Investigation of tool life with Simple and viper ceramic tools in near dry machining in high speed turning

Using of minimum quantity of lubricant in near dry machining is one the new method in machining processes that causes improvement of process. In this study، the role of near dry lubrication is investigated on tool wear in turning of Monel K500. The used tools are consisted of simple and viper ceramic tools. After preparation of process on lathe machine، the designed experiments are done. During the experiments force، surface roughness and tool wear are measured. The obtained results confirm that near dry lubrication causes the reduction of tool wear considerably. Also، viper ceramic tool has less tool wear rather than simple ceramic tool.
