Abstract

The purpose of this research is to study the contribution and effect of coolant to machined surface integrity in term of roundness. The process of grinding was done by Universal Cylindrical Grinder Model OD 820 S with variable speed table and full CNC wheel head indeed manufactured by SHARP Precision Machine Tools. The parameters involved in this analysis include depth of cut, work head speed and traverse speed which are set as followed to previous parameter analysis based on the design of experiment (DOE). All other parameters are constant such as coolant which is Pretech Cool Syn 3000 Green with three difference brix concentration and abrasive wheel speed which is 1960 rpm. The roundness test will be performing using the CNC roundness at the Metrology Lab and method that used to determine the roundness of each sample is Least Square Circle Method. The result analysis was done based on roundness value from CNC roundness tester.
