| Abstract: | This paper studies the influence of radial depth on vibration, chip formation and surface roughness during face milling of
AISI304 austenitic stainless steel with indexable cemented carbide milling cutters. The amplitude of vibration acceleration
increased with the increasing radial depth up to 80 mm. And the domain vibration frequency varied with the radial depth. In
this paper, three types of chips were found: C shape, long shape and spiral shape. The minimum surface roughness value occurred
when the radial depth equalled 40 mm in the experiment. Irregular changes of chip curl radius and chip thickness could be
attributed to different numbers of alternately engaged teeth when the feed and speed were fixed. Surface roughness is related
to forced vibration and chip formation. Radial depth with different numbers of alternately engaged teeth could significantly
influence the forced vibration, chip formation, and surface roughness. |
