ABSTRACT This research is motivated by the development of engineering science in industry which has experienced significant progress in the last few decades. Apart from that, there is still a lack of research related to the surface roughness analysis on materials influenced by hardening processes with different cooling media. This research aims to carry out the CNC Turning machining process on SCM440 material with different cooling media treatments and analyze the level of surface roughness on machining parameters. The machining variables from this research are spindle speed and feed rate in the CNC Turning machining process. The research process will start with the hardening process using the quenching method on the test sample, the machining process, the roughness test, and data analysis. The research results showed that the best hardness value for the room-temperature cooling media was 244.4 HB and the lowest hardness value for the water-cooling media was 172.82 HB. Apart from that, the hardness sample HB 172.82 has a rougher level and the highest hardness sample HB 244.4 has a low roughness level in Ra and Rq. |
