based grey relational analysis. The optimal parameters improved overcut by 16.47% and groove depth by 2.75%, demonstrating the feasibility of the proposed method for improving machined microgroove characteristics.
研究不足
The study is limited to the optimization of laser grooving parameters on Hydroxyapetite bioceramic. The effects of other potential parameters and materials were not explored.
1：Experimental Design and Method Selection:
Taguchi methodology for four factors at three levels was used for the experiments. Grey relational analysis (GRA) was applied for optimization.
2：Sample Selection and Data Sources:
Hydroxyapatite (HAp) bioceramic material was used for the study.
3：List of Experimental Equipment and Materials:
A 50 watts nanosecond pulsed Nd:YAG laser-based CNC machining system was used. An optical measuring microscope (Olympus STM6) was used for measurements.
4：Experimental Procedures and Operational Workflow:
Laser microgrooving was performed with varying lamp current, pulse frequency, assist gas pressure, and cutting speed. Overcut and groove depth were measured.
5：Data Analysis Methods:
ANOVA was used to identify significant factors. Grey relational analysis was used for multi-objective optimization.
