ABSTRACT
The metal industries (lathe workshops) usually carries out their activities of metal cutting by using coolant which aims to obtain a long tool life and to obtain the standarized level of surface roughness; however, the use of such coolant has negative impacts on the machine operators who can have lung and temporary skin problems as well ason the environment which can be polluted. All this is caused by the fact that the coolant is a synthetic material that cannot be decomposed in nature and for this reason scientists try to eliminate the use of coolant for metal machining. As a result, the operation cost can be minimized and no coolant disposal can be found in the environment. In this paper the dry machining test on cast iron has been carried out. After the test, some information on tool wear (VB), machining time (t), surface roughness (Ra), machining length (lm), machining volume (Vm) and material removal rate (MRR) was obtained. The data from the test results were analyzed and from five cutting conditions, the best conditions were obtained, which could be applied for environmentally friendly machining (or green machining).
