The effects of frequency in ultrasonic vibration assisted milling (UVAM) with axial vibration of the cutter is investigated in this paper. A series of face-mill experiment in dry conditions were conducted on AISI 316L, an alloy of widespread use in industry. The finished surfaces roughness were studied along with basic considerations on tool wear for both conventional milling and an array of frequencies for UVAM (20–40–60 kHz) in a wide range of cutting conditions. Surface residual stresses and cross-cut metallographic slides were used to investigate the hidden effects of UVAM. Experimental results showed competitive results for both surface roughness and residual stress in UVAM when compared with conventional milling especially in the low range of frequency with similar trend for tool wear.
本文研究了刀具轴向振动的超声振动辅助铣削（UVAM）中频率的影响。在工业上广泛使用的合金AISI 316L上进行了一系列干燥条件下的面铣实验。研究了在广泛的切削条件下，传统铣削和一系列频率（20 - 40 - 60 kHz）的UVAM加工后的表面粗糙度，并对刀具磨损进行了基本考量。通过表面残余应力和横向金相切片来研究UVAM的潜在影响。实验结果表明，与传统铣削相比，UVAM在表面粗糙度和残余应力方面都有较好的结果，特别是在低频范围内，刀具磨损趋势相似。
