摘　　要：针对锆基非晶合金螺纹孔铣削加工存在的加工效率低、刀具寿命差等问题,本文研究切削速度和进给量对锆基非晶合金螺纹孔铣削中的切削力、刀具磨损和螺纹孔尺寸的影响,揭示涂层螺纹铣刀的刀具磨损形式,并优化适用于锆基非晶合金螺纹孔铣削加工的铣削工艺参数。结果表明,热软化效应是切削力在低进给量下随切削速度增加而降低的根本原因;相较于切削速度,进给量对切削力、刀具磨损和螺纹孔尺寸的影响更为显著;黏结磨损引起的涂层剥落致使切削力增大而崩刃是螺纹铣刀刀具失效和螺纹孔中径尺寸下降的根本原因。通过优化螺纹孔铣削加工工艺,可实现锆基非晶合金螺纹孔无晶化高效高质量加工。In addressing the challenges associated with low processing efficiency and the short lifespan of cutting tools in the milling of threaded holes in zirconium-based amorphous alloys,this study investigates the impact of cutting speed and feed rate on cutting forces,tool wear,and the dimensions of threaded holes.The research reveals the patterns of tool wear for coated thread milling cutters and optimizes the milling parameters for the threading process in zirconium-based amorphous alloys.The findings suggest that the thermal softening effect is principally responsible for the reduction in cutting forces as cutting speed increases at low feed rates.The feed rate has a more pronounced influence on cutting forces,tool wear,and dimensional accuracy of threaded holes when compared to cutting speed.Additionally,adhesive wear resulting in the delamination of the coating leads to an increase in cutting forces and chipping,which are identified as main causes of tool failure and reduction in the diameter of threaded holes.Optimization of the threading milling process facilitates the efficient and high-quality production of crystallization-free threaded holes in zirconium-based amorphous alloys.
