激光辅助铣削(LAML)技术是难加工材料的有效加工方法,通过激光照射可提高材料的温度,改善其加工性能。本文通过对高温合金GH4698材料进行激光辅助铣削试验研究,分析了激光与工艺参数对切削力、刀具磨损及已加工表面质量的影响规律。结果表明,激光辅助铣削可以在不改变GH4698的组织结构及材料性能前提下降低切削力和刀具磨损,提高加工质量。
Laser assisted milling (LAML) technology is an effective machining method for difficult-to-machine materials, which increase the temperature of the material and improve its processability through laser irradiation. In this paper, laser-assisted milling of superalloy GH4698 was studied, and the influence of laser and process parameters on cutting force, tool wear and machined surface quality was analyzed. The results show that laser assisted milling can reduce the cutting force and tool wear and improve the machining quality without changing the structure and material properties of GH4698.
