A study on the Machinability of SSW2 Steel(1st Report)

SSW2의 피삭성에 관한 연구 제1보

The turning tests with sintered carbide tools have been conducted on typical high strength SSW2 railway wheel steel and its machinability were examined in terms of the cutting resistance, the roughness of turning surface, the chip disposal and others. Some results obtained in this paper are as follows: (1) The cutting resistance is not affected by the cutting speed (in this paper these were 23-78 m/min). (2) The roughness of finished surface is found to be largely dependent on cutting conditions and tool geometry. (3) There exists the explicit relates between the tool geometry cutting conditions (cutting speed, feedrate, and depth of cut) and independent variables(cutting resistance, surface roughness) are derived.
