Several detailed studies have comprehensively investigated the benefits and limitations of laser-assisted machining (LAM) of titanium alloys. These studies have highlighted the positive impact of the application of laser preheating on reducing cutting forces and improving productivity but have also identified the detrimental effect of LAM on tool life. This paper seeks to evaluate a series of the most common cutting tools with different coating types used in the machining of titanium alloys to identify whether coating type has a dramatic effect on the dominant tool wear mechanisms active during the process. The findings provide a clear illustration that the challenges facing the application of LAM are associated with the development of new types of cutting tools which are not subjected to the diffusion-controlled wear processes that dominate the performance of current cutting tools.

几项详细的研究全面研究了钛合金激光辅助加工（LAM）的优点和局限性。这些研究突出了激光预热的应用对降低切削力和提高生产率的积极影响，但也确定了LAM对刀具寿命的不利影响。本文旨在评估一系列用于钛合金加工的具有不同涂层类型的最常见切削刀具，以确定涂层类型是否对加工过程中有效的主要刀具磨损机理产生显着影响。
