Abstract :
The process of machining fineness or the level of surface roughness of the workpiece produced greatly affects the quality of the product, by observing from several parameters one of them is the use of coolant or lubricant. This experiment made several variations of the use of coolant between coolant water, oil and air in the ST 40 steel turning process. The parameters used were 3 mm cutting depth, 300 Rpm spindle rotation speed. After that, the measurement of the average surface roughness (Ra) is done to determine the lowest variation of the (Ra) value produced. The use of coolant water coolant obtained an average surface roughness value (Ra) 4,479?m, the use of oil coolant obtained an average surface hardness value (Ra) 3,623?m, the use of air conditioning liquid obtained an average surface roughness value (Ra) 5,338 ?m. So that from the ST 40 steel turning process using the HSS lathe tool the lowest surface roughness value was obtained using oil cooling media.
