Research on Wear Resistance and Cutting Performance of New Coated Cutting Tools under Different Cutting Conditions

Abstract

This study investigates the wear resistance and cutting performance of new coated cutting tools under various cutting conditions. The objective was to evaluate how different coatings and machining parameters affect tool life and efficiency. The experimental setup included a range of workpiece materials, such as low-carbon steel, stainless steel, and aluminum alloys, to simulate real-world machining scenarios. Coated cutting tools with various coatings, including titanium nitride (TiN), aluminum oxide (Al2O3), and titanium aluminum nitride (TiAlN), were tested for their performance. The wear resistance analysis revealed that tool coatings significantly influence the rate of wear and tool life. Tools with TiN coatings showed lower wear rates when machining stainless steel, while Al2O3 coatings performed better with aluminum alloys. The cutting performance evaluation indicated that coated tools maintained precision and efficiency, leading to smoother machined surfaces and extended tool life. The study also found that the optimization of cutting conditions, such as cutting speed and feed rate, in conjunction with the appropriate tool coating, resulted in the best performance. The conclusions drawn from this research emphasize the importance of selecting the right tool coating and cutting parameters for specific materials to enhance machining efficiency and reduce costs. The study provides valuable data for the manufacturing industry to optimize their processes and suggests areas for future research, such as the development of advanced coatings and the exploration of new tool materials.
