A comparison of dry and air-cooled turning of grey cast iron with mixed oxide ceramic tool

Comparison of Dry and Flood Turning in Terms of Dimensional Accuracy and Surface Finish of Turned Parts

“…A number of studies have reported on comparisons of different types of turning operations in terms of various machining performance characteristics such as tool wear [1][2][3], cutting force [4], cutting temperature [4], and productivity [5]. Comparatively, there have been relatively few studies reporting on the dimensional accuracy of turned parts [6], even though, in the majority of cases, dimensional accuracy is the first criterion in determining the acceptability of manufactured parts.…”

“…Comparatively, there have been relatively few studies reporting on the dimensional accuracy of turned parts [6], even though, in the majority of cases, dimensional accuracy is the first criterion in determining the acceptability of manufactured parts. Nonetheless, a number of publications [3,6] have reported on comparisons of surface roughness achievable by different types of turning operations. In [7], an attempt was made to compare the shortcomings of dry turning over flood turning by monitoring the dimensional accuracy and surface finish characteristics of turned parts.…”

An Overview on Turning Process

“…A comparative studies between dry and air-cooled turning of grey cast iron with oxide added ceramic tool was carried out by Sarma and Dixit [23]. They found lower cutting force and better surface finish with air cooled turning as compared to the dry turning as shown in Figs.…”

“…The coating materials of cutting tools are also responsible for quality machining, such phenomenon analysed by Aslan [54]. Sarma and Dixit [23] investigated that air cooled turning gives better surface finish with low tool wear as compared to the dry turning. Cutting tool geometry is also responsible to cutting.…”

“…Enfim, a literatura traz força de corte variando entre 300 e 700 N no torneamento do ferro fundido cinzento, todavia esses valores variam com a geometria do corte e com as condições de operação (SARMA; DIXIT, 2007;SOUZA et al, 2009 Fig. 85, é possível verificar a influência de v c nos testes (T02 e T04) e sutilmente para (T01 e T03), porém no que se refere aos testes (T06 e T08) e (T05 e T07), problemas relacionados a imperfeições geométricas no raio de ponta e avarias,…”
