Abstract

This paper presents a study of vibration characteristics in headstock of a lathe machine, at

different cutting parameters. These parameters are the cutting speed; the depth of cut lnq the feed rate

.The transducer were used on the heidstock in two directions, the vertical and horizontal (feed) direction,

Also for a time domain of (l0sec) in both directions. The results show that the effect of the vertical

vibrations is more significanf than the horizontal (feed) direction, for all of the cases investigated in this

paper. Unlike the veriical vibration, the horizontal vibration is lower and steadier, when the cutting speed,

ine Oepttr of cut and the feed rate are increased, Whereas the vertical vibration shows a great fluctuation

when these parameters are increased.

Keywords : Vibration charasteristics, cutting parameters, head stock.
