Optimization of Twist Drill’s Geometry for Cast Iron
A new special drill is developed for iron cast drilling. The special drill has double point angle and 0°chisel rake angle which can decrease cutting force, tool wear and cutting temperature. Drilling performance is evaluated by trust force, torque, tool wear. The results indicate that new special drill is suitable for iron cast drilling with small cutting force and long tool life.
