Özet:

 


In this study, AISI 4140 tempering
steel with 48 HRc hardness was machined on CNC lathe with different cutting
parameters and cooling environment. The Taguchi L9 test design was
developed based on the three-level cutting speed, feed, chip depth and cooling
environment parameters. The average surface roughness (Ra) values were measured
in experiments made according to the L9 test design. Chip form
occurring during turning is photographed. The Signal/Noise (S/N) ratios of the
Taguchi experiment design in the Minitab program have been determined.
According to the experimental results, the most significant effect on the Ra
from the four factors was found in the hand made by the depth of cut. In ANOVA
analysis, it was respectively determined that depth of cut, cutting speed, feed
rate and cooling environment affected 95% confidence in Ra value. It has been
found that the repeat experiments for the optimum parameters yielded about 90%
accuracy compared to the Taguchi estimate.
