Analysis Comparative Feeding Variation to Quality Surface Processes Blocking Equipment of Ems Steel 45on Cnc Latheing Machine

Abstract

This research aims to analysis comparative feeding variation to quality surface processes blocking equipment of ems steel 45on cnc latheing machine. Quality products are obtained from good cutting conditions. One of the most important variable cutting conditions to obtain surface roughness quality is feeding. The purpose of this study was to see the comparison of feeding variations of G94 and G95. The multilevel cutting process is carried out with a cutting depth of 0.5 mm and a length of 40 mm with a carbide cutter with feeding variations (G94 / G95) of 0.3048 mm / min and 0.3281 mm / min respectively and at the price of the round / cutting speed speed (G97 / G96) is controlled. Surface roughness testing using Surface Tester Mitutoyo SJ-201P. The result of this research can be concluded that the higher the surface roughness obtained is lower compared to the average price of roughness of the lathe result that uses low feed.
