Abstract

In manufacturing industries, surface quality of machining parts is one of the most customers demand. The major indication of surface quality on machine parts is surface roughness. Therefore, this project presents the experimental investigation for the effect spindle speed and feed rate on the surface roughness of medium carbon steel with series number 1045 (AISI 1045). This experiment was conducted by CNC turning machine mainly focused on dry cutting operation. Type of insert used in the experiment was Carbide insert with three edges of Sanvik Coromant brand with ISO number ZP 352 TNMG 160404-MB. The value of surface roughness, tool wear and chip formation were observed for two different values of feed rate, 0.15 mm/rev and 0.50 mm/rev. The values of spindle speed were 275 mm/min, 325 mm/min, 375 mm/min and 425 mm/min with constant depth of cut of 1 mm. These values were taken within the minimum and maximum value of spindle speed and feed rate that can be referred from the ISO code of Sandvik Coromant carbide insert. A surface roughness tester has been used to measure the surface roughness of the AISI 1045. Meanwhile, the tool wear on the inserts have been observed by using an optical microscope. The chips produced were taken for additional data and discussion of this study. From the analysis, the result showed that the spindle speed and feed rate were influenced the surface roughness of the AISI 1045. The results also showed that tool wear occurred at the carbide inserts with different values at different parameters. This study, will help to understand the effect of spindle speed and feed rate on the surface roughness in dry machining condition and identify the optimum parameters based on the characterization study.
