High-speed machining of titanium alloys is commonly used in the aerospace, automotive, and biomedical industries due to the high strength-to-weight ratio and corrosion resistance of these materials. However, the machining of these alloys is challenging due to their low thermal conductivity, high chemical reactivity, and low machinability. In addition, tool wear is a common issue in the high-speed machining of titanium alloys, which can lead to poor surface finish, dimensional errors, and increased scrap rates. Therefore, understanding the effects of tool wear on surface roughness and dimensional accuracy is crucial for improving the quality and efficiency of titanium machining. Furthermore, identifying effective methods for compensating for tool wear can help to maintain consistent part quality and minimize scrap rates. This study aims to investigate the effects of tool wear on surface roughness and dimensional accuracy in high-speed machining of titanium alloys and explore potential methods for compensating for tool wear to improve machining performance.
Tool wear affects surface roughness and dimensional accuracy in high-speed machining of titanium alloys because wear leads to tool wear flutes, which is when the tool’s cutting edge becomes dull and rounded. This reduces the cutting efficiency and leads to an increase in surface roughness. In addition, tool wear also leads to a decrease in dimensional accuracy due to the inability of the tool to cut as precisely as it once did.
