The high speed machining has been widely applied to manufacture a die and machine elements product in industrial field. Especially, 5-axis milling has been employed to produce a wide range of turbine blades, impellers and complex molds. In this study, machining characteristics of injection mold was investigated according to tool position control. The cutting force and surface roughness were measured with various tool position angles. When the tool position angle was over 25 degree, the cutting force was decreased and surface roughness was good compared with low tool position angles.
