Article Title: A Study of Vibration Produced by Thermoplastic Engineering Gear and Constructional Steel Gear in the Lathe Drive during Machining
by Ademola Samuel Akinwonmi and Stephen Kwasi Adzimah

In this paper, the effect of vibration on different engineering thermoplastic (Polyurethane Polyamide, Polyformaldehyde) and Constructional steel gear materials has been studied. The major parameters used in the research are the depth of cut and spindle speed. The depth of cut is varied while the spindle speed is kept constant for every gear material. The depth of cut used in this experiment are (0.25, 0.50, 0.75, 1.00) mm. The cutting tool vibrations are measured by using measured using Piezoelectric Accelerometer model KB12 and recorded for the four spindle speeds (360, 720, 1080, 1440) rev/min for the various gear materials of the feed box. The graphs are plotted between the cutting tool vibrations along y-coordinate and spindle speed along x-coordinate for different gear materials along with constructional steel gear as a reference. The result showed that Vibration of the cutting tool increases as the depth of cut increases either with Thermoplastic gear or Constructional Steel Iron gear, vibrations produced during machining operations are higher in Constructional steel gears than the thermoplastic gears. The purpose and significance of this research is to see how vibrations produced by varying depth of cuts using different gear materials affect the accuracy and dimensional stability of machined surfaces. This paper is limited to varying depth of cut and constant spindle speed for every gear material. Further research should be carried out keeping the depth of cut constant and the spindle speed varied
