Article Preview

High speed machining is very popular and widely used in industry recently, and it has been accepted as a key technology for die and mold steel manufacturing because it has much advantage as compared with conventional machining such as low cutting resistance, low cutting heat generation and high production rate, etc. The finite element method is utilized in this study to simulate the processes of chip formation during high speed machining of SKD11 die steel workpiece step by step from an incipient of tool-workpiece engagement to a steady state of chip formation. The effects of different combinations of cutting conditions such as cutting velocity, feed rate, rake angle and nose radius of the tool on the curly types of chip formation are investigated thoroughly for establishing the related skill for high speed machining or for predicting the chip morphology in advance.
