| Outline of Final Research Achievements |
In cutting of titanium, it is necessary to use a large amount of coolant for cooling and lubrication of the cutting point, increasing the environmental burden and the production cost. In this research, an experimental study was conducted to clarify the cause of the wear reduction effect by performing the cutting process in a reducing atmosphere such as nitrogen gas. From the analytical results towards the tool-workpiece thermocouple method, there is no difference in the interface temperature between the cutting tool and the workpiece in dry and nitrogen atmosphere cutting of carbon steel, while the oxide film thickness on the chip generated surface side is 30 nm or less It was revealed that it was suppressed by nitrogen gas. From the above, it was revealed that the effect of suppressing tool wear by cutting atmosphere control is not a thermal factor but suppression of chemical reaction during cutting process.
