TLDR
In this article, the effect of machining parameters on a surface roughness in a lathe boring operation in dry condition was analyzed using analysis of variance, and the results showed that using larger tool nose radius always gives a good surface finish.Abstract:
The role of surface roughness is very important in machining processes. The surface finish and tolerances are most critical quality measures in various mechanical products. The main objective of this paper is to find out the effect of machining parameters on a surface roughness in a lathe boring operation in dry condition. This paper shows the study of surface roughness for boring of gray cast iron (250BHN) by using carbide tool under dry condition. The effect of boring parameters (tool nose radius, feed, spindle speed and depth of cut) was analyzed using analysis of variance. These variables were computed using Taguchi’s design of experiments (DOE). The DOE gives the optimal values of speed, feed and depth of cut for tool nose radius of 0.4 and 0.8 mm. The three-factor three-level fractional experiments were conducted. This result shows that the effects of speed, feed, depth of cut and tool nose radius on surface finish are statistically significant. The results observed that using larger tool nose radius always gives a good surface finish. The results also revealed that the following level for each of the factors produces the smooth surface finish within the range of experiments: larger tool nose radius, lower feed, higher speed and lower depth of cut.read more

Dry machining: Machining of the future
TL;DR: In this paper, the authors present recent developments in the dry machining operation and discuss the benefits of using cutting fluids for green machining, and also point out that some benefits of cutting fluids are not going to be available for dry machine and also dry machinings will be acceptable only whenever the part quality and machining times achieved in wet machining are equalled or surpassed.
